What does UBL-CR-582 mean? A UBL invoice should not include the InvoiceLine Item StandardItemIdentification ExtendedID

Why did my invoice fail UBL-CR-582?

The official rule states: "A UBL invoice should not include the InvoiceLine Item StandardItemIdentification ExtendedID". The ExtendedID element under InvoiceLine/Item (Item/StandardItemIdentification) 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 uses only the identifier with its scheme: cac:StandardItemIdentification/cbc:ID with a schemeID attribute (BT-157).

Official rule text

A UBL invoice should not include the InvoiceLine Item StandardItemIdentification ExtendedID

Common causes

A UBL generator emitting all optional children of cac:StandardItemIdentification instead of only cbc:ID
Putting barcode or physical-attribute data here instead of encoding the scheme in the schemeID attribute of cbc:ID
Copying a catalogue UBL structure into the invoice

How do I fix it?

<cac:StandardItemIdentification>
  <cbc:ID schemeID="0160">05704066204093</cbc:ID>
</cac:StandardItemIdentification>
