What does UBL-CR-270 mean? A UBL invoice should not include the PayeeParty IndustryClassificationCode

Why did my invoice fail UBL-CR-270?

EN 16931 restricts the UBL vocabulary to the elements that map to its semantic model, and cac:PayeeParty/cbc:IndustryClassificationCode is not one of them. The Payee (BG-10) only carries name, identifier and legal registration identifier, so an industry classification code on the payee should not appear in a compliant invoice.

Official rule text

A UBL invoice should not include the PayeeParty IndustryClassificationCode

Common causes

Invoice generated from a generic UBL 2.1 template that populates every available party field
ERP export copying the full company master-data record (including industry/NACE code) into the PayeeParty block
Reusing a supplier-party mapping for the payee without trimming it to the EN 16931 subset

How do I fix it?

<cac:PayeeParty>
  <cac:PartyIdentification><cbc:ID schemeID="0088">4035011000112</cbc:ID></cac:PartyIdentification>
  <cac:PartyName><cbc:Name>Payee Ltd</cbc:Name></cac:PartyName>
</cac:PayeeParty>
