The currency is based on the Windows Regional settings
I want o calculate my price list complete new and sometimes the curancy is in USD or Euro. And i want to create my own mathematics here. I changed the currency in the windoes settings but it does nt changed currancy in act.
I've not tried it, but I think the currency is taken from the Regional settings when the database is created. It can't be changed later
Try changing the currency and then creating a new database.
Unfortunately, the Sales ops system doesn't support currency changes. I don't know if there is a way around this, but you might contact an ACT! Certified Consultant in ouside of North America and ask them if there's a solution as they would have to deal with this more than the posters here.
It would be possible to create a seperate system using the ACT! SDK to achieve what you're looking for... maybe one of the Euro ACCs has looked at this?
Let us know what you find out if you speak to one of them
