Material Description in the E-Invoice and XML file

XML and business rules

We are confused regarding the material description that it should be in Arabic language but my question is it should be in Arabic in the tax invoices only or the simplified tax invoices as well?

and the same regarding the customer’s name and address I believe these should be in AR as well but for the tax invoices only or the simplified as well?

All the data fields that are visible on human readable form of the invoice must be in Arabic. VAT Regulations require the Tax Invoices and Simplified Tax Invoices (along with corresponding credit notes or debit notes) to be in Arabic mandatorily. Invoice can be bilingual and include English as well. ​​
