ERS PO DELETION

DEAR ALL,

I AM UNABLE TO DELETE THE ERS ACTIVATED PO. IT IS SHOWING THE SATDARD SAP ERROR MESSAGE ME867 AND MEPO000. I CREATED THE PO WITH ACTIVATING ERS AND GR-BASED IV. AFTER THAT I DID GRN . ONCE I REVERSE GRN AND TRIED TO DELETE THE PO IT IS SHOWING THIS ERROR MESSAGE THAT HEADER IS FAULY. I EVEN TRIED DEACTIVATING ERS AND TRIED TO DELEATE . BUT IT IS SHOWING THE SAME ERROR. HENCE REQUESTING YOU TO SUGGEST THE SOLUTION FOR THIS.

THANKS AND REGARDS
