Implement a class which should do the following things:

create a CL_GUI_DIALOGBOX_CONTAINER

create a CL_GUI_ALV_TREE (or some other tree_control), referring to the dialogbox_container

modify the fieldcatalog for using hotspots / layouts etc

implement event-handler for hotspot, node_click, etc.

declare a public data-structure for the selected data.

...

any functionality for classes and the events of cl_gui_alv_tree is possible, also drag 'n drop and so on.

...

You have to define something like this in your report:

AT SELECTION-SCREEN
  ON VALUE-REQUEST FOR +your_fieldname+.
  SUPPRESS DIALOG.

...

Insert code to create an instance / call a method in your class

...

At F4 or click on the select-icon, the dialogboxcontainer will appear and shows your tree-control. The user is been able to select one (or some, depending on the value for sel_mode in the layout-structure).

Normally I use this construct for an alv_grid to implement user-define f4-helpscreens, it works very good.
