BR-KSA-53: Each line needs a line amount with VAT (KSA-12) on standard invoices

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

Error: the invoice is rejectedStandard tax invoices (B2B)Fields: KSA-12, KSA-2

For standard tax invoices and their notes (InvoiceTypeCode @name starting '01'), every cac:InvoiceLine must contain a non-empty cac:TaxTotal/cbc:RoundingAmount (KSA-12).

How to fix it

Add <cbc:RoundingAmount currencyID="…">…</cbc:RoundingAmount> inside each line's cac:TaxTotal, after cbc:TaxAmount.
