What does BR-DEC-17 mean? The allowed maximum number of decimals for the Rounding amount (BT-114) is 2.
Why did my invoice fail BR-DEC-17?
The Rounding amount (BT-114), the small adjustment that rounds the payable amount up or down (e.g. to the nearest 0.05 or whole unit), must itself be expressed with at most two decimals. Holding it to 2 decimals keeps the amount-due calculation (tax-inclusive total minus paid plus rounding) consistent at currency scale.
Official rule text
The allowed maximum number of decimals for the Rounding amount (BT-114) is 2.
Common causes
- Computing the rounding delta at full floating-point precision
- Deriving it from a difference of two unrounded totals
- Emitting more than 2 decimals for cash-rounding adjustments
How do I fix it?
Round the adjustment: <cbc:PayableRoundingAmount currencyID="EUR">0.02</cbc:PayableRoundingAmount> in cac:LegalMonetaryTotal.
