Request did not validate successfully with DTD. Error: Element InvoiceDetailOrder content does not follow the DTD
The supplier account number in the contract passed in the invoice does not match any active contract in Coupa.
In a Coupa invoice, the contract's supplier account number does not match any active contract in Coupa.
How do I fix it?
If your contracts don't match, Coupa will create the invoice as a draft. A Coupa representative will then assign the appropriate account string and approve it.
