BR-43

Every invoice line charge (BG-28) must carry an amount (BT-141). An allowance or charge without an amount changes nothing, and then does not belong in the document.

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

Official rule text

Each Invoice line charge (BG-28) shall have an Invoice line charge amount (BT-141).

Why does BR-43 happen?

Line charges are rare and often only half-built in the mapping: the group exists, and the amount is bound to a field the source system does not have.

How do you fix BR-43?

Write the amount into cbc:Amount inside cac:AllowanceCharge in UBL, ram:ActualAmount inside ram:SpecifiedTradeAllowanceCharge in CII. On how amount, base amount and percentage relate, see PEPPOL-EN16931-R040.

In the XML

A UBL fragment. The CII path is named above — same change, different element names.
