How to use KF calculations in WAD

Hi All,

We are migrating BW3.5 WAD reports to BI7, in 3.x we have table interface class which is coded for calculations based on the KeyFigures and this needs to implemented in BI7.

for E.g in WAD KF1,KF2,KF3 in the class we are getting the result of KF3 based on KF1 & KF2 values
KF3 = KF1/(KF2-KF1)*100

Any ideas how to implement these forumla's in WAD without changing the formula;s in Bex query as our user need both[Bex Reports & WAD]?

Regards,
