UBL-CR-030In your invoicing software
A UBL invoice should not include the BillingReference LocaleCode
This is the rejection, word for word: „[UBL-CR-030] Your invoice contains BillingReference/LocaleCode 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:LocaleCode` element from your Invoice.
If you enter it yourself in your invoicing software
Before
<cac:InvoiceDocumentReference> <cbc:LocaleCode>value</cbc:LocaleCode> </cac:InvoiceDocumentReference>
After
<cac:InvoiceDocumentReference> <!-- cbc:LocaleCode removed for EN 16931 compliance --> </cac:InvoiceDocumentReference>
Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-030.
