Request did not validate successfully with DTD

The supplier is sending a cXML invoice to Coupa that is not properly formatted.

How do I fix it?

Try the following:

  • The supplier should check the validity of the XML specifications they are sending to Coupa. They can do this by POSTing to the Document Type Definition (DTD) of the specification.
  • The supplier may have created an invoice against an order number that doesn't exist in the system.
