Hi,
Please note that we have to issue an invoice on own company on performed chargeable services. In this case seller and buyer will be the same party. So, when we test this case, we get the below error code in response.
Error-code : BR-CUSTOM-VALIDATION-01
Category : KSA
Detail : [BR-CUSTOM-VALIDATION-01]- The Seller VAT registration number or seller group VAT registration number (BT-31) of The invoice must not match the buyer VAT registration number (BT-48).
Please check and advise on this case.
