BR-04

The invoice must carry an invoice type code (BT-3) — the code saying whether this is an invoice, a credit note or a partial invoice.

Severity: Error
Applies to: CII, UBL
Rule set: v2026-01-31

Official rule text

An Invoice shall have an Invoice type code (BT-3).

Why does BR-04 happen?

The document type is often a house abbreviation in the source system with no mapping to a standard code. Where the mapping is missing, nothing gets written in preference to something wrong.

How do you fix BR-04?

Set BT-3 to a UNTDID 1001 code — 380 for a commercial invoice, 381 for a credit note, 384 for a correction: cbc:InvoiceTypeCode in UBL, ram:TypeCode in CII. On which codes are permitted, see BR-DE-17.
