Each Document level allowance (BG-20) shall have a Document level allowance amount (BT-92).
Why ZATCA invoices fail rule BR-31 (ERROR) and how to fix it: Each Document level allowance (BG-20) shall have a Document level allowance amount (BT-92).
Was diese Regel prüft
Each Document level allowance (BG-20) shall have a Document level allowance amount (BT-92).
Rule family: Business rules - integrity constraints (BR).
Standard: EN 16931 (UBL, KSA-tuned). Severity: ERROR.
Warum Ihre Rechnung abgelehnt wird
ZATCA runs the official EN 16931 + BR-KSA business rules before clearance/reporting. This rule is an error — the invoice is rejected until you fix it.
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.
