Inverse Formula - Disaggregation

Hi Experts ,

I have a input ready % share formula in my query again calquarter and Calmonth .

% share = Share Value *100

inverse formula = % Share /100

Let say if I enter 25 in %share then .25 get stored against Share value in cube for Calquarter "3/2015" but that 25 gets divided among respective months (07/2015,08/2015,09/2015) of quarter as 10 , 10, 5

What my requirement is that if I enter % share as 25 for a Quarter then the same value 25 should get stored for respective months as 25, 25,25

I have set Dis-aggregation and analog distribution again self reference .

Request your help!!!

Thanks
