UBL-CR-094In your invoicing software

A UBL invoice should not include the ContractDocumentReference CopyIndicator

This is the rejection, word for word: „[UBL-CR-094] Your invoice contains ContractDocumentReference/CopyIndicator 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:CopyIndicator` element from your Invoice (UBL-CR-094).
If you enter it yourself in your invoicing software
Before
<cac:ContractDocumentReference>
  <cbc:CopyIndicator>value</cbc:CopyIndicator>
</cac:ContractDocumentReference>
After
<cac:ContractDocumentReference>
  <!-- cbc:CopyIndicator removed for EN 16931 compliance -->
</cac:ContractDocumentReference>

Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-094.
