Hey I'm newbie to Pega PRPC, Sorry if my question is very silly.
How does once any case reach an assignment, Assign- AddAssign activity gets called? Where can i see the configuration of calling the Assign- AddAssign activity? Or it happens internally within Pega and we should get to know about it only by experience?
You don't need to call this activity as Pega automatically calls it based on your Case Lifecycle design. If you are creating your own Activity rule and need to add a new assignment, you can then use the "Call" method to call the AddAssign activity.
