It means that you are trying to update a requisition that is already attached to a PO.
If you are on R12, go to the Buyer workcentre, press distributions tab and search by the requisition number that is causing the issue.
You should get the related PO number.
Is there any base line table to get the Information for the Corresponding PO related to the Requisition Number?
Thanks for your help
From PO side, take a look into po_distributions_all table
Columns req_header_reference_num, req_line_reference_num and req_distribution_id contains the requisition information for that PO.
If the requisition you are trying to update exist in this table, you get the error.
I hope it helps,
Thanks for the response.
I checked the po_distributions_all for the above Requisition Reference bu unable to find any related records.
select * from po_requisition_headers_all where segment1='Test001'(I could not find any corresponding records in the PO table)
