This can be b'coz of Check purch.order no is active (A - Check whether the purchase order number already exists) in your sales doc type (TCode VOV8) used for the transaction.

So, if for your business process, one PO number can be mention in more than one sales orders. Then maintain Check purch.order no should mention as <Blank> - No Check under your sales doc type used for transaction's General Control. Or else use diff. PO Number.

Hope this can assist you.

Thanks & Regards

We are not using same PO for diff SO's. I am get this error when a SO change IDoc comes. System is assuming new PO has come in but in reality its changes to existing PO for which a SO exist.

Thanks againf for your help..I will let you know once I test it.
