Result row is not showing expected result

Question

Dear All ,
I have below  requirement to generate mix variance 
  PY Mix
PY Mix Diff
  PY Mix
  Val Gr -
0.00
0.00
1,015.6823529
1,015.68
0.00
0.00
52,486.5048653

2,836.12
0.00
0.00
45,582.8437071
45,582.84
Result
0.00
3,09,668.66
-2,07,747.5092285
1,01,921.15
Result in Bex
Expected Result
PY Mix L- Used No definition in   Result
Val Gr -    Used Sum in result
PY Mix Diff  = Val Gr - PY Mix
But above formula is not working for Result row ??
expected 3,09,668.66 but showing 0.00
Any ideas to crack this .
All your valuable inputs are highly  appreciated .

Answer 1

Dear Suman 
Thank you so much for your reply .
PY Mix and Val Gr KFs both key figures  has got same definition(Same formula ).So i cant use Summation for both KYF in Exp Agge
For Val Gr   -Result Row should be sum of values in Column , i have maintained no settings .And showing value as expected
Val Gr -(CKF)
1,015.68
52,486.50
2,836.12
45,582.84
1,01,921.15 -Result (Sum along columns)
For PY Mix  - Result Row should be as per formula defined , i have maintained summation in Exp aggregation  .And showing value as expected
PY Mix -(CKF)
1,015.68
52,486.50
2,836.12
45,582.84
-2,07,747.50-Result (According to formula used )
But When i use these to kyf in another formula Result row are not calculating as per Expectation
PY MIX DIFF  = Val Gr - PY Mix
                          3,09,668.66 (expected )
                        = 0 (but final result )
any other inputs to make it
