What it means
Every invoice line (BG-25) must contain the invoiced quantity (BT-129). It is how many units of the item the line charges for.
Why it matters
The buyer's software books and checks every line on its own, often against the purchase order. A line without this detail cannot be matched or posted, so the whole invoice is rejected.
How to fix it
Enter a quantity on every line, for example 1 for a single service or the number of hours or items. If you build the XML yourself, add cbc:InvoicedQuantity or cbc:CreditedQuantity (UBL) or ram:BilledQuantity (CII).
The rule as published
Each Invoice line (BG-25) shall have an Invoiced quantity (BT-129). Business terms: BG-25, BT-129
