What does UBL-CR-594 mean? A UBL invoice should not include the InvoiceLine Item CommodityClassification CommodityCode

Why did my invoice fail UBL-CR-594?

The official rule states: "A UBL invoice should not include the InvoiceLine Item CommodityClassification CommodityCode". The CommodityCode element under InvoiceLine/Item (Item/CommodityClassification) 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 supports item classification (BT-158) only via cac:CommodityClassification/cbc:ItemClassificationCode with listID/listVersionID attributes.

A UBL invoice should not include the InvoiceLine Item CommodityClassification CommodityCode

Common causes

Using cbc:CommodityCode, cbc:NatureCode or cbc:CargoTypeCode instead of cbc:ItemClassificationCode
Mapping customs or logistics classification data into the invoice
A generic UBL library emitting every optional classification field

How do I fix it?

  <cbc:ItemClassificationCode listID="SRV">09348023</cbc:ItemClassificationCode>
