Hi,
Could someone explain the reason for receiving the following error message when trying to add attachments to the PO No Part Lines.

Service: DocReferenceObject
Source LU Name:PurchaseRequisition
Transformation Method: REQUISITION_NO
Error Text: Field [KEY_REF] is mandatory for category and requires a value
