## Official rule text

Each Invoice line (BG-25) shall have an Invoice line net amount (BT-131).

## Why did my invoice fail BR-24?

Each Invoice line (BG-25) must have an Invoice line net amount (BT-131): the total net (VAT-exclusive) value of the line after line-level allowances and charges. It is the amount that feeds the Sum of Invoice line net amounts (BT-106) and must reconcile with quantity times net price. This rule ensures every line contributes a concrete monetary value.

## Common causes

- The cac:InvoiceLine is missing its cbc:LineExtensionAmount element.
- LineExtensionAmount is present but lacks the currencyID attribute or is empty.
- The value does not equal (Invoiced quantity x Item net price / base quantity) net of line allowances/charges, so it is rejected downstream.

## How do I fix it?

```
<cbc:LineExtensionAmount currencyID="EUR">200.00</cbc:LineExtensionAmount>
```
