I was checking SWE2 for knowing the event receiver for a particular Business object and it's event. there i found
BO - BUS2042
Event - TO_BE_APPROVED
Receiver - SWE_EVENT_CREATE
The Receiver here is not any WF or task.. If any WF or task have any event linkage that we can check in PFTC -> Start Event or in swe2
But in this case where we can Check that this BO event is Linked with this FM.
