Official rule text
The allowed maximum number of decimals for the Invoice line allowance base amount (BT-137) is 2.
Common causes
- Deriving the base from an unrounded intermediate calculation
- Currency conversion of the base amount producing 3+ decimals
- Emitting full float precision instead of quantizing to 2 places
How do I fix it?
Round the base amount: <cac:AllowanceCharge><cbc:ChargeIndicator>false</cbc:ChargeIndicator><cbc:BaseAmount currencyID="EUR">100.00</cbc:BaseAmount></cac:AllowanceCharge>
