BR-CO-16 error
What this rule checks
Explanation
The Amount due for payment (BT-115) — the final figure the buyer actually needs to pay — must equal the total with VAT from BR-CO-15 (BT-112), minus any amount already paid in advance (BT-113), plus any rounding adjustment (BT-114).
How to fix it
Recompute BT-115 as BT-112 minus BT-113 plus BT-114. If no advance payment or rounding applies, Paid amount and Rounding amount should be 0 (or omitted, per the syntax's rules), so BT-115 equals BT-112.
