House Number - HOUSE_NUM1 in Customer Master

According to the below statements, only the below address fields are mandatory for tax invoices however on the sandbox system we receive an error message when field Building/House Number - HOUSE_NUM1 in empty, so should this field be populated?

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).

Dear @Fatma,

Please don’t use the sandbox for testing your test data and invoices.
as it’s already preconfigured with static data.

please use Simulation environment to test your own invoices with real valid responses.

Regards,
