I want to achieve a drill down report where based on the drill level a certain column should show, otherwise be hidden dynamically (without republishing).
These screens should help.
1. Design View https://i.stack.imgur.com/sd2SU.jpg
2. Preview - What I want (before Drill down) https://i.stack.imgur.com/0bjqI.jpg
3. Preview - What I want (after Drill Down) https://i.stack.imgur.com/GMcoa.jpg
4. Preview - What I want (after Drill up) https://i.stack.imgur.com/NowpF.jpg
The screens are just a dummy I made up.
