How to prevent supplier from requesting to cancel PO lines

Hi,

Please advise if there is another way to prevent suppliers from requesting to cancel PO lines as appose to OAF personalisation.

Only a request to cancel an entire PO will be allowed.

We used personalisation as follows:

Navigate to: iSupplier Portal > Orders tab > Purchase Orders > Select PO > Select Request Cancellation button > Scroll down to the PO lines > Select "Show" on a PO line

Personalisation on page /oracle/apps/pos/changeorder/webui/PosChangePOPG:

Remove "Action" column for shipment line cancellation request:
Select "Rendered: false" for "Column: (PosActionSwrCol)"

Remove "Reason" column for shipment line cancellation request:
Select "Rendered: false" for "(Column: (PosLineReasonSwrCol)"
