BR-KSA-08: Seller ID needs a valid scheme (CRN, MOM, MLS, SAG, OTH, 700)

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

Warning: accepted with a warningAll invoicesFields: BT-29, BT-29-1

cac:AccountingSupplierParty/cac:Party/cac:PartyIdentification/cbc:ID (BT-29) must exist with a @schemeID (BT-29-1) of CRN, MOM, MLS, SAG, OTH or 700. The executed check only verifies the ID exists and the scheme; it does not check the 'alphanumeric only' or 'only once' parts of the official text.

How to fix it

Add the seller identifier with its scheme, e.g. <cac:PartyIdentification><cbc:ID schemeID="CRN">1010010000</cbc:ID></cac:PartyIdentification>, using letters and digits only and the first applicable scheme in the order CRN, MOM, MLS, SAG, OTH, 700 per the official text.
