Calculated Column - Currency Conversion Fields Inactive

Hi,

I am new at Hana Studio Views Modeling, and I find a strange situation.

I am defining a Calculation View, and I need to perform a Currency Conversion In the last Projection of the View.

When I try to add a Calculated Column to store the converted amount I was not able to introduce the target currency, the exchange type and the conversion date because the input fields were inactive. (You can see a print screen in the attached file)

Can you help me solving this issue? Or suggest another way to perform the currency conversion?

Thanks and best regards,

Raquel
