Reversing Event in TM

Dear Expert ,

POD event is already reported in TM and propogated from EM and execution status is changed to "executed " from "In Execution " .

We want to reverse execution status and delete POD event . After that we want to send shipment to ECC to create shipment . Then again , we want to report POD event back to TM .

Please suggest .

I tried to run "REVOKE_EVENT" action for POD event  in EXECUTIONINFORMATION node , it did not worked . I am just wondering how REVOKE_EVENT action work and what is does ?

Thanks in Advance .

Regards,
