BR-KSA-36: Supply end date (KSA-24) must not be before supply date (KSA-5)

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: KSA-24, KSA-5

Applies when cac:Delivery has both cbc:ActualDeliveryDate (KSA-5) and cbc:LatestDeliveryDate (KSA-24) as valid YYYY-MM-DD dates: the end date must be greater than or equal to the supply date. If either date is missing or not a valid YYYY-MM-DD date, this rule does not compare them.

How to fix it

Make cbc:LatestDeliveryDate the same day as or later than cbc:ActualDeliveryDate, both in YYYY-MM-DD format.
