Hi Mayank,
Thanks for the reply
I am using oops method.
I tried making the field which is to be made editable  as wa_fieldcatalog-edit = 'X'. But its not working. I didnt get you when you said  edit in layout object.
I also went through the demo programs but these programs are not having editable fields.
My code is as follows:
IF tree4 IS INITIAL.
* create container for alv-tree
  l_tree_container_name = 'TREE4'.
  CREATE OBJECT l_custom_container
    EXPORTING
      container_name              = l_tree_container_name
    EXCEPTIONS
      cntl_error                  = 1
      cntl_system_error           = 2
      create_error                = 3
      lifetime_error              = 4
      lifetime_dynpro_dynpro_link = 5.
* create tree control
  CREATE OBJECT tree4
    EXPORTING
      i_parent                    = l_custom_container
      i_node_selection_mode       = cl_gui_column_tree=>node_sel_mode_multiple
      i_item_selection            = 'X'
      i_no_html_header            = 'X'
      i_no_toolbar                = 'X'
    EXCEPTIONS
      cntl_error                  = 1
      cntl_system_error           = 2
      create_error                = 3
      lifetime_error              = 4
      illegal_node_selection_mode = 5
      failed                      = 6
      illegal_column_name         = 7.
* create hierarchy
  CALL METHOD tree4->set_table_for_first_display
    EXPORTING
      is_layout       = s_layo
    CHANGING
      it_sort         = it_sort
      it_outtab       = it_final
      it_fieldcatalog = it_fieldcat.
ELSE.
  CALL METHOD tree4->refresh_table_display
    EXPORTING
      it_sort           = it_sort
    EXCEPTIONS
      program_error     = 1
      failed            = 2
      cntl_system_error = 3
      others            = 4
  IF sy-subrc <> 0.
   MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
              WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
endif.
