BR-CO-15: The invoice total with VAT (BT-112) does not equal the total without VAT…
What it means
The invoice total with VAT (BT-112) does not equal the total without VAT (BT-109) plus the total VAT amount (BT-110).
How to fix it
Recompute BT-112 as BT-109 + BT-110 at the source and re-issue. Arithmetic mismatch -- reported, never auto-repaired.
