BR-36: Each document-level charge needs an amount (BT-99)

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-99

Applies only to document-level cac:AllowanceCharge elements with cbc:ChargeIndicator = true (a charge); the validator checks that each contains cbc:Amount. The test text published with the rule is malformed (it looks for lower-case cbc:amount via an absolute path), but the condition actually executed is the presence of cbc:Amount, matching the official message.

How to fix it

Add the charge amount inside each document-level charge, e.g. <cbc:Amount currencyID="SAR">10.00</cbc:Amount>.
