Logic to RAISE BUS1001006 CREATED event

Can anyone shed some light on where the logic could be which raises this event for material creation workflow? I have already checked SWEC and there is no entry for MATERIAL and a CREATED event so I know it is not getting done from there. I have searched for the workflow related function modules which raise events in the MM01 main program 'SAPLMGMM'. I've also searched for the business object BUS1001006 with no luck. Any suggestions on how to find where this event is being raised?

Thanks,

D.
