Linking through fields

One of the most powerful features of Ability is the capacity for a field in one document or application to refer to a field in any other Ability document or application. Such a relationship is called linking and can take two forms: one-way linking and two-way linking:

  1. A one-way link (see One-way links) is used to access data that is located in another document, from the current document. The data can be displayed or used in a formula, but cannot be changed unless you open the original document. A one way link can be made between documents in different applications.

  2. A two-way link (see Two-way links) allows you to change data at either end of the link. This means that the original document is updateable from the target document, though two-way links cannot be used in formulas.

Linking can be used to connect these documents:

For a general discussion on fields, see Fields - an introduction.

Links can also be set up between cells in the same spreadsheet or fields in the same Write or database document (see One-way links in a spreadsheet and Two-way links in a spreadsheet).
