BR-KSA-13: 'Not subject to VAT' (O) charges must have a VAT rate of 0 if given

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

Warning: accepted with a warningConditional, see belowFields: BG-21, BT-102, BT-103

Applies to each document-level cac:AllowanceCharge with cbc:ChargeIndicator = true whose cac:TaxCategory/cbc:ID is 'O': if cbc:Percent (BT-103) is present it must be 0. The executed check fails only on a non-zero Percent, while the listed test text implies Percent must be absent.

How to fix it

In the charge's 'O' cac:TaxCategory either omit cbc:Percent or set <cbc:Percent>0</cbc:Percent>.
