Here is a issue to me , i gone through several blogs and posts but i did not get it, there is Custom Aggregate function using for different columns and etc... to perform aggregate functions and all , but i did not see performing "Subtraction" Math function . and i did not see performing this function on different Group footer totals (Only on GroupFooter Values ) .
I have an Example in attachment i have Grouped with a column "Group_No" (of course Visibility of that column is false) Now i need to perform
Subtraction for that Group Footer total values Only on footer Values I need to Work.
