UBL-CR-286In your invoicing software

A UBL invoice should not include the PayeeParty PartyLegalEntity HeadOfficeParty

This is the rejection, word for word: „[UBL-CR-286] Your invoice contains a HeadOfficeParty element in the PayeeParty PartyLegalEntity 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 `cac:HeadOfficeParty` element from your Invoice (UBL-CR-286).
If you enter it yourself in your invoicing software
Before
<cac:PartyLegalEntity>
  <cac:HeadOfficeParty>value</cac:HeadOfficeParty>
</cac:PartyLegalEntity>
After
<cac:PartyLegalEntity>
  <!-- cac:HeadOfficeParty removed for EN 16931 compliance -->
</cac:PartyLegalEntity>

Element order is part of the rule: if the element sits in the wrong place, the validator rejects with UBL-CR-286.
