UBL-CR-201In your invoicing software
A UBL invoice should not include the AccountingCustomerParty...
This is the rejection, word for word: „[UBL-CR-201] Your invoice contains a CustomerAssignedAccountID element in the buyer section 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 `cbc:CustomerAssignedAccountID` element from your Invoice (UBL-CR-201).
If you enter it yourself in your invoicing software
Before
<cac:AccountingCustomerParty> <cbc:CustomerAssignedAccountID>value</cbc:CustomerAssignedAccountID> </cac:AccountingCustomerParty>
After
<cac:AccountingCustomerParty> <!-- cbc:CustomerAssignedAccountID 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-201.
