I want to add an expression to each row in the ratio column. I want to divide row total by group total and show that amount in the ratio column for each row. For the first row of ratio column it should be 11/44.
My design tab has the following design.
Take the formula in your total row (something like Sum(Fields!Survey1.Value)
) and add the group name over which you want to sum your total, giving something like Sum(Fields!Survey1.Value,"ExamGroup")
. That should allow you to access the total at each row of the group, so you can get the ratio of each row with something like this:
Fields!Survey1.Value / Sum(Fields!Survey1.Value,"ExamGroup")
