RMS module installation with Sales tax or simple Value Added Tax option ?

Hi All,

There is an impact for these two situations?

Which one will be preferred to be used: sales tax option or VAT option?

We are using RMS module Version 14.0.0.0

This module was installed with sales tax option.

How can we create and match invoices for supplier which has sales tax applied on his merchandise?

How can we add sales tax to the supplier for this case?

Thank you for your answers,

Adriana
