BR-22: Each invoice line needs an invoiced quantity (BT-129)

Explained by Matheel from ZATCA's rule text and the condition SDK 3.4.8 executes · Updated October 24, 2026

Error: the invoice is rejectedAll invoicesFields: BG-25, BT-129

Checks each cac:InvoiceLine / cac:CreditNoteLine for cbc:InvoicedQuantity. The check the validator actually executes is stricter than the displayed test: it fails when cbc:InvoicedQuantity is missing or its text is exactly '0', and it does not accept cbc:CreditedQuantity as a substitute (the displayed test accepts either element).

How to fix it

Add <cbc:InvoicedQuantity>1.00</cbc:InvoicedQuantity> to every line, and do not write the quantity as the bare value 0.
