UBL-CR-263In your invoicing software
A UBL invoice should not include the AccountingCustomerParty AccountingContact
This is the rejection, word for word: „[UBL-CR-263] Your invoice contains an AccountingContact element in the AccountingCustomerParty which is not allowed in EN16931 invoices. This element must be removed.“
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:AccountingContact` element from your Invoice (UBL-CR-263).
If you enter it yourself in your invoicing software
Before
<cac:AccountingCustomerParty> <cac:AccountingContact>value</cac:AccountingContact> </cac:AccountingCustomerParty>
After
<cac:AccountingCustomerParty> <!-- cac:AccountingContact removed for EN 16931 compliance --> </cac:AccountingCustomerParty>
Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-263.
