Currency Calc in BEx

Hi All.,

I have all the Cost of Sales is in USD in the Infocube.

I want to report on local currency depending on the country in the BEx.

Can I do this in the BEx with currency Keys or Do I have to use any thing else?

is this possible?

I hav all the exchange rates in BW.

Any ideas will be appriciated.

Thank you,

Sindu
