Can I get a new CKF from the calculated results of the other two KFs?
I uses some boolean operators to calculate two key figures, say KF1 and KF2. What I want to do next is to calculate KF3 = sum(KF1)/sum(KF2) . The trouble is: sumct function will get a different result from the real summation of KF1 or KF2. I can only get it by means of the calculated result. However this kind of result is just for display, isn't it?
Then, I can't find anyway to calculate KF3!
