See if PO is not already processed and other documents are created out of it. If so then you wont be able to change it.

Goto backend and try to change PO manually to see exact text of error message.

Hi Mahesh,

It seems a data issue, Similar PO might be changed already and thus in SAP it is not allowing to change.

So try changing the test data and post the IDOC again , it will change the PO .

Can you ask abap team to check for the Same PO and try to change it in thier system directly without using PI interface.

See if they get the same message, if yes then ABAP team has to check from there side for any program errors.
