Key Figure "revenue" showing Negative

Hi ,

I am preparing BW P&L report. I have "revenue" and "Expenses" in rows. I am getting "revenue" as Negative and "expenses" as positive. Is that how FI reporting works?

As a figure Revenue Value is correct but it is negative. I need to do further calculation on the basis of it --Please suggest me if anybody has ideas on FI P&L report in BW.

Thanks,

-Su
