Hi,

When creating a contract, in foreign currency, we get the following error: "Enter the currency conversion rules on the Currency Conversion tab"

As checked, rates are in order, they are defined ok for those specific dates.

So, not sure what the error mean. Did not find it on the support portal...

Can you please check?

Thank you,

Elena
