Easy access to proposition-related rules when creating change requests in revision management
Valid from Pega Version 7.2.1
When selecting propositions for change requests in Decision Strategy Manager, you can view the proposition filter, strategy, and when rules that are associated with the decision data the selected propositions belong to. In addition, you can include those rules in change requests. To view and add any associated rules to a change request, the rules must be part of the application overlay. With the ability to view and select all proposition-related data, you can consistently revise not only propositions themselves but also all associated rules.
For more information, see Proposition-centric revision management functionality.
