number series differently for posted sales invoice

Hi, One my customer is asking the Posted sales invoice number series differently.

. That means they are mainting 3 different Number series for sales invoices. 1. Domestic

  1. Export

  2. Third party sales So is it possible to assign the number series differently for posted sales invoice

You are still asking if it is possible - you are not asking how you would develop a solution to have a different number series depending upon teh customer group.

This is also teh technical forum not the developers forum.

It is possible - as standard you can define relationships btw different Number Series. And if displaying field “Posting No. Series” on sales-form (Order, Invoice, CRM, user is able to change. Take a look at the online-help in NAV.
