How to use the same Tax Registration Number for a Customer and a Supplier

Hi,

We have a supplier that is at the same time a customer and we want to create a supplier in AR and a customer in AR and assign the same tax registration number.

I have read that we can do that if we create first the supplier adding the TRN and then go to AR/Customers, and search entering the TRN entered for the supplier.

If this is possible, is the result that we are creating a single party that is at the same time Customer/Supplier?

Can you advice?

Thanks,

V
