EPMDocument event handling

Hi Guys,

I have a question on EPMDocument event handling in Windchill.

Whenever a collection of EPMDocuments(family table or independent objects) are checked in to Windchill from the Workspace, in OOTB, which Listener services triggered for this event.

I want the list of files from Windchill codebase that are involved in this event handling service.

Does the solution available in any PTC reference guides?

Thanks in advance.
