Currency Conversion

Hi Team,

How do I create Corrency Conversion in Query Designer.

I am using 0Currency and the data is currently in USD.

If the user changes the currency from USD to EUR, the netprice must change from USD to EUR.

Do I need to create a formula for each country with currency difference, or is there a easy way to add this feature as a filter condition so that the users can change it.

Please help.

Thanks

Anita
