Invalid order/document reference. Could not find order header XX, order line num XX
An invoice line is missing from a Coupa PO.
The Invoice is PO backed (based on PO#/Supplier) but an Invoice line passed cannot be found on the Coupa PO.
How do I fix it?
Forward the invoice to the supplier team for confirmation of the extra PO line.
Search for the PO# in the Coupa instance and confirm the extra PO line with the information from the cXML Error Notification.
