Sum in ALV for rtwo different fields acc to currency wise

hi,

I have an internal table in which following are the fields

Currency

Amount(in different currency)

Amount1(in USD only)

Now i have to take total sum according to currency wise like for AUD,INR those are visible in mine currency field through ALV.

I am getting the total sum but for Amount(in USD only) gives sum according to currency wise. But it is in USD only so sum for USD has to be shown.

Now to do that so that i get the sum .
