Rule family: KSA - business rules (BR-KSA).
Standard: BR-KSA (ZATCA). Severity: WARNING.
Why your invoice is flagged
ZATCA runs the official EN 16931 + BR-KSA business rules before clearance/reporting. This rule is a warning — the invoice may still be accepted, but resolve it before you submit.
Wie man es behebt
Correct the invoice element referenced in the rule (the BT-/BG- term above) in your ERP mapping so it satisfies the constraint, then re-validate. The fault is usually in how your software generates the field, not in the rule itself.
Vor dem Senden prüfen
Upload your ZATCA UBL invoice to the validator to confirm this rule — and every other EN 16931 / BR-KSA rule — passes. Validation runs the official ZATCA SDK schematron.
