Workflow not triggering from SWE_EVENT_CREATE

Hi,

I have created a sample workflow and mentioned start event in basic data  from a custom BO and activated it.

My custom BO has key field workitem id, for which i am passing GUID(some key)

Now when i try to trigger workflow through SWE_EVEN_CREATE from custom FM, workflow is not triggering.

can u please tell me where to check for the logs and what could be the reason.

Thanks,

Krish
