how to calculate % in PPS 2010

Question

i have these columns in the table and made this table as the FACT table and also using time intelligence filter in the PPS2010.. i have measures , sum (materials), sum (sales) and sum (material_%)

in the PPS dashboard design i have included this cube and all the measures.. and using an analytic chart.. i have developed separate graphs for each columns (material, sales, material_%)..

for the sales and materials there is no problem , when i use the time filter in the material_% graph i used the time filter current quarter in months (showing three months ) shows the correct value..

when i use the current quarter filter (sum of all the 3 months)

its showing 146% (83 +33 +30) --> for actual values

and 150 % ( 50+50+50) --> for target values

actually it showed show me 46% for actual and 50% for target ,

it should be sum of material in all the 3 months / sum of sales in all the 3 months but its just calculating sum of material_% column of all the 3 months

time filter : year :: Halfyear ::quarter:: Month::Day

DataBase Table:

 Month             Year       Material   sales   Material_%  [ material / sales]
 Jan_Act          2011        500         600       83
 Jan_target       2011        400         800       50
