## Official rule text

Sum of allowances on document level (BT-107) = Σ Document level allowance amount (BT-92).

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

The document-level total of allowances (BT-107) must equal the sum of all individual document-level allowance amounts (BT-92). This keeps the header "sum of allowances" consistent with the actual document-level allowance entries so downstream totals reconcile.

## Common causes

- A document-level allowance not included in the AllowanceTotalAmount.
- Line-level allowances mistakenly added into the document-level allowance total.
- Rounding of individual allowances not matching the summed total.
- AllowanceTotalAmount left as 0 or absent while allowances exist.

## How do I fix it?

```
Sum all document-level allowances into the header: two allowances of 10.00 and 5.00 give <cac:LegalMonetaryTotal><cbc:AllowanceTotalAmount currencyID="EUR">15.00</cbc:AllowanceTotalAmount>...</cac:LegalMonetaryTotal>
```
