UBL-CR-311In your invoicing software

A UBL invoice should not include the TaxRepresentativeParty PostalAddress...

This is the rejection, word for word: „[UBL-CR-311] Your invoice contains a PostalAddress BuildingName element in the TaxRepresentativeParty 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:BuildingName` element from your Invoice (UBL-CR-311).
If you enter it yourself in your invoicing software
Before
<cac:PostalAddress>
  <cbc:BuildingName>value</cbc:BuildingName>
</cac:PostalAddress>
After
<cac:PostalAddress>
  <!-- cbc:BuildingName removed for EN 16931 compliance -->
</cac:PostalAddress>

Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-311.
