I have to create this report that displays as follows


Product_ID Sale_Value Cumulative %_of_Totalsales Rating
---------- ---------- ---------- --------------- ------
   1 100 100
   2 250 350
            --------- --------
      ToTal: 350

So I want to know how to calculate the Cumulative inside Cristal reports in order to get the % --> PercentageOfSum(,)

All this time I was doing this in C# and inserting the results to the data set but this is very inefficient

Please Help --- IT Is Very Urgent
