See the below SWE2 config for ISUPARTNER BO, we are handling the event in a method within a custom class and it's triggering without any issues even with Receiver Type left as blank except for the following scenario:
"In the Service Cloud, a move out is triggered by adding a new address, flow comes to ISU-ECC, the new address for the BP gets updated in the ISU side but the delta replication doesn't get triggered to send the updated address back to Service Cloud to be replicated in BP."
I am not even sure what should we put in the Receiver Type field for this if we have to.
