## Why it fails

- The VAT total changed (another rate, a rounding fix) but `cbc:TaxInclusiveAmount` was not recalculated.
- The invoice has a second `cac:TaxTotal` in another currency, and the wrong one was added up; the rule uses the tax total in the document currency.
- The amount with VAT includes the paid amount or the rounding amount, which belong in BT-113 and BT-114 instead.

## How to fix it

- Set BT-112 (`cbc:TaxInclusiveAmount`, `ram:GrandTotalAmount` in CII) to BT-109 plus BT-110, rounded to two decimals. Adjust the amount due for payment (BT-115) afterwards, since BR-CO-16 checks it against BT-112.
