UBL-CR-051In your invoicing software
A UBL invoice should not include the DespatchDocumentReference Xpath
This is the rejection, word for word: „[UBL-CR-051] Your invoice contains DespatchDocumentReference/Xpath which is not allowed in EN16931 invoices.“
What to have readyNothing. The file has to be re-exported from your invoicing software; we check it again afterwards.
What we doInvoice Navigator automatically removes the disallowed `cbc:XPath` element from your Invoice (UBL-CR-051).
If you enter it yourself in your invoicing software
Before
<cac:DespatchDocumentReference> <cbc:XPath>value</cbc:XPath> </cac:DespatchDocumentReference>
After
<cac:DespatchDocumentReference> <!-- cbc:XPath removed for EN 16931 compliance --> </cac:DespatchDocumentReference>
Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-051.
