BR-CO-11

The sum of allowances at document level (BT-107) must equal the sum of the individual allowance amounts (BT-92) exactly.

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

Official rule text

Sum of allowances on document level (BT-107) = Σ Document level allowance amount (BT-92).

Why does BR-CO-11 happen?

The total is taken from your own invoice object while the individual allowances are written through a filter — an allowance of zero skipped, say, or a discount also folded into the line.

How do you fix BR-CO-11?

Build BT-107 from exactly the allowances the document contains: cbc:AllowanceTotalAmount inside cac:LegalMonetaryTotal as the sum of every cac:AllowanceCharge whose cbc:ChargeIndicator is false in UBL, ram:AllowanceTotalAmount in CII.
