What does BR-64 mean? The Item standard identifier (BT-157) shall have a Scheme identifier.

Why did my invoice fail BR-64?

The Item standard identifier (BT-157) — a globally standardized product identifier for a line item, such as a GTIN — must have a Scheme identifier declaring which registry the identifier comes from. The scheme (an ISO/IEC 6523 ICD value) is required so the identifier can be interpreted unambiguously.

Official rule text

The Item standard identifier (BT-157) shall have a Scheme identifier.

Common causes

• cac:Item/cac:StandardItemIdentification/cbc:ID has a value but no schemeID attribute.
• The schemeID is not a valid ISO 6523 ICD code (e.g. 0160 for GTIN).
• A seller's own article number was placed in StandardItemIdentification instead of SellersItemIdentification, so no scheme applies.

How do I fix it?

<cac:StandardItemIdentification><cbc:ID schemeID="0160">04012345678901</cbc:ID></cac:StandardItemIdentification>.
