What does BR-DEC-01 mean? The allowed maximum number of decimals for the Document level allowance amount (BT-92) is 2.
Why did my invoice fail BR-DEC-01?
The Document level allowance amount (BT-92), which is the value of a discount applied to the whole invoice rather than a single line, must be expressed with at most two decimal places. EN 16931 caps monetary amounts at 2 decimals so that totals reconcile exactly and rounding behaves predictably across systems.
Official rule text
The allowed maximum number of decimals for the Document level allowance amount (BT-92) is 2.
Common causes
- Passing through an unrounded computed discount such as 12.505 or 12.5001 from a percentage calculation
- Using full floating-point precision from an internal ERP field without rounding to currency scale
- Storing amounts in a base unit with 4 decimals and emitting them directly
How do I fix it?
Round to 2 decimals before serializing: <cbc:Amount currencyID="EUR">12.51</cbc:Amount> inside the document-level cac:AllowanceCharge with cbc:ChargeIndicator=false.
