## Official rule text

The allowed maximum number of decimals for the Paid amount (BT-113) is 2.

## Why did my invoice fail BR-DEC-16?

The Paid amount (BT-113), any amount already paid against the invoice, is limited to two decimals. Because it is deducted when computing the amount due, it is capped at currency precision so the remaining balance reconciles exactly.

## Common causes

- Prepayment amount stored with more than 2 decimals
- Partial-payment figure carried at internal precision
- Amount converted from another currency without re-rounding

## How do I fix it?

```
Round the paid amount: <cbc:PrepaidAmount currencyID="EUR">500.00</cbc:PrepaidAmount> in cac:LegalMonetaryTotal.
```
