Hi Abhilash,
Lets just assume, the total at the end is not in the requirement. The only this is how to dynamically put the number of % columns after each type ( salary & stipend) after all the years are rendered. So what we are looking for here is just add the 'x-1" number % change columns based on the "x" number of years thee user has selected.
Now , based on your comments "Insert multiple columns using the 'Calculated Member' option with Dynamic Insertion formula for 'Totals' and Percentages - Percentages that display between the columns and Percentages that display under Grand Totals"
Do you mean that I create the max ( say 5 or 10) columns, and then if user selects 3 years, crystal will render only 3 columns?
