UBL-CR-132In your invoicing software
A UBL invoice should not include the AdditionalDocumentReference IssuerParty
This is the rejection, word for word: „[UBL-CR-132] Your invoice contains AdditionalDocumentReference/IssuerParty 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 `cac:IssuerParty` element from your Invoice (UBL-CR-132).
If you enter it yourself in your invoicing software
Before
<cac:AdditionalDocumentReference> <cac:IssuerParty>value</cac:IssuerParty> </cac:AdditionalDocumentReference>
After
<cac:AdditionalDocumentReference> <!-- cac:IssuerParty removed for EN 16931 compliance --> </cac:AdditionalDocumentReference>
Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-132.
