A Decision Point Activity, or DPA, intelligently routes work items through a process flow based on both the rules you configure and the information in a work item.
Before creating a DPA, you need to know:
What actions you want the DPA to take.
Base the DPA rules on variables in your work items. For example, a DPA might determine which activity to send a biographical data work item to, based on whether an age variable in the work item matches a value specified in one of the DPA’s rules.
What work item properties are available for the DPA in the process flow or subflow.
The DPA can retrieve the properties within a work item and examine its Stored Procedure execution.
