UBL-CR-117In your invoicing software

A UBL invoice should not include the AdditionalDocumentReference LocaleCode

This is the rejection, word for word: „[UBL-CR-117] Your invoice contains AdditionalDocumentReference/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 (UBL-CR-117).
If you enter it yourself in your invoicing software
Before
<cac:AdditionalDocumentReference>
  <cbc:LocaleCode>value</cbc:LocaleCode>
</cac:AdditionalDocumentReference>
After
<cac:AdditionalDocumentReference>
  <!-- cbc:LocaleCode 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-117.
