What does BR-DEC-24 mean? The allowed maximum number of decimals for the Invoice line allowance amount (BT-136) is 2.

An Invoice line allowance amount (BT-136), a discount applied within a single invoice line, may carry at most two decimal places. This keeps line-level discounts at currency precision so they subtract cleanly from the line net amount.
Official rule text
The allowed maximum number of decimals for the Invoice line allowance amount (BT-136) is 2.
Common causes
- Calculating a percentage discount as a float without rounding (e.g. 5.005)
- Prorating a total discount across lines and emitting the raw quotient
- Passing through more decimals than the currency minor unit allows
How do I fix it?
Round to 2 decimals: <cac:AllowanceCharge><cbc:ChargeIndicator>false</cbc:ChargeIndicator><cbc:Amount currencyID="EUR">5.00</cbc:Amount></cac:AllowanceCharge>
