India GST Third Pary Registrations

we will be using tax rules and reporting codes to drive the correct GST.

How can I add a Third Party Registration, Reporting Code to a customer site if I do not have a Primary Registration Number for the customer?

Third Party Registrations> Registrations Tab

    Primary Registration Number is a mandatory field

Third Party> Reporting Codes Tab

     Reporting Type LOV is empty unless I add a Registration in the Registrations Tab

    

thanks
