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

- Context: `//ram:IncludedSupplyChainTradeLineItem`
- Test: `(ram:SpecifiedLineTradeDelivery/ram:BilledQuantity)`

## Why it fails

- A line has no `cbc:InvoicedQuantity` (`cbc:CreditedQuantity` in a credit note, `ram:BilledQuantity` in CII), common for lump-sum services.

## How to fix it

- Give every line a quantity. For a lump sum, use `1` with the unit code `C62` (one) or `LS` (lump sum).
