Hi veerapaneni,
According to your description, you want to calculated the increment percentage and difference between two fiscal year week within each week. Right?
In this scenario, since we need to do calculation based on values between dynamically generated cells, we can't simply use expression to achieve this goal. In this scenario, we need to use custom code to record the value for fiscal 14 and fiscal 15, then
we can calculate the difference and percentage within the column group. We have tested your case in our local environment, please refer to the steps and screenshots below:
1. Add the custom code below into the report (you may need to modify the data type based on your scenario:
Public Shared Value1 as Integer
Public Shared Value2 as Integer
Public Shared previous as string
Public Shared previousweek as string
  Public Shared Function GetValue(Value as Integer,product as String,Week as String) as Integer
If product =previous and Week =previousweek  Then
     Value2=Value
Else
previous=product
previousweek=Week
Value1=Value
End If
     return Value
  End Function
  Public Shared Function GetPct()
     return (Value2-Value1)/Value1
  End Function
Public Shared Function GetDiff()
     return Value2-Value1
  End Function
2. Design the matrix like below:
3. The result look like below:
