Once you have chosen the groups for your report and returned to Report View you will see that extra headers and footers have been added for the groups. These group headers and footers are named after the fields they have been based on. The group headers are placed between the page header and the details section, and the group footers are placed between the page footer and the details section. The first or primary group header is placed above the secondary group header, and so on for any other group headers. The primary group footer is placed below the secondary group footer, and so on for any other group footers.
The group headers cause the report to display the value for each of the groups at the head of each group. The same is true for any secondary groups that are contained (nested) within the primary groups. Each of the values from a group field can be said to act as a title for its own group section. You may wish to display the labels that accompany the group fields. Switch to Print Preview to get a clearer idea of the effect of grouping.
In the Detail section the report automatically displays all of the fields from the underlying table. Since for a grouped report the values from one or more of these fields will appear at the head of each group, you may want to delete some of the fields in Detail.
In the group footers and the report footer, there are displayed several summary fields: the first Character field from the underlying table is counted and all the Numeric fields are summed. Thus each grouped section has its own summary information. This applies to the secondary and lower level groups, as well as the primary ones. You may want to delete some or all of these, or add others. Similarly, the Report Footer contains summary information for the whole of the report, and can also be edited.
You can easily relocate fields within the sections by clicking and dragging.
The default report layout is designed to contain enough information to make subsequent editing easier for you. For instance, it is much easier to delete the fields you don’t want and to relocate the remaining fields, than to have to insert fields that are not displayed.
