Find Source of event triggering

Question

Hi all,
I have a doubt in Workflow.
A Workflow can be triggered by an event of the Business Object. But this can be done through
1) Create Event SWUE
2) Simulate Event SWU0
3) Actual action in Tcode which triggers the event
4) Custom program where we use Function Module to trigger event
5) Directly executing function module SWE_Event_Create
6) SWUS u2013 Execute Workflow
7) SWIA u2013 Execute Workflow without Agent
But if event linkage (SWETYPV) is active and once the Workflow is triggered (as seen in SWI1) u2013 how can we find out by what way (of the above mentioned options) the event has been triggered? i.e. how to find out the source of event triggering?

Hi,
I am not sure if you can find the information. I suppose you have investigated the workflow container carefully?
Then you could check all the WF database tables that are updated when the work item is created. For example check SWWWIHEAD table if there is some information about the creator (which program created it). If you can find the information, then you can easily enhance your workflow / business object / whatever to get the information.
Then you could also check if you can get the information with the check function module (that is defined in SWETYPV). Put a breakpoint there, and see if the sy-<field> system variables include some information about the triggering program (perhaps sy-repid?). If you can find some suitable variable, then you could perhaps develop something based on the check function module.
