Purpose

Use a decision table to derive a value that has one of a few possible outcomes, where each outcome can be detected by a test condition. A decision table lists two or more rows, each containing test conditions, optional actions, and a result.

At runtime, the system evaluates the rows starting at the topmost row:

Where referenced

Rules of four other types can reference decision tables:

Access

Use the Application Explorer to access decision tables that apply to work types in your application. Use the Rules Explorer to list all the decision tables available to you.

Development

When creating a rule that is to return only one of a small number of possible values, complete the Results tab before the Table tab.

Delegation

After you complete initial development and testing, you can delegate selected decision tables to line business managers. The Table tab of the Decision Table form provides managers access to the fields most often updated.

TipFor each decision table in your application, consider which business changes might require rule updates, and whether to delegate the rule to non-developers who then can make such updates directly. See How to build for change.
