UBL-CR-609In your invoicing software

A UBL invoice should not include the InvoiceLine Item AdditionalItemProperty...

This is the rejection, word for word: „[UBL-CR-609] UBL 2.1 Invoice schema does not include `cac:Item/cac:AdditionalItemProperty/cbc:NameCode`. This element must be removed for EN 16931 compliance.

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:NameCode` element from your Invoice.
If you enter it yourself in your invoicing software
Before

  <cbc:NameCode>value</cbc:NameCode>
</cac:AdditionalItemProperty>
After
<cac:AdditionalItemProperty>
  <!-- cbc:NameCode removed for EN 16931 compliance -->
</cac:AdditionalItemProperty>

Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-609.
