BR-KSA-33: Every invoice needs an invoice counter value (ICV, KSA-16)

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: KSA-16

The invoice must contain a cac:AdditionalDocumentReference with cbc:ID = 'ICV', and a non-empty cbc:UUID under cac:AdditionalDocumentReference, which holds the invoice counter value (KSA-16).

How to fix it

Add <cac:AdditionalDocumentReference><cbc:ID>ICV</cbc:ID><cbc:UUID>10</cbc:UUID></cac:AdditionalDocumentReference>, with your counter value in cbc:UUID.
