When i use the first option, i get like this type of view; 'HOLDING' the highest level every time repeat the second level, i don't want that actually. This is a graph, not a pivot view. Thank you for the help.

I guess "link type drilldowns" means create another report and use action link to connect each other, right?

Okey, i get it. So, is there a way showing just a level name in graph? ( example: when i drill a sector name , i want to written just compaines, not sector and company)
