Unable to trigger workflow on status NOPR in tcode iqs1.

I have created ZBUS7050 business object by using standard BUS7050. I have created custom workflow . I want workflow to be triggered when the status is NOPR in tcode iqs1.

I have done configuartion in bsvw and swetypv . But workflow is not triggering . I am not able to trigger function module SWW_WI_CREATE_VIA_EVENT_IBF.
