ALV grid with editable fields

Question

Dear Colleagues,
I develop an ALV grid with OO standard methods. Before the first display of the table I define the editable fields. It works fine.
I have a problem : if the table is empty and I press the standard icons "Append a line" or "Insert a line", the new line don't have the defined editable characteristics.for fields. Is there a standard method which I have forgotten ?
Thanks a lot and kind regards
Peter

vs_toolbar_excluding = cl_gui_alv_grid=>mc_fc_loc_delete_row.
    APPEND vs_toolbar_excluding TO i_toolbar_excluding.
    vs_toolbar_excluding = cl_gui_alv_grid=>mc_fc_loc_append_row.
    APPEND vs_toolbar_excluding TO i_toolbar_excluding.
    vs_toolbar_excluding = cl_gui_alv_grid=>mc_fc_loc_copy_row.
    APPEND vs_toolbar_excluding TO i_toolbar_excluding.
    vs_toolbar_excluding = cl_gui_alv_grid=>mc_fc_loc_insert_row.
    APPEND vs_toolbar_excluding TO i_toolbar_excluding.
    vs_toolbar_excluding = cl_gui_alv_grid=>mc_fc_loc_copy.
    APPEND vs_toolbar_excluding TO i_toolbar_excluding.
    vs_toolbar_excluding = cl_gui_alv_grid=>mc_fc_loc_cut.
    APPEND vs_toolbar_excluding TO i_toolbar_excluding.
    vs_toolbar_excluding = cl_gui_alv_grid=>mc_fc_loc_paste.
    APPEND vs_toolbar_excluding TO i_toolbar_excluding.
