You can configure Pega Fulfillment Control Center for Communications to retrieve product class information at run time to select the correct flow and class names. You do this by implementing dynamic class referencing by using declarative pages and decision tables.
Open the DetermineAppExtensionClass decision table rule in the UPlus application ruleset. On the Table tab, change the Organization to UPlus and update the return value to PegaComm-FW-FCFW-Data-AppExtension.
In the AppExtension data transform rule, on the Definition tab, set the properties for the dynamic class referencing functionality to that of the implementation layer application class names, work queues, and so on.
