How to hide the first 2 levels of Hierarchey in bex

Hi Guys,

I am using Sales Office Hierarchy in report. Hierarchy name is 'First Sales Hierarchy' which is coming as a root node.My requirement is that I do not want to see the first 2 levels of hierarchy,but I want to see the all 3rd level hierarchies only.I have tried with Display of hierarchy properties in the Query its not working.Is there way to go creating customer exit variable to achieve this?

Emple: Screen shot

I have to show only the 3rd level Hierarchy nodes only like corporate departments if user selects Corporate at selection etc..

How can achieve this.can you please guide ...

Thanks in advance
