Is the customer building number mandatory for local customers? What are all mandatory fields that need to be included in the address?
As per the Electronic Invoice XML Implementation, role (BR-KSA-10) Buyer address must contain a street (BT-50), city (BT-52), postal code (BT-53), country code (BT55). This rule does not apply on the simplified tax invoices and associated credit notes and debit notes (KSA-2, position 1 and 2 =02).
