BR-KSA-93: Zero-rated (Z) line VAT breakdown needs an exemption reason code

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-25, KSA-33, KSA-41

Each line-level cac:TaxTotal/cac:TaxSubtotal/cac:TaxCategory with cbc:ID 'Z' (VAT) must have a non-empty cbc:TaxExemptionReasonCode (KSA-41). The executed check tests presence only (allowed values are checked by BR-KSA-CL-07), and it is evaluated only when the document also contains a standard-rated (S) VAT category.

How to fix it

Add a reason code to that line TaxCategory, e.g. <cbc:TaxExemptionReasonCode>VATEX-SA-32</cbc:TaxExemptionReasonCode>.
