- Part Two: Crystal Reports
- =========================
-
- 9.0 Introduction to Crystal Reports
-
- This chapter introduces Crystal Reports, shows you how to start the
- program, introduces you to some of the things the program can do, and
- familiarizes you with some of the "nuts and bolts" of using the program.
-
- 9.1 About This Part of the Manual
-
- This part of the manual contains all of the information you should need
- for building reports quickly and easily using Crystal Reports. It is
- divided into three chapters:
-
- Chapter Description
- 9.0 Introduction to Crystal Reports Introduction gives you a brief
- overview of Crystal Reports. It
- familiarizes you with the Crystal
- Reports screens, using the mouse,
- error messages, and the help
- facility.
-
- 10.0 Using Crystal Reports This chapter conceptually leads you
- through the process of creating a
- report with Crystal Reports. It
- suggests a methodology for creating
- reports starting with nothing more
- than a one sentence statement of
- purpose for the report.
-
- 11.0 Practical Crystal Reports Practical Crystal Reports is a
- "How to" chapter. It contains a
- variety of report creation topics
- and additional information on the
- practical aspects of using Crystal
- Reports to solve typical reporting
- problems.
-
-
- For information on topics not found in these chapters, refer to the
- Crystal Reports Help system.
-
- This part of the manual assumes that you understand the basic concepts
- and usage of Microsoft DOS or PC-DOS, and Windows 3.0 or higher. The
- procedures also assume that you will be using a mouse in the creation of
- your reports. While the instructions occasionally indicate keyboard
- methods for using the program, the instructions are generally
- mouse-oriented since most Windows users have a mouse.
-
- 9.1.1 Special Notations Used in this Part
-
- The following notations are used throughout this part of the manual:
-
- o Delete means the Del key on your numeric keypad.
-
- o Escape means the Escape or Esc key on your keyboard.
-
- o Enter means the Enter, Return, or CR key, depending on which of these
- keys appears on your keyboard.
-
- o Click means to click the left mouse button one time.
-
- o Double click means to click the left mouse button twice, in quick
- succession.
-
- o The term Cursor Keys means the Pg Up, Pg Dn, and Arrow Up, Arrow Down,
- Arrow Right, Arrow Left, Home, and End keys on your numeric keypad.
-
- o Ctrl+Key, Shift+Key, and Alt+Key are examples of the notation for two
- key combinations. They mean to press the first key in the combination
- (Control, Shift, or Alt), and, while keeping it depressed, to press the
- second key in the combination (designated as Key).
-
- o Text enclosed in double brackets (for example, << information >>) is
- intended to expand or explain the information that it follows.
-
- o Field names in formulas are italicized.
-
- o Insert|Formula means to select the Formula option from the Insert menu.
-
- o Drag, when used in talking about field boxes, means to position the
- cursor on a field box, depress the left mouse button, and keep the button
- depressed while moving the field to a new position.
-
- o Drag, when used in talking about text, means to depress the left mouse
- button and, while it is depressed, move the I-beam cursor across the text
- of interest to highlight and thus select it.
-
- o Computer type indicates data that you are to enter using the computer
- keyboard. It is also used to show example formulas.
-
-
- 9.2 Starting Crystal Reports
-
- You can start Crystal Reports in two ways:
-
- o from the DOS command line
- o from the Windows environment.
-
- 9.2.1 From DOS
-
- To start Crystal Reports (and Windows at the same time) from the DOS
- command line, type:
-
- cd
-
- and the name of the directory into which you installed Crystal Reports.
- For example, if you installed Crystal Reports in the default Crystal
- Reports directory, type:
-
- cd \CRW
-
- and then press Enter.
-
- At the prompt, type:
-
- win CRW
-
- and press Enter. Windows and Crystal Reports are both started.
-
- 9.2.2 From Windows
-
- Once in Windows, select the group window that holds the Crystal Reports icon.
-
- o If you're using a mouse, double click on the Crystal Reports icon to
- start the program.
-
- o If you're using the keyboard, use the arrow keys to select the icon and
- then press Enter.
-
- You can also start Crystal Reports from within Windows by double clicking
- on the file name CRW.EXE in the File Manager.
-
- 9.2.3 The Crystal Reports Registration Dialog Box
-
- The Crystal Reports Registration dialog box appears whenever you start
- Crystal Reports unless you have registered your copy of the program with
- the company, received a serial number, and entered it in the Enter serial
- number... edit box to disable this opening dialog box.
-
- There are two good reasons to register your copy of Crystal Reports:
-
- o Registration entitles you to technical support should you ever require
- assistance in using the product.
-
- o Registration assures you that you will be notified whenever the
- product is upgraded to offer new features, benefits, and efficiencies.
-
- The Crystal Reports Registration dialog box options are as follows:
-
- o Enter serial number... edit box: Use this edit box to enter the
- serial number that Crystal Services sends you when you register the
- program. Be careful to enter the serial number correctly.
-
- o Proceed to Crystal Reports button: Use this button to close out
- the dialog box and go directly into the Crystal Reports program. The
- button will be useful until you receive and enter your registration
- serial number. At that time the Crystal Reports Registration dialog box
- will no longer appear when you start the program.
-
- o Edit Registration Info button: Use this button to enter/edit product
- registration information. The Edit Registration Info button takes you to
- the Crystal Reports Registration dialog box. Use this dialog box to enter
- your name, company name, and phone and fax numbers. Crystal Reports stores
- this information and displays it and/or prints it out automatically when you
- print out the registration form, call up system information (via the
- Help|System Information command), or send in a technical support request
- (via the Help|Technical Support Request command).
-
- o Print Registration Form button: Use this button to print a copy of
- the completed registration form.
-
- 9.2.4 How to Register Your Copy of Crystal Reports
-
- Use the following procedure to register your copy of Crystal Reports.
-
- 1. Click the Edit Registration Info button.
-
- The Crystal Reports Registration dialog box appears.

- 3. Click the Print Registration Form button.
-
- Crystal Reports prints out a copy of your completed registration form.
-
- 4. Fax the form to Crystal Services at the number that appears on the
- form, or mail it to Crystal Services at the address that appears on
- the form.
-
- 5. In a few days, the company will mail or fax you back your serial number.
-
- 6. Enter the serial number in the Enter serial number... edit box, and
- click the Proceed to Crystal Reports button when finished.
-
- This takes you to Crystal Reports and disables the dialog box so it no
- longer appears when you start the program.
-
-
- 9.3 Quick Start
-
- If you are an experienced Windows user who wants to get right into the
- program, follow these steps to set up a Crystal Reports report for the
- first time after you install the program.
-
- 1. Start Crystal Reports by double clicking on the Crystal Reports icon
- in the Program Manager.
-
- 2. Select New Report from the File menu.
-
- 3. When the Choose Database File dialog box appears, select the first
- database you want to activate for your report and press OK when finished.
-
- The Crystal Reports Report Editor appears with Page Header, Details,
- and Page Footer sections set up on your report template. The sections
- are all blank initially.
-
- Create your report by inserting and formatting items in each of
- these sections.
-
- 4. The Insert Database Field dialog box appears on screen with the Report
- Editor.
-
- The Insert Database Field dialog box displays a list of all of the
- fields in the active database. To speed the entry of multiple fields,
- the box remains on screen until you click on the Done button. You can
- move the dialog box to a new location if you wish.
-
- 5. Select the first field you want to appear on the report.
-
- A rectangular insertion cursor appears.
-
- 6. Position the cursor at the point in the Details section where you want
- your field to appear, and click the left mouse button to enter it.
-
- Crystal Reports marks the field position with a rectangular box. The
- characters in the box indicate whether the field is text (XXX...),
- number (555,...), dollar value ($555,...) date (YYYY-M...), or
- Boolean (T/F). The number of characters in the box indicate the
- number of characters allowed for the field in the database from which
- it came.
-
- 7. Repeat Steps 5 and 6 until you have placed all the fields you want to
- place.
-
- 8. To create a title, select Insert|Text Field, type in the information
- you want to appear, click Accept when finished, and position the field
- where you want it in the Page Header section.
-
- You can also insert database fields or special fields in that section
- from the Insert menu.
-
- 9. To see how your results will print, select Print To Window from the
- Print menu. Close the window when you are finished with your review.
-
- 10. If you want to:
-
- o change the placement or width of a field
- o format the field
- o insert a subtotal or grand total for a field
- o delete a field
-
- click the field box for that field. Black handles appear on the right
- and left sides of the field box to indicate that it has been selected.
-
- o To change the placement of the field, drag the field box to
- its new position using the mouse or the arrow keys. The arrow keys
- move the field box one grid position each time you press them.
-
- o To change the width of the field, drag the right or left handle
- using your mouse or use a Shift-Arrow combination on your keyboard.
-
- o To format or subtotal the field, click the right mouse button
- while the cursor is inside the field. A pop-up menu appears listing
- your various options.
-
- - To change the font, select Change Font and refine
- your selection using the Font dialog box when it appears.
-
- - To change the format (alignment within field; number,
- currency, or date display; etc.) select Change Format and
- refine your selection using the Field Format dialog box
- when it appears.
-
- - To insert a subtotal, select Insert Subtotal and refine
- your selection using the Insert Subtotal dialog box when
- it appears. In this dialog box you select the field and the
- condition that triggers a new subtotal whenever the field's
- value changes, and you select the sort direction: Ascending
- (A to Z, 1 to 9) or Descending (Z to A, 9 to 1). The
- program creates a new section to hold the subtotal.
-
- NOTE: The program automatically sorts the data (based on the field
- that triggers the subtotals) before it subtotals. Manually entering
- a subtotal sort is not necessary.
-
- - To insert a grand total, select Insert Grand Total. The
- program creates a new section to hold the grand total.
-
- - To delete the field, select Delete Field.
-
- 11. To create a formula to make data calculations or comparisons, select
- Formula Field from the Insert menu.
-
- Enter a name for your formula in the Insert Formula dialog box, and
- enter the formula itself in the Formula Editor when it appears. Enter
- fields, operators, and functions by selecting them from their respective
- scroll lists.
-
- You can get complete information on each available Function and
- Operator via the Help button, and you can check your formula syntax
- via the Check button. Entering a Crystal Reports formula is similar to
- entering a formula in a spreadsheet cell. When finished editing,
- select Accept and place the formula just like you do a database field.
-
- 12. To change the sort order, select Record Sort Order from the print menu.
-
- Select the field(s) you want Crystal Reports to use for sorting the
- report data.
-
- 13. To change the sort and group by field, select Group Section from the

- Select the group section of interest from the list that appears in the
- Edit Group Section (sections) dialog box, and select the new "trigger"
- field from the Edit Group Section (edit) dialog box when it appears.
-
- 14. If you want to limit your report to specific records (for example,
- the records of California customers that have YTD sales greater
- than $10,000), click the first field on which you want your selection
- to be based (in this case the State field) and choose Select Records
- from the Print menu or the right mouse button pop-up menu.
-
- Answer the questions that appear in the Select Records dialog box and
- click OK when finished. If your selection is based on more than one
- field, repeat the process with the remaining field(s) until you have
- completed entering your selection specifications.
-
- 15. When finished, you can print your report by selecting Print To Printer
- from the Print menu.
-
-
- 9.4 About Crystal Reports
-
- Crystal Reports is a powerful yet easy to use program for creating custom
- reports, lists, and form letters using data from your existing databases.
- The program works by establishing connections with one or more of your
- databases.
-
- Using these connections as conduits, Crystal Reports draws in the values
- from database fields you select and uses them in the report, either in
- their original form or as part of a formula that generates more
- sophisticated values.
-
- Crystal Reports was designed to work with all kinds of data: numbers,
- currency, text, dates, and Boolean (Yes/No) fields. It has a wide range of
- built-in tools that you can use to manipulate that data to fit your needs.
- Using these tools, you can:
-
- o make calculations and comparisons of data values,
- o calculate subtotals, and grand totals of field values,
- o calculate group averages, count the records in a group, and test
- for minimum and maximum values,
- o test for the presence of specific values,
- o present data only if certain conditions are met,
- o evaluate logical relationships between values,
- o convert data from one type to another,
- o merge text with other text,
- o merge text with data field data, and
- o perform numerous other useful, data-related activities.
-
- The data can be placed wherever you want it on the report, highlighted
- with special fonts and font sizes. With Crystal Reports, your reports can
- be as simple or as complex as your needs demand.
-
- 9.4.1 How Crystal Reports Prepares Reports
-
- Crystal Reports prepares reports by reading data in the database files
- you have selected and making that data available for use in your report.
-
- o If you wish to use data in a single data file, you simply choose that
- file when you create the report.
-
- o If you wish to use data in multiple data files, you need to select the
- files and also to indicate the field or fields in each file that Crystal
- Reports is to use to match data.
-
- NOTE: Crystal Reports does not write data to your original data files.
- Your original files remain unchanged using Crystal Reports, no matter how
- much you might manipulate the data you select.
-
- 9.4.2 Databases that Work with Crystal Reports
-
- Crystal Reports can build reports using the standard data files generated
- by dBASE for Windows and Paradox for Windows as well as with DOS versions
- of dBASE and Paradox.
-
-
- 9.5 The Crystal Reports Window
-
- The Crystal Reports window is simple and easy to understand:
- o the Title Bar appears at the top of the window,
- o the Menu Bar appears just below the Title Bar, and
- o the Button Bar appears just below the Menu Bar.
-
- 9.5.1 Title Bar
-
- The Title Bar displays the name of the program running in the window,
- Crystal Reports. You can use the title bar to activate the window
- (if the window is buried in a cascade of windows) or to move the window
- (by depressing the left mouse button with the pointer on the title bar
- and then, while the button is still depressed, dragging the window to a new
- location), or to maximize the window (by double clicking on the title bar).
-
- 9.5.2 The Menu Bar
-
- The Menu Bar is Crystal Reports' command center. Each option on the menu
- bar calls up a drop down menu of commands that you can use to create,
- modify, print, and save your reports.
-
- Each menu is listed in the table below:
-
- File The File menu includes commands you can use to open, close, and
- save files, to save files under a different file name, print the
- file to a printer, and create new report files. It also includes
- a command you can use to exit Crystal Reports. Additionally it
- contains a command that allows you to configure Crystal Reports
- to your specifications.
-
- Edit The Edit menu allows you to modify aspects of your report. The
- menu includes commands you can use to edit formulas, to edit and
- delete group sections, and to change summary operations. It also
- contains commands for cutting, copying, and pasting text, clearing
- (deleting) report elements, toggling the display of field names on
- and off, and changing your report title.
-
- Insert The Insert menu is the central menu you use for creating reports.
- The menu includes commands you can use to insert database fields,
- text fields, and formula fields; subtotals, grand totals,
- summaries (counts, averages, etc.), and group sections; print date,
- page number, record number and group number fields; and graphics,
- lines, and boxes.
-
- Format The Format menu includes commands for changing the look of the
- elements in your report. It includes commands for changing fonts,
- and formatting fields, report sections, graphics, lines, and boxes.
- The menu also provides commands for adding field borders as well as
- background color and drop shadows for your fields.
-
- Data- The Database menu is used to select and delete databases for use
- base with your reports, to change the alias you use to identify the
- database, and to link and unlink databases. It also has a command,
- File Location, for directing Crystal Reports to look for database
- files in new locations. Two verify commands can be used to adapt
- your reports to minor changes in database structure.
-
- Print The Print menu includes commands that let you print your report to a
- print window, to a disk file, or to a printer, print the report
- definition (a report describing your report), select the records
- or groups to be included in your report, select the order in which
- report data is to be sorted (by record or by group), and select a
- printer if you want the report to print on something other than the
- default printer.
-
- Window The Window menu includes commands that let you rearrange icons and
- windows. It also lists the report windows that are open and includes
- a command that lets you close all report windows at once, if desired.
-
- Help The Help menu includes a command that takes you to Crystal Reports'
- main help index, a command that will give you information about the
- Crystal Reports version you are using, and other help-related topics.
-
- 9.5.3 The Button Bar
-
- Crystal Reports groups several commonly-used commands on a Button Bar that
- remains on screen at all times (unless you choose to turn it off).
-
- Each command is represented by an individual button, and each button
- displays a graphic that visually describes the command. You activate
- Button Bar commands by clicking the appropriate button one time with the
- left mouse button. The Button Bar eliminates some of the steps needed to
- activate the included commands, and it can thus greatly speed your
- work in creating reports.
-
- 9.5.4 The Status Bar
-
- The status bar at the bottom of the report window displays valuable
- information to help you use Crystal Reports more efficiently:
-
- o Button bar functions: When the cursor is over a Button Bar button,
- the Status Bar displays a short description of the button's function.
-
- o Menu command descriptions: When you highlight a menu command, the
- Status Bar displays a short description of the command. To highlight a
- menu command, click the menu name and move to the command using the Down
- Arrow key.
-
- o Current selections: When you select or place a graphic, field, text
- field, graphic line or box, special field, or formula, the status bar
- displays the name of the item selected. It displays:
-
- - the file name for a graphic,
- - the alias and field name for a field,
- - the text in a text field,
- - the words Line for a line and Box for a box,
- - the field type for special fields (PrintDate, RecordNumber, etc.)
- - the formula name for a formula.
-
- o Graphic Coordinates: When you select or create a bit-mapped graphic,
- a graphic box, or a graphic line, the program displays the coordinates
- for the left, right, top, and bottom sides of the graphic element.
-
-
- 9.6 Right Mouse-Button Capabilities
-
- When you are working in the Report Editor, you can speed up your work
- considerably using Crystal Reports' right mouse button capabilities. When
- the cursor is positioned on a report element (a field, a group field, a
- formula, etc.) and you click the right mouse button, Crystal Reports
- displays a pop-up menu right next to the element. Unlike Crystal Reports'
- standard menus that group commands by function (editing, inserting, etc.),
- these pop-up menus are element-specific: that is, they contain only those
- commands from Crystal Reports' primary menus that are available for
- use with the selected element.
-
- The pop-up menus are valuable because:
-
- o they display the name and source (alias) of the element at the top of
- the menu so you can identify the elements on your report with a single
- mouse click,
-
- o they appear right next to the selected element making them quicker and
- easier to access than Crystal Reports' main menus,
-
- o they contain only the commands you need; you don't need to search for
- commands on a more comprehensive menu,
-
- o they make it easier to learn Crystal Reports because:
-
- - they eliminate the need to remember where to find a command, and
- - they make it easier to pick the right command since you're dealing
- with only a compact list of, and
-
- o they spotlight the things you can do with an element making it an
- easier system to use when you are under pressure or distracted.
-
- Use the following procedure to use the right mouse button menus:
-
- 1. Position the cursor on the element of interest.
-
- 2. Click the right mouse button.
-
- The pop-up menu appears.
-
- 3. Select the command of interest from the pop-up menu.
-
- These options work exactly like the corresponding options that appear
- on Crystal Reports' primary menus.
-
- For information on using any of these menu options, see the corresponding
- option in Crystal Reports Help.
-
- NOTE: If you have swapped left/right mouse buttons via the Control Panel,
- the left mouse button will activate the pop-up menus.
-
-
- 9.7 Crystal Reports Report Windows
-
- When a Crystal Reports report appears, it appears in a report window. A
- report window has a title bar, minimize and maximize buttons, and a
- control menu box like the Crystal Reports window.
-
- Unlike the Crystal Reports window, the report window does not have its own
- menu. Instead, the commands from the Crystal Reports menu remain visible and
- are active for the document window.
-
- Also unlike the Crystal Reports window, the document window has scroll
- bars at the bottom and along the right hand edge. Usinh these scroll bars
- you can reveal parts of the document that aren't immediately showing in the
- window.
-
-
- 9.8 Getting Help with Crystal Reports
-
- Crystal Reports offers a comprehensive help system to support you during
- every step of the report development process.
-
- 9.8.1 Context Sensitive Help
-
- Context sensitive help gives you immediate help with a screen element of
- interest (menu command, dialog box, etc.). The program takes you directly
- to the help information you seek without the need to traverse the indexing
- system.
-
- NOTE: To get help on a specific menu command, click the menu name and
- then use the Down Arrow key to highlight the command of interest. Once the
- command is highlighted, press F1.
-
- 9.8.2 Indexed Help
-
- Indexed help takes you to the help indexing system, a hierarchy of indexes
- which is designed to help you target your topic of interest. Using the
- indexing system, you can select a broad topic of interest from the first
- index and then narrow your selection using the next index that appears,
- then the next. etc.
-
-
- 10.0 Using Crystal Reports
-
- This chapter provides a structured approach to preparing reports with Crystal
- Reports.
-
- 10.1 Using Crystal Reports
-
- The approach of this chapter in preparing reports with Crystal Reports
- includes the following elements:
-
- o deciding on the content of your report,
- o developing a prototype on paper,
- o setting up the prototype using Crystal Reports,
- o manipulating the data with formulas and functions,
- o grouping, summarizing, and sorting your data,
- o editing and formatting the data,
- o specifying the records/groups to be included in the report, and
- o printing the finished report.
-
- This is not a hands-on chapter, but an important introduction that can
- make your report creation work more efficient and more satisfying. The
- chapter has been designed to provide you with a conceptual understanding
- of Crystal Reports as well as a brief introduction to Crystal Reports'
- powerful features.
-
-
- 10.2 Deciding on the Content of Your Report
-
- Before you do anything else, you should outline the information you want
- your report to provide. Use the following list of questions as a guide in
- making that outline:
-
- o What is the overall purpose of the report?
- o Who is going to read the report?
- o What is the report title going to be?
- o What information do you need besides the title to identify the report?
- - Where is that information to come from?
- - If the information exists in a database, what types of fields
- is the data stored in: number, text, etc.?
- o What identifying information do you want to appear at the bottom of
- each page?
- - Where is that information to come from?
- - If the information exists in a database, what types of fields
- is the data stored in: number, text, etc.?
- o What specific data do you want to appear in the body of the report?
- - Where is that data to come from?
- - Does that data exist in data fields or does it need to be
- calculated from data field values?
- - What kind of fields is the data stored in: number, text, etc.?
- - Do you want to show totals?
- - What kind?
- - What do you want to total?
- o What information, if any, do you want flagged on the report?
- - How do you want it flagged?
- o What information do you want highlighted in some way so that it really
- stands out?
- o Do you want the report to be based on all records in the database or
- only on specified records?
-
- 10.2.1 Purpose
-
- What is the overall purpose of the report?
-
- Reports are management tools. Their purpose is to help individuals quickly
- grasp the essential elements and relationships found in raw data so they
- can make effective decisions. For a report to be effective, it has to
- present the right data in a logical way. If it presents the wrong data or
- if it presents the right data in a haphazard manner, the report may slow
- the decision making process or even encourage incorrect decisions.
-
- A good starting place in the development of a report is to write out the
- purpose of the report in a sentence or two. The purpose statement helps you
- focus on your primary needs, and it gives your report both a starting point
- and a goal.
-
- Here are some examples of purpose statements:
-
- o The purpose of this report is to show monthly and year-to-date sales
- by sales rep, compare this year's numbers to last year, and flag reps who
- are seriously deficient.
-
- o The purpose of this report is to show sales activity for each item in
- inventory, and to suggest reorder quantities based on that activity.
-
- o The purpose of this report is to calculate bowling averages and
- handicaps for each member of the bowling league.
-
- Clarifying the purpose of the report before you start is a critical step in
- the overall process. A report without a clear purpose is like a meeting
- without a clear agenda; it rambles and accomplishes little.
-
- 10.2.2 Readers
-
- Who is going to read the report?
-
- A single report is often used by many individuals. A detailed, company-wide
- sales report, for example, may be used by sales reps, the regional sales
- manager, the national sales manager, and the Chief Operating Officer (COO).
-
- Each of these individuals will be interested in different aspects of the
- report.
-
- o A sales rep will use the report to evaluate his/her individual sales
- performance and to compare that performance to that of other reps in the
- region.
-
- o The regional sales manager will use the report to evaluate the reps in
- his/her region and to compare the region's performance to that of other
- regions.
-
- o The national sales manager will use the report to evaluate the
- performance of his/her regional managers and to compare overall sales to the
- current sales forecasts.
-
- o The COO will use the report to evaluate the performance of the Vice
- President of Marketing and the sales department as a whole, and to project
- such things as manufacturing needs, warehouse locations, etc.
-
- Since each of the users of the report has different interests, it is
- important to plan the report so it includes the information each of the
- users is looking for.
-
- 10.2.3 Title
-
- What is the report title going to be?
-
- Write out a working title for your report. You may decide to change it
- later, but at least you will have a title to use when creating your
- prototype report.
-
- 10.2.4 Other Header Information
-
- What information do you need besides the title to identify the report?
-
- Are you going to include identifying information in addition to your
- report title? You may wish to include the current date, information on
- who prepared the report, a block of text to describe the purpose of the
- report, the range of data covered, etc. If you are going to include such
- information, write it down so you can use it in preparing your prototype.
-
- 10.2.5 Header Information Sources
-
- Where is that information to come from?
-
- The information can come from a variety of sources, depending on the kind
- of information you plan to use. For example, the current date can be
- inserted using the Crystal Reports Insert|Print Date Field command.
- Information on who prepared the report might be drawn from individual data
- fields in the database(s) used. (If it is to be drawn from a database, what
- database? Or, what combination of databases?) A block of text can be
- created and entered on the face of the report itself. As you begin to think
- of where the information is to come from, you begin formally structuring
- the report.
-
- 10.2.6 Data Types in the Header
-
- If the information exists in a database, what types of fields contain the
- data: number, text, etc.?
-
- Crystal Reports uses different rules for working with different types of
- data. You will find it helpful later if you note the data type of each
- piece of data you plan to draw from a database.
-
- 10.2.7 Footer Information
-
- What identifying information do you want to appear at the bottom of each
- page (page number, report name, author's name, "Confidential," etc.)?
-
- 10.2.8 Footer Data Sources
-
- Where is that information to come from?
-
- 10.2.9 Data Types in the Footer
-
- If the information exists in a database, what types of fields is the data
- stored in: number, text, etc.?
-
- 10.2.10 Report Body Data
-
- What specific data do you want to appear in the body of the report?
-
- When you think of a report, it is probably the body of the report that you
- think of. The body should contain all the data that you need to fulfill the
- statement of purpose you wrote for the report. It should also contain all of
- the data needed by the various users that you have identified. You
- might find it helpful to list first the basic data that is required to
- fulfill the purpose statement, and then list the more specific kinds of data
- needed by the various users.
-
- 10.2.11 Body Data Sources
-
- Where is that data to come from?
-
- This step requires you to look at the available databases. Crystal Reports
- allows you to combine data from different databases to create your reports,
- so you have a great deal of flexibility in your work.
-
- o Much of the data in a typical report will be taken directly from data
- fields. Which data fields will you be using and where are they located?
-
- o Other data will be calculated based on data fields. Which data fields
- will be used in the calculations?
-
- o Still other data will be input directly into the report (headings, text
- blocks, etc.). Which data will you enter directly on the report, without
- drawing it from data fields?
-
- 10.2.12 Existing or Calculated?
-
- Does that data exist in data fields or does it need to be calculated from
- data field values?
-
- Some report information can be drawn directly from data fields (sales
- information, for example); other information will have to be calculated
- based on data field values (sales commission, for example, based on the
- relationship of sales to quota). In your planning, it can be helpful to
- segregate or flag data that needs to be calculated from that which can
- be used directly.
-
- 10.2.13 Data Types in the Body
-
- What kinds of fields contain the data: number, text, etc.?
-
- While it is important to understand data types for all data you will be
- using, it is of critical importance that you know the data type for data
- fields that will be used in calculations. Functions and operators work with
- specific kinds of data, so it's important to know the data type to
- know which functions and operators you can use in your calculations.
-
- 10.2.14 Groups
-
- Do you want your data organized into groups? How do you want it grouped? By
- customer? By date?
-
- 10.2.15 Group Values
-
- Do you want to show a subtotal at the end of each group? A count? An
- average? Crystal Reports allows you to specify several kinds of group values.
-
- 10.2.16 Group Value Positions
-
- Where do you want the group values to appear. With the group data? With the
- group data but on a page separate from other groups? Only at the bottom of
- the page? Crystal Reports gives you all of these options.
-
- 10.2.17 Grand Totals, Grand Total Averages, etc.
-
- Do you want to total (or average, count, or determine the maximum or
- minimum value included in) all the values in any column on your report?
-
- Crystal Reports allows you to do this and place the grand total (or the
- grand total average, grand total count, etc.) at the bottom of the selected
- column.
-
- 10.2.18 Flags
-
- What information, if any, do you want flagged on the report?
-
- You may want to call attention to some data by flagging it on your report.
- For example, non-moving inventory items are often flagged on inventory
- reports so they can be given special attention. If you want any information
- flagged, identify the information and the parameters for flagging.
-
- Using the inventory report example, you might want to flag each item that
- has shown no activity during the last month, during the last three months,
- or during some defined period.
-
- 10.2.19 Flag Options
-
- How do you want it flagged?
-
- You may want to flag items with an asterisk or some other symbol, or you
- may want a word to appear as a flag. In any case, you should write out
- flagging instructions so they are handy.
-
- 10.2.20 Highlights
-
- What information do you want highlighted in some way so that it really
- stands out?
-
- Crystal Reports gives you the opportunity to underline report elements, or
- to change the fonts or font size used for specific report items. All of
- these formatting tools can be used to highlight key data on a report. If
- you have data that you want highlighted, you should write down highlighting
- instructions so they are handy too.
-
- 10.2.21 Record or Group Selection
-
- Do you want the report to be based on all records or groups in the database
- or only on specified records or groups?
-
- Crystal Reports gives you the opportunity to base a report on all records in
- a given database, or on a limited set of records from the database. Using
- Crystal Reports you can select records based on simple date ranges or
- comparisons, or you can create complex formulas to identify the records
- to be included. Take a few minutes to determine the records needed for your
- report and list the criteria to be used for selecting those records.
-
- 10.2.22 Sorting
-
- Do you want your data sorted based on record or group values?
- Crystal Reports gives you both alternatives.
-
-
- 10.3 Developing a Prototype on Paper
-
- Graphic designers generally begin their work on a magazine cover,
- brochure, or display advertisement with a rough pencil sketch. They often
- use boxes, circles, or other symbols to represent the graphic elements they
- intend to include in the final product, and they often use lines or
- scribbles to represent text. Doing the rough design on paper, in pencil,
- helps them create a "look" for each page. It helps them find a balanced
- way of positioning the various elements before they begin working with
- sophisticated graphics tools. We think you will find a similar exercise
- helpful in designing your Crystal Reports reports.
-
- While a paper prototype is useful regardless of your expertise with Crystal
- Reports, it is particularly valuable when you are first learning to use the
- Crystal Reports program. With the paper prototype at hand, you can put your
- full effort into learning and using the Crystal Reports commands instead of
- trying to design and learn at the same time.
-
- Use the following procedure to design a paper prototype with Crystal Reports:
-
- o Get paper of the size you'll be using for your finished report.
- o Position your title and other descriptive header information, using
- boxes or lines to represent report elements.
- o Position your footer information.
- o Review the page for balance.
- o Look at the information you intend to include in the body of your report.
- - Count the number of fields you will be using and estimate the
- appropriate spacing between fields.
- - Use rectangles to pencil in the fields using your estimated spacing.
- - Change the spacing if necessary.
- - Decide on a logical sequence for presenting the report data.
- - Label the fields to indicate that sequence.
- o Use small boxes to indicate group values and totals.
- o Place some random flags where you want the flags to appear.
- o Darken any elements you want highlighted so they stand out from the
- rest of your prototype.
- o Review your finished product for look and balance, and make changes as
- needed.
-
-
- 10.4 Setting Up the Prototype Using Crystal Reports
-
- Once you have completed your paper prototype, it is a straightforward
- process to recreate that prototype in the computer, using Crystal Reports.
- Before you do, it is important to understand how Crystal Reports' report
- editing process works.
-
- NOTE: This section assumes that you are new to Crystal Reports and that
- you plan to build a simple report using data from a single database. No
- advanced topics are covered in this section.
-
- When you want to begin a new report, Crystal Reports displays the Choose
- Database File dialog box. You use this dialog box to select the database
- file(s) that contain the data you want to use in your report. You will
- first select the directory and, once in the directory, you can select the
- database file you identified earlier in Deciding on the Content of Your
- Report.
-
-
- 10.5 The Report Editor
-
- Once you select your database, Crystal Reports displays the Report Editor
- screen. You use this screen to insert and format data and to watch your
- report take shape.
-
- When you open a new report, Crystal Reports automatically creates three
- sections in the Report Editor:
-
- o A Page header section - this section is generally used for the report
- title, field headings, and other information that you want to appear at the
- top of each page.
- o A Details section - this section is the body of the report. The bulk of
- your report data will generally appear in this section.
- o A Page footer section - this section usually contains the page number
- and any other information that you want to appear on the bottom of each page.
-
- The name of each section appears in the gray area to the left of the Report
- Editor edit box.
-
- o You build your report by inserting data fields, formulas, and other
- report elements (record counts, record numbers, etc.) in the Details
- section of the editor. You use the Insert menu, in most cases, to select
- or create the elements you want to insert on the report. The Report Editor
- uses rectangular element markers to indicate the size, position, and data
- type of the report elements you have inserted.
-
- o You add subtotals (and other group values) by selecting a field to
- subtotal and then telling Crystal Reports the conditions that are to
- generate a new subtotal or group value (change of customer number, change
- of sales rep, etc.). Crystal Reports creates group value sections as
- needed and places the group value in the section. Again, Crystal Reports
- uses rectangular field boxes to represent the group values.
-
- o You insert grand totals in the Grand Total section. This section appears
- when you select the field to total and then select Insert|Grand Total.
- Crystal Reports uses a rectangular field box, this time to identify the
- field in the Grand Total section of the Report Editor.
-
- o You can add freeform text anywhere on the report by positioning the
- text cursor in the section in which you want the text to appear, typing in
- the text, and then using the Tab key to move it into position. You can also
- type freeform text in a text field; this allows you to avail yourself of
- additional formatting options (alignment, hide options, etc.).
-
- 10.5.1 Auto-Scrolling Capabilities
-
- The Report Editor has auto-scrolling capabilities. That is, whenever the
- cursor hits one of the edges of the Report Editor when you are placing,
- resizing, or moving a field or drawing a graphic line or box, the Editor
- automatically scrolls to reveal more workspace (if more is available).
-
- 10.5.2 Resizing Sections
-
- The Report Editor first appears with default section sizes. You can expand
- or reduce report sections by dragging the lines that separate the sections.
- When you position the I-beam cursor over one of those lines, the cursor
- changes to a double-arrow resizing cursor. Once that cursor appears,
- you can resize as needed. Alternately, to expand a report section, you can
- click the section of interest and press Enter as many times as needed. Once
- you've expanded a section, you can reduce it by deleting unneeded lines with
- the Backspace key.
-
- 10.5.3 A Word about Databases, Records and Fields
-
- Before we go any further, a discussion of databases, records, and fields
- is in order. A record is the basic building block of a database. Each record
- contains data about a single entity (a customer, an order, etc.), and each
- database contains at least one record. The data in each record is stored in
- fields (holding spaces). Each field holds one piece of data known as a value.
- The database from which you will create a report is a collection of related
- records. A customer database, for example, is a collection of records that
- each contain data on a single customer.
-
- 10.5.4 Records and Fields in Row/Column Reports
-
- Think of the data in a database as being stored in horizontal rows and
- vertical columns.
-
- CustNumber Fname Lname
- 01034456 Bill Brown
- 01034457 Jane Doe
- 01034458 Bob Jackson
- 01034459 Mary Jones
-
- The table above shows field values for four records from such a database
- (in this case a customer database).
-
- o Each row represents one record. All of the data in that row is about a
- single customer, but the data is broken into three distinct pieces: customer
- number, first name, and last name. Each of those pieces represents a
- value found in a field on that record, the CustNumber, Fname, and Lname
- fields respectively (as indicated by the column headings).
-
- o Each column represents one field. All the data in a given column
- represents the values that appear in that field on each of the records in
- the database.
-
- The structure of a row/column report corresponds to the structure of a
- database with rows representing individual records and columns
- representing individual fields.
-
- 10.5.5 Records and Fields in Data Block Reports
-
- Some reports don't follow the row/column format, however. Instead, some group
- related data in data blocks. A mailing list, for example, typically uses
- several rows for each record: a row for the company name, a second row for
- the street address, a third row for the city, state and ZIP code, etc. In
- such a report all the data for a given customer in the list appears
- in a block. Each block represents a single record even though the data in
- the block spans several rows.
-
- 10.5.6 Data Types
-
- The data type of a field, (string, number, currency, date, Boolean, or memo)
- determines the type of information that can be stored in that field and
- which will print in the report column.
-
- Fields of each data type display on your screen like this:
-
- XXXXXXX String - for example, a company name, account description
- or customer name.
-
- $5,555,555.55 Currency (Paradox/Btrieve files only) - for example $500.00
- or $50,000,000.00-.
-
- 5,555,555.55 Number - for example 120 or 5555.
-
- YYYY-MM-DD Date - for example Oct 10 90.
-
- YES/NO Boolean (YES/NO) data fields - for example, the result of a
- formula which compares a customer's credit limit to see if
- it is greater than $5000 and prints YES if the credit limit
- is more than that amount; NO if it is less than that amount.
-
- XXXXXXX Memo - a paragraph describing a piece of property,
- comments regarding a job applicant, a summary of a movie
- plot, etc.
-
- 10.5.7 Formatting, and Record and Group Selection
-
- While formatting, and record and group selection will be covered in depth
- later, there are a few things about those subjects that are worthwhile to
- cover here:
-
- o Currency, date, and Boolean fields are shown above in the default format.
- This format is used for both the element markers (in the report editor) and
- for the report elements themselves (in the report). If you want your data
- to appear in a different format on your report, you can make the desired
- changes using the Format|Field command.
-
- NOTE: The characters in the element markers change to reflect font changes
- and many formatting changes (alignment, etc.).
-
- o The width and position of a field (when you place it in the Report Editor)
- determines the initial spacing between fields and the order in which the
- fields will print across the report page.
-
- o When you insert a data field in your report, Crystal Reports assumes that
- you want to pull data from all the data records in the selected database.
- To limit the records (or groups of records) used in your report, you need
- to tell Crystal Reports how to identify the records or groups of records
- you want to include. Using Edit Record Selection Formula or Edit Group
- Selection Formula on the Print menu, you can build the selection formula
- that fits your needs.
-
-
- 10.6 Building Your Prototype
-
- To build your report you will follow these steps:
-
- o Select the database(s) you wish to use in your prototype report.
- o Enter and position the data fields, text, and titles you want included
- in the header, footer, and body of your report.
- o Print your report to the Print Window and review your work.
- o Make whatever changes are called for.
- o Insert your totals, subtotals and other group fields.
- o Enter and position any formula fields that will calculate or
- manipulate data or create flags.
- o Print your report to the Print Window and review your work.
- o Format the report elements that you want to stand out in some way from
- the others.
-
- 10.6.1 Selecting the Database(s)
-
- You use the File|New Report command to begin a report from scratch. That
- command leads you to a dialog box from which you can select the first
- database you wish to use. To select additional databases, you use the
- Database|Add File to Report command.
-
- 10.6.2 Entering and Positioning Data Fields
-
- Enter and position data fields using the Insert Database Field dialog
- box that lists available fields in the selected database. Make your
- selections from the list, and then place the field in your report using
- the rectangular field placement cursor that appears.
-
- 10.6.3 Adding Text
-
- You can add text to your report by typing it at the text cursor and then
- moving it into place. Move the I-beam cursor to the line on which you
- wish to enter text and click the left mouse button to set the text cursor
- at the left edge of the Report Editor. Then, simply type in your
- text, move the I-beam cursor in front of it, and push it into position using
- the Tab key or Space Bar. You can also add text by inserting text fields and
- positioning them as you would any other field.
-
- 10.6.4 Entering Field Titles
-
- By default, Crystal Reports automatically inserts a field title whenever
- you insert a new field or formula field. The title is a text field that can
- be edited. The left edge of the title field comes aligned with the left edge
- of the field it identifies. To toggle this feature off you use the
- File|Options command.
-
- 10.6.5 Printing and Reviewing
-
- You can print and review your work in progress at any time using the
- Print|Print To Window command. When you select this command, Crystal
- Reports prints your report to the print preview window.
-
- 10.6.6 Making Changes
-
- Move a database field drag it to a new position with the mouse, or by
- selecting it and using the Arrow keys. You can move a field within
- its originating section or to other sections of your report if you wish.
- To delete a field select it and then press the Delete key or select
- Edit|Clear.
-
- NOTE: To select multiple fields at one time, press the Shift key and,
- while keeping it depressed, click the various fields you want to select.
- Handles will appear on each field selected. When finished, you can
- move or delete the selected fields as a group.
-
- 10.6.7 Placing Totals, Subtotals, and Other Group Values
-
- To place grand totals select the numeric or dollar field you want to total,
- and then select Insert|Grand Total from the Menu Bar.
-
- Select group values (subtotals, group averages, group counts, etc.) by
- first selecting the field you want grouped. Then select the kind of
- group value you want, using the Insert|Subtotal or Insert|Summary commands.
- Select the kind of group value you want (if you selected Insert|Summary).
- Then select the field that the program uses to sort and group your data
- by and the sort direction.
-
- 10.6.8 Moving Group Values
-
- To move a subtotal or summary drag it to a new position with the mouse, or
- select it and move it with the Arrow keys. You can move subtotals and
- summaries only within their originating sections, or from the group footer
- section to the group header section for the subtotal or summary of interest.
-
- 10.6.9 Entering Formulas
-
- Enter formulas using the Insert|Formula command. This command calls up
- the Formula Editor. Using the Formula Editor, build your formula using
- fields, functions, and operators, and check your work using the built in
- formula checker.
-
- 10.6.10 Formatting
-
- You can change the font or point size using the Format|Font command. You
- can change the alignment and printing characteristics of field data using
- the Format|Field command, and you can change the conditions that trigger
- subtotals, add page breaks, suppress blank lines, hide selected sections,
- etc. using the Format|Section command.
-
- Once you have built a prototype report, you have a working model that you
- can customize to meet your specific needs.
-
-
- 10.7 Manipulating the Data with Formulas and Functions
-
- Crystal Reports uses formulas and functions to help you create reports more
- quickly and easily. It uses them also to allow you to do the kind of
- "number crunching" and data manipulations that are necessary for advanced
- reporting.
-
- 10.7.1 Formulas
-
- A formula is a set of instructions that may be used to calculate
- information you can't obtain directly from database data fields.
-
- For example:
- o A database record may have a Qty1 field and a Qty2 field but no field
- that sums both quantities. If you want the sum of these two fields to
- appear on your report, you need a formula that adds the value in one field
- to the value in the other.
-
- o A database record for a sales rep may contain the field GrossSales and
- you want to use 120% of that gross as the sales quota for the following year.
- To accomplish this you need a formula that multiplies GrossSales by 120%.
-
- o A database record for a one product company may contain a field Revenue
- that expresses total dollar sales for the year. You're interested in
- determining the number of units sold based on an average price of 49.95 per
- unit. To accomplish this you need a formula that divides Revenue by 49.95.
-
- All of these examples require simple formulas: {file.Qty1} + {file.Qty2},
- 1.20 * {file.GrossSales}, and {file.Revenue}/49.95 respectively. These
- formulas all use Crystal Reports operators (+, * [multiply], / [divide])
- and they're all easy to create and understand.
-
- But not all of your information needs can be reduced to simple formulas;
- some needs require extensive calculations or manipulations. For example:
-
- o You want to determine your average monthly unit sales for the last year,
- rounded to the nearest unit.
-
- o You want to convert ounces of inventory to pounds and ounces, and have
- it appear in the format x pounds y ounces.
-
- The formulas required to accomplish these activities require a fair amount
- of data manipulation: rounding, averaging, converting numbers to text,
- calculating remainders, etc. While some of the manipulations (averaging,
- calculating remainders) can be done using Crystal Reports operators alone,
- others can't be done without the use of functions. And even the ones that can
- be done without functions can be done more quickly and efficiently with them.
- (For additional information on formulas, see Crystal Reports Help.)
-
- 10.7.2 Functions
-
- A function is a preset procedure or subroutine used to evaluate, make
- calculations on, or transform data. For example:
-
- o the NumericText function evaluates the contents of a text field to see
- if it is a number, and
-
- o the UpperCase function transforms all lowercase characters in a string
- to uppercase.
-
- When you specify a function, Crystal Reports performs the set of operations
- built into the function without requiring you to specify each operation
- separately. For example:
-
- o the Average function sums a list of values and divides the sum by the
- number of values in the list.
-
- o the DayOfWeek function extracts the day component of a date, determines
- the day of the week the date falls on, and converts the day of the week to
- a number (1-7) where Sunday is the first day of the week.
-
- By performing multiple operations with a single command, these kinds of
- functions are a kind of shorthand that make it easier and less time
- consuming for you to create reports.
-
- But not all functions involve lengthy calculations; some simply allow you
- to do things that you couldn't do easily without them while others take the
- drudgery out of report creation. For example:
-
- o the ToNumber function converts a number that has been stored as text,
- to a number that can be used in calculations, and
-
- o TrimRight removes all the spaces to the right of a string of data
- stored left-justified in a database.
-
- 10.7.3 How Functions are Used
-
- Functions are used in formulas. In fact, a single function and its
- required argument(s) may include the entire formula. For example, Abs
- ({file.TestResult}) is a perfectly acceptable, stand-alone formula for
- calculating the absolute value of the field TestResult.
-
-
- 10.7.4 Function Syntax
-
- Each function comes with its own set of usage rules (syntax). These rules
- must be followed for the function to perform correctly. If they are not,
- Crystal Reports displays a Formula Compiler Error message.
-
- As an example, the correct syntax for using the Average([array]) function is:
-
- Average ([array])
-
- << where array is an array of constants, field values or calculation
- results, separated by commas.>>
-
- Translated, this means that to use the Average([array]) function correctly,
- you should enter:
-
- Average
-
- followed by a list of numeric values, separated by commas, with the list of
- values enclosed in brackets, and with the array enclosed in parentheses.
- Thus:
-
- Average ([1,2,3,4,5])
-
- is an example of the correct way to use the Average([array]) function.
-
- If you try to use the function:
-
- o without separating the values by commas,
- o without enclosing the values in brackets,
- o without enclosing the array in parentheses,
- o while including any unnecessary characters, or
- o with values that are not numeric,
-
- Crystal Reports won't accept the formula and will display a Compiler Error
- message identifying your error.
-
- 10.7.5 Entering Formulas and Functions
-
- Formulas and functions are entered via Crystal Reports' Formula Editor.
-
- The Formula Editor is a dialog box that contains all the tools you need to
- create and check the correctness of formulas. Using the Editor, you:
-
- o assign a name to your formula,
- o enter the formula,
- o check it to make sure you have entered it correctly, and then
- o accept it for use in your report.
-
- When you accept it, Crystal Reports places the formula in your report in the
- position you selected for it. Then, when you print the report, Crystal
- Reports prints the results of the formula instead of the formula itself.
-
- 10.7.6 The Fields Box
-
- You can enter fields into your formulas in two ways: via the Fields box, or
- manually.
-
- o To enter a field via the Fields scroll box, you move the I-beam cursor
- to the place you want to insert the field and click the left mouse button to
- set the text cursor at that point. Then you locate the field you wish
- to insert from the Fields scroll box list.
-
- - Fields already in use in the report are grouped at the top of the
- list; other available fields follow.
-
- - Formulas you have entered are listed next, their names preceded by
- the @ sign.
-
- - All other fields available in the active databases are listed
- last, grouped by database.
-
- Select a field. Crystal Reports inserts the selected field (complete with
- the required syntax elements) at the text cursor.
-
- NOTE: You select an item from the Formula Editor scroll boxes (Fields,
- Functions, or Operators) by double clicking it, or by clicking it once to
- highlight it and then clicking the Select button at the bottom of the
- Editor to complete the selection process.
-
- o To enter a field manually, you locate the text cursor in the appropriate
- position and type in the field name as you would any text.
-
- o The correct syntax for a database field name is:
-
- {file.fieldname}
- If you:
-
- - don't include the file name,
- - leave out the separating period, or
- - fail to surround the expression in braces,
-
- Crystal Reports will generate a Formula Compiler Error message detailing
- your error.
-
- o The correct syntax for a formula field is:
-
- {@formulaname}
-
- 10.7.7 Operators and Functions Boxes
-
- You can also enter operators and functions into your formula in one of two
- ways: manually or via the Operators and Functions scroll boxes.
-
- o To enter an operator or function manually, locate the text cursor in
- the appropriate position and type in the operator or function as you would
- any text.
-
- o To enter an operator or function via the lists in the Functions and
- Operators scroll boxes, set the text cursor where you want the entry
- to appear in the formula.
- - Then select the item of interest from the scroll box lists.
- Crystal Reports inserts the selected item in your formula, complete
- with any parentheses, brackets, or commas required.
-
- NOTE: For an array of items, only the first comma is included. As
- you enter additional items into an array, you will need to type in
- commas to separate the items.
-
- 10.7.8 Order of Precedence
-
- When entering formulas that contain different kinds of operators, it is
- important to consider order of precedence, the order in which Crystal
- Reports performs the operations in your formula.
-
- You learned simple order of precedence in high school math: when performing
- calculations, do multiplication and division first, then addition and
- subtraction. Thus:
-
- 5 + 10 X 3 = 35
-
- The calculation 10 x 3 is performed first to get 30. 30 is then added to
- 5 to arrive at the final answer.
-
- Now if your intention is to add 5 to 10 and then multiply the sum by 3,
- you have to modify the order of precedence with parentheses. You can do
- that thus:
-
- (5 + 10) x 3 = 45
-
- It's clear that parentheses have a higher precedence than the add,
- subtract, multiply, and divide operators. They redirect the order of
- calculation.
-
- You learned all of this in school and Crystal Reports follows the same
- rules of precedence. But Crystal Reports uses many additional operators,
- and it's important for you to understand the precedence Crystal Reports
- assigns to each so you can write your formulas to perform as expected.
-
- o In the following list, Crystal Reports performs the top level operations
- first, then the second level, then the third, and so forth.
-
- o When it encounters two or more operations that are on the same level,
- it performs them left to right.
-
- Level 1 Parentheses, Array, IfThenElse
- Level 2 Call, Subscript
- Level 3 Identity, Negate, Dollar, Not
- Level 4 Multiply, Divide, Percent
- Level 5 Add, Subtract
- Level 6 To
- Level 7 Less than, Greater than, Greater than or equal, Less than
- or equal, In
- Level 8 Equal, Not equal
- Level 9 And
- Level 10 Or
-
- 10.7.9 Using Dates in Formulas
-
- Crystal Reports includes many useful functions for including dates and
- date ranges in formulas; you will learn more about those functions in
- Crystal Reports Help. At this point, however, it's useful to know how to
- enter any date into a formula.
-
- You enter a date simply by entering the Date function (manually or via the
- Function button) and then providing the date of interest in the parentheses
- that follow in the form YYYY,MM,DD (1992,01,01 = January 1, 1992).
-
- 10.7.10 The Formula Checker
-
- The Formula Editor also contains a formula checker which checks the syntax
- of your formula. If the syntax is incorrect, the formula checker points out
- the location of the problem and tells you what the problem is. You activate
- the formula checker by selecting the Check button. Crystal Reports also
- checks the formula automatically when you choose Accept. When debugging
- formulas, especially if you have entered them manually, look carefully for:
-
- o missing quotation marks around text strings,
- o missing database name accompanying field names,
- o missing braces around database name/field name combinations,
- o missing closing parentheses to match opening parentheses,
- o case differences (the Formula Checker is case sensitive),
- o if-then-else formulas that use different data types for the then and
- else actions, and
- o using X instead of * for multiplication.
-
- The Formula Editor is easy to use and can be called up by selecting Formula
- from the Insert menu.
-
- 10.7.11 Developing Complex Calculations with Formulas
-
- Crystal Reports allows you to combine fields, functions, and operators to
- create complex calculations and manipulations of data. For example, to test
- the drawing power of two different offers, you can use a single Crystal
- Reports formula to send one offer to all customers with an even customer
- number and a second offer to all customers with an odd customer number. You
- can do some remarkable manipulations using Crystal Reports formulas.
-
-
- 10.8 Grouping, Summarizing, and Sorting Your Data
-
- Crystal Reports allows you to group, summarize, and sort your data to
- achieve the reporting results you want.
-
- 10.8.1 Grouping the Data
-
- A group is a set of records that are related to each other in some way.
- In a customer list, for example, a group could consist of all those
- customers living in the same ZIP code, or in the same state. In a sales
- report, a group could consist of all the orders placed by the same customer,
- or all of the orders generated by a specific sales rep.
-
- Breaking data into groups (and then doing something to evaluate the group
- data, if you wish) is a key part of effective reporting. In fact, it's what
- separates a report from being merely a presentation of raw data and a
- valuable communication tool.
-
- Crystal Reports allows you great flexibility in grouping data. It also
- gives you the ability to create a number of different kinds of group values.
-
- 10.8.2 Group Values
-
- A group value is the value generated as the result of an evaluation, a
- tally, or a calculation performed on data from a single group. A subtotal
- is one kind of group value; it is the sum of all of the values from a single
- field, from all the records in a group. In a sales report, for example, if
- you subtotal sales by sales rep, Crystal Reports gathers all the records
- that belong to the sales rep and totals the sales amounts from all the
- records. In a group average, Crystal Reports averages the values in a group
- of records; in a group count, it counts the values in a group of records,
- etc. Group values are important tools for creating powerful reports.
- Crystal Reports gives you several alternatives for working with group data.
- It enables you to:
-
- o calculate the sum of values,
- o calculate the standard deviation or variance of the values,
- o average the values,
- o count the values,
- o determine the highest value, and
- o determine the lowest value in the group.
-
- 10.8.3 Grouping Data with Crystal Reports
-
- While there may be many data fields on a report, there is typically only
- one field for which you are interested in grouping the data. In a sales
- report, for example, it would probably be the field listing the amount of
- sales; in a commission report, it would probably be the field listing the
- amount of commission, etc. To group data you first select the field you
- want to group together.
-
- Once the field is selected, you select the action you want to take on each
- group of data from that field:
-
- o If you want to simply group the data and take no further action, you
- can select Insert|Group.
- o If you want to subtotal it, you can select Insert|Subtotal.
- o If you want to average, count, determine the maximum or minimum value,
- etc., you can select Insert|Summary.
-
- Subtotals and summaries make up the category of group fields.
-
- NOTE: The Insert|Subtotal command is simply a shortcut for setting up
- a summary that adds the values in each group.
-
- Once you have selected the group field and the action, you select another
- field (a sort and group by field) that triggers a grouping whenever its
- value changes. In grouping your data by state, for example, you would use
- the state field to create a new group (and generate a group value if
- selected) whenever the state changes. Likewise, the ZIP code field would
- trigger a grouping whenever the ZIP code changes.
-
- Once you've made these simple selections, Crystal Reports does the rest.
- Your data will be grouped, and the group value (if you have selected one)
- will be calculated and will accompany each group.
-
-
- 10.9 Summarizing the Data
-
- Crystal Reports provides three easy-to-use summarizing options:
-
- Grand Total A grand total adds all values in a field for the entire
- report and prints the sum on the last page.
-
- Subtotal A subtotal is a partial total, a total of a specific,
- limited group of data in a field.
-
- Summary A summary summarizes field data from a specific, limited
- group of records. It can total the data like a subtotal,
- but it can also average the values, count the values, or
- determine the highest or lowest value in each group or field.
-
- All of these options are available on the Insert menu.
-
- 10.9.1 The Summarizing Process
-
- The process of summarizing the data on your report follows these steps:
-
- 1. Selecting the field you want to summarize.
-
- 2. Selecting the summarizing option you want from the Insert menu.
-
- Finally, if you select Subtotal or Summary as a total type, the
- process will also include the following step:
-
- 3. Selecting the data field that triggers a new subtotal/summary
- whenever its value changes.
-
- 10.9.2 Selecting a Field to Total
-
- To select the field you want to summarize, click on it with a mouse.
- Crystal Reports puts handles on the selected marker to highlight it as
- selected.
-
- 10.9.3 Selecting a Total Type
-
- To select a total type, select it from the Insert menu or pop-up menu.
-
- 10.9.4 Selecting a Field to Trigger a New Subtotal
-
- If you select Subtotal or Summary as a total type, Crystal Reports asks
- you to indicate the field that is to trigger a new subtotal/summary
- whenever its value changes.
-
- NOTE: For additional information on subtotaling data (with examples),
- please see section 11.2.32 entitled "Sorting Your Data."
-
-
- 10.10 Sorting
-
- There is a logic to the way values are arranged when they appear in a
- column on your report. Initially, they are arranged in the same order as
- the data appears in your database. But data can be sorted in a variety of
- ways:
-
- o A mailing list, for example, could be sorted in ascending order, on
- the ZIP code field; that is, the customers would be sorted so that those
- with the lowest ZIP codes would appear first and those with the highest
- ZIP codes would appear last.
-
- o It could also be sorted in ascending alphabetical order, on the last
- name field; that is, customers with last names beginning with A would
- appear first and those with last names beginning with Z would appear last.
-
- o It could also be sorted by street address or customer first name if
- you had some practical reason for doing so.
-
- Crystal Reports gives you the opportunity to change the existing sort order
- using the Print|Record Sort Order and Print|Group Sort Order commands.
-
- 10.10.1 Sorting by Record
-
- When you use the Print|Record Sort Order command, Crystal Reports asks you
- to select two things:
-
- o the field you want your sort to be based on (sort field), and
- o the sort direction.
-
- 10.10.2 Sort Field
-
- A sort field is a field that determines the order in which data appears on
- your report. Crystal Reports sorts field data using Windows' sort
- comparison algorithms, and it uses rules specific to the Country you
- select in the International section of the Windows Control Panel.
-
- You can use any field as a sort field. A field's data type determines the
- method in which the data from that field is sorted:
-
- Text Text fields are sorted in the following manner:
- One character values are sorted so that blanks have the
- lowest value, then punctuation, then numbers, then
- uppercase letters, and finally lowercase letters.
- Then two character values are sorted, then three, etc.
- using the same rules. As a result: "BOB" comes before "bob",
- "123" comes before "124", " " (blank) comes before "a",
- and "aa" comes before "aaa"
-
- Dollars Dollar fields are sorted in numeric order.
-
- Number Number values (120, or 5555) are sorted in numeric order.
-
- Dates Date fields are sorted in chronological order.
-
- Booleans Comparison fields are sorted so that false values come
- first, then true.
-
- When you select a sort field, Crystal Reports sorts the values from
- that field.
-
- 10.10.3 Sort Direction
-
- Direction refers to the order in which the values are printed, once sorted.
-
- o Ascending order means smallest to largest, 1 to 9, A to Z, False to True.
- o Descending order means largest to smallest, 9 to 1, Z to A, True to False.
-
- 10.10.4 Single Field Sorts
-
- Single field sorts are sorts in which all the data in the report is sorted
- based on the values in a single field. Sorting an inventory report by stock
- number and sorting a customer list by customer number are examples of single
- field sorts.
-
- 10.10.5 Multiple Field Sorts
-
- In multiple field sorts, Crystal Reports first sorts the entries
- (alphabetic or numeric) in the first field selected, putting them in
- ascending or descending order as specified. Then it sorts any entries in
- the second field that can be sorted without disturbing the sort order of
- entries in the first field. It then sorts any entries in the third field
- that can be sorted without disturbing the sort order of the entries in the
- first two fields. It follows the same pattern for sorting additional fields.
-
- 10.10.6 Sorting Groups
-
- Crystal Reports allows you to change the order in which groups appear on
- your report. You can:
-
- o base the sort on any group (subtotal or summary) in your report, and
- o sort your report so that group field values appear in ascending or
- descending order.
-
- You change the sort order using the Print|Group Sort Order command. When
- you sort by group, nothing happens to the sort order of the records within a
- group; only the relative positions of the groups themselves change.
-
- NOTE: For additional information on sorting and examples of single field,
- multiple field, and group sorts, please see section 11.2.32 entitled
- "Sorting YourData."
-
-
- 10.11 Editing and Formatting the Data
-
- Crystal Reports makes it easy to edit and format your data. The
- editing/formatting process follows these steps:
-
- 1. Selecting the data you want to edit or format.
-
- 2. Selecting the editing or formatting action you want to take place.
-
- 3. Entering the specifics of the action in the dialog box/editor
- if/when it appears.
-
- 10.11.1 Selecting the Data
-
- To select the data element you want to edit or format, you click on it
- with your mouse. Crystal Reports draws handles on the element marker to
- highlight it as selected.
-
- 10.11.2 Selecting the Action
-
- Once the element is selected, you select the editing or formatting action
- from Crystal Reports' Edit or Format menus. For example:
-
- o to change the font used to print the data, select Font from the Format
- menu,
- o to hide the field when printing, select Field from the Format menu, or
- o to modify a formula, select Formula from the Edit menu.
-
- 10.11.3 Entering the Specifics
-
- In those cases where a dialog box or editor appears after you've selected
- an action, you enter the specifics of that action in the window that appears.
- For example:
-
- o in the Font dialog box, you enter the font and point size you wish to
- use, and indicate whether you want the data to appear in boldface or italics,
- or whether you want it to be underlined or overprinted with the strikeout
- character, and
-
- o in the Formula Editor, you make the changes you want to the formula that
- appears, check those changes if you wish, and accept the revised formula
- when you're finished.
-
- Crystal Reports takes it from there and performs the action you selected.
-
- NOTE: In some cases you have to specify a second action to complete the
- editing change desired. For example, to move some text in your report, you
- first cut the text from its current position, and then you paste it in its
- new position. In such a case you select the data and then the action (Cut)
- to cut the text to the clipboard. Then you mark the new position using the
- insertion pointer and select Paste to insert the text in the new position.
-
-
- 10.12 Specifying Records/Groups to be Included
-
- When you select a field to appear on your report, Crystal Reports, by
- default, prints field values from every record in the selected database.
- But in many cases you may not want to include all the values, but only a
- specific range of values. For example, you may want to include only a
- specific group of customers or a specific range of account numbers out of
- the total number of values in the database. Or you may want to include
- values from only those records that fall within a particular date range.
- With Crystal Reports this is easy. The program includes four commands on the
- Print menu for restricting your report to specific records or groups of
- records as described in the following sections:
-
- 10.12.1 Select Records
-
- This option allows you to limit your report to specific records that fit a
- condition or conditions you specify. It automatically builds a record
- selection formula using your responses to dialog box questions. This option
- requires no knowledge of the Crystal Reports formula language.
-
- 10.12.2 Edit Record Selection Formula
-
- This option also allows you to limit your report to specific records that
- fit a condition or conditions you specify. It takes you to the Formula
- Editor where you can manually build a record selection formula to fit
- your needs. This command is intended for users who are familiar with the
- Crystal Reports formula language.
-
- 10.12.3 Select Groups
-
- This option allows you to limit your report to specific groups that fit a
- condition or conditions you specify. It automatically builds a group
- selection formula using your responses to dialog box questions. This
- option requires no knowledge of the Crystal Reports formula language.
-
- 10.12.4 Edit Group Selection Formula
-
- This option also allows you to limit your report to specific groups of
- records that fit a condition or conditions you specify. It takes you to
- the Formula Editor where you can manually build a group selection formula
- to fit your needs. This command is intended for users who are familiar with
- the Crystal Reports formula language.
-
- You select the command, specify the records or groups of records you want
- included, and your report prints using only the selected records or groups.
-
-
- 10.13 Printing the Finished Report
-
- When you want to print your report or when you want to see what your report
- will look like when printed, use Crystal Reports' three printing options:
-
- o printing to the printer for hard copy output
- o printing to a print window to review your work
- o printing to a disk file for use with other applications
-
- All of these options are available on the Print menu.
-
- When you are creating a report, you will find yourself printing to the
- print window often, in order to check placement and formatting of the
- various report elements. The print window even includes a print preview
- function that lets you see each page of your report as a whole, top to
- bottom. Then, when you want to print a final or interim copy of the report
- for hands-on review, you can print to the printer for hard copy output.
-
- If you want to use your report data in another application (in a spreadsheet
- or word processor for example), you can print the report to a disk file in
- any of a variety of popular file formats. Once in a disk file, you can import
- the data into your other application following the importing procedures
- established by the receiving application.
-
-
-
