## Official rule text

The allowed maximum number of decimals for the Sum of charges on document level (BT-108) is 2.

## Why did my invoice fail BR-DEC-11?

The Sum of charges on document level (BT-108), the total of all document-level charges, must have at most two decimals. The 2-decimal cap lets it add cleanly to the line-net sum when computing the tax-exclusive total.

## Common causes

- Aggregating charges that were not individually rounded
- Percentage-based charges summed at full precision
- Floating-point residue in the accumulator

## How do I fix it?

```
Round the total: <cbc:ChargeTotalAmount currencyID="EUR">75.00</cbc:ChargeTotalAmount> in cac:LegalMonetaryTotal.
```
