Show Org Unit Tree Structure in Search Help

Hello Experts,

I have a requirement to show Org Unit Tree structure for a F4 Search help in a Z Component.

I tried searching some threads but can find only to show Flat structure in Search help.

Also tried using MDOMS_ORGDATA-ORGSearchWindow,  but dont have any clue to find a Tree structure.

So help with the process of Creating a Tree View for Org Unit and showing it in a F4 help.

Thanks in Advance.
