Hi Manuel,
I believe you are applying currency translation (on Local Currency KeyFigure) at BEx query level. In that case, you will be passing the Exchange Rate and To Currency as parameter to queries.
Let's assume, you want to verify local currency for a particular country. Then just pass '#' to Exchange Rate and To Currency. This will show your local currency value same as InfoCube value.
Hope this is what you are looking for? correct me if I'm wrong.
Thanks,
