Hi ,
Here is the example from sap help .. the code runs.
  data: gt_outtab1 type table of sflight,
        gt_outtab2 type table of sflight.
  data: ls_outtab type sflight.
  data: gr_tree  type ref to cl_salv_tree.
  data: nodes type ref to cl_salv_nodes,
        node type ref to cl_salv_node,
        key type SALV_DE_NODE_KEY.
*... Select Data
  select * from sflight into corresponding fields of table gt_outtab1 up to 5 rows.
*... Create Instance with an Empty Table
  call method cl_salv_tree=>factory
    IMPORTING
      R_SALV_TREE = gr_tree
    changing
      t_table      = gt_outtab2.
*... Add the Nodes to the Tree
  nodes = gr_tree->get_nodes( ).
  loop at gt_outtab1 into ls_outtab.
    try.
      node = nodes->add_node( related_node = key
                              relationship = cl_gui_column_tree=>relat_first_child ).
      node->set_data_row( ls_outtab ).
    catch cx_salv_msg.
    endtry.
  endloop.
*... Display Table
  gr_tree->display( ).
