## Official rule text

Each Invoice line (BG-25) shall have an Invoiced quantity (BT-129).

## Why did my invoice fail BR-22?

Each Invoice line (BG-25) must have an Invoiced quantity (BT-129), the number of units being billed on that line. The quantity, combined with the Item net price (BT-146), is what produces the line net amount, so it is mandatory even when it is 1 (or negative for a corrective line). This rule ensures every line quantifies what is being charged.

## Common causes

- The cac:InvoiceLine has no cbc:InvoicedQuantity element (or cbc:CreditedQuantity on a credit note line).
- The quantity was assumed to be 1 and left out of the XML.
- The value was written as text/empty rather than a valid decimal number.

## How do I fix it?

```
<cbc:InvoicedQuantity unitCode="C62">2</cbc:InvoicedQuantity>
```
