I thought this was governed by the Country in Setup> Time & Place> Business Zones?
We are in the UK and though we aren't using the Parts & Billing for anything when I go into the rates section the currency unit is listed as Pounds Sterling.
Thank You for Your answer.
I created two new Business zones : Swiss french and Swiss german and referenced them in my Locations, but it didn't work.
Since I've modified the Country in the Default Settings it works fine.
Thanks for Your help.
