ALV Tree editable

[Former Member]

Hi all,

Is it possible to use any Tree Control and make some fields editable?

I was trying with CL_GUI_ALV_TREE, but when i set the field 'editable' of lvc_s_layi to 'X' an ABAP-Shortdump occurs.

Some help?

Thanks.

Hi,

Check this code :

  create object g_alv_tree
    exporting
        parent              = g_custom_container
        node_selection_mode = cl_gui_column_tree=>node_sel_mode_multiple
        item_selection      = 'X'
        no_html_header      = 'X'
        no_toolbar          = ''
    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.
  if sy-subrc <> 0.

  endif.

   perform build_fieldcatalog.

  call method g_alv_tree->set_table_for_first_display
     exporting
               is_hierarchy_header  = l_hierarchy_header
     changing
               it_fieldcatalog      = gt_fieldcatalog
               it_outtab            = gt_sflight. 


form build_fieldcatalog.
  data: ls_fieldcatalog type lvc_s_fcat.

  call function 'LVC_FIELDCATALOG_MERGE'
       exporting
            i_structure_name = 'SFLIGHT'
       changing
            ct_fieldcat      = gt_fieldcatalog.

  loop at gt_fieldcatalog into ls_fieldcatalog.
    case ls_fieldcatalog-fieldname.
      when 'CARRID' or 'FLDATE'.
        ls_fieldcatalog-edit = 'X'.  "<< need to edit the field
    endcase.
    modify gt_fieldcatalog from ls_fieldcatalog.
  endloop.

endform.                               " build_fieldcatalog
