About When Condition rulesPurpose
A when condition rule evaluates a Boolean logical statement involving comparisons among values of properties, to return true or false.
Where referenced
Rules of many other rule types can reference when condition rules. For example, you can reference when condition rules in activities, flows, and through the <pega:when > JSP tag in HTM and XML rules.
Access
Use the Application Explorer to access when condition rules that apply to the work types in your application. Use the Records Explorer to list all when condition rules available to you.
Development
Many when condition rules can be conveniently expressed as one or more Boolean expressions (comparisons or function calls) ANDed or ORed together. Use the Conditions tab to enter or update such rules. Other when condition rules require more complex logic to combine the Boolean expressions. Use the Advanced tab to enter or update those rules.
Delegation
C-494 KHATV 10/22/03 After initial development and testing, selected when condition rules can be maintained by line business managers rather than by application developers. The Conditions tab of the form provides managers access to the fields most often updated. The Options area on the Advanced tab is not available to these users.
For each when condition rule 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.
