What does UBL-CR-608 mean? A UBL invoice should not include the InvoiceLine Item AdditionalItemProperty ID

Why did my invoice fail UBL-CR-608?

The official rule states: "A UBL invoice should not include the InvoiceLine Item AdditionalItemProperty ID". The ID element under InvoiceLine/Item (Item/AdditionalItemProperty) exists in the generic UBL 2.1 schema but is not mapped to any EN 16931 business term, so a core-compliant invoice must leave it out. Receivers validating against EN 16931 will flag it because data in unmapped elements cannot be reliably processed. EN 16931 models item attributes (BG-32) as simple name/value pairs: only cbc:Name (BT-160) and cbc:Value (BT-161) are used inside cac:AdditionalItemProperty.

Official rule text

A UBL invoice should not include the InvoiceLine Item AdditionalItemProperty ID

Common causes

Exporting a full product-attribute record (codes, quantities, qualifiers, ranges) instead of a plain name/value pair
A PIM or catalogue integration serialising all attribute metadata into the invoice
A generic UBL library emitting every optional field of cac:AdditionalItemProperty

How do I fix it?

<cac:AdditionalItemProperty>
  <cbc:Name>Colour</cbc:Name>
  <cbc:Value>Black</cbc:Value>
</cac:AdditionalItemProperty>
