workflow not starting in QA

Hi,

I have created and tested WF in DEV but after transporting to QA, WF in not starting in QA. I ran SWU_OBUF and WF_BATCH is also available in QA.

I checked SWETYPV and link is active there.

I have used SAP_WAPI_CREATE_EVENT for the WF. This FM is also giving success message but WF is not starting.

I have used 2 versions of workflow in DEV (version 0000 and 0001, with version 0001 as active) and after transport, in QA as version 0000. The WF is same in QA and DEV.

Please help me with the issue.

Thanks

Aamir
