Official rule text

Sum of charges on document level (BT-108) = Σ Document level charge amount (BT-99).

Why does BR-CO-12 happen?

Freight and packaging are often totalled in the header and carried as a line of their own at the same time. The amount then appears twice in the document and only once in the total.

How do you fix BR-CO-12?

Sum BT-108 from every cac:AllowanceCharge whose cbc:ChargeIndicator is true and write the result to cbc:ChargeTotalAmount in UBL, ram:ChargeTotalAmount in CII. A charge belongs either in the line or at document level, never in both.
