BR-CO-16: The amount due for payment (BT-115) does not equal the total with VAT (BT-112)…
What it means
The amount due for payment (BT-115) does not equal the total with VAT (BT-112) minus paid amount (BT-113) plus rounding (BT-114).
How to fix it
Recompute BT-115 from BT-112, BT-113 and BT-114 at the source and re-issue. Arithmetic mismatch -- reported, never auto-repaired.
