Hi Experts,

I have a hierarchy report created through report painter shown here:

Clik here to view.

The challenge here is to segregate data contained under 'Activity type' column into 3 different columns because our users are doing excel work every time after exporting this data to excel.

Could you please guide me if it is possible?

Please provide any pointers whatever you can give.

Thanks & Regards

Saurabh
