BR-CO-11: Allowance total must equal the sum of document-level allowances

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

Error: the invoice is rejectedAll invoicesFields: BT-107, BT-92

cac:LegalMonetaryTotal/cbc:AllowanceTotalAmount (BT-107) must equal the sum of cbc:Amount (BT-92) of the document-level cac:AllowanceCharge elements with cbc:ChargeIndicator = false, rounded to two decimals. It also passes when there is neither an AllowanceTotalAmount nor any document-level allowance.

How to fix it

Set cbc:AllowanceTotalAmount to the rounded sum of all document-level allowance amounts, or omit it when the invoice has no document-level allowances.

ZATCA's official text
