method WDDOMODIFYVIEW .
DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_alv_checkbox( ).
IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
  l_ref_cmp_usage->create_component( ).
ENDIF.
DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .
l_ref_interfacecontroller =   wd_this->wd_cpifc_alv_checkbox( ).
  DATA:
    l_value TYPE REF TO cl_salv_wd_config_table.
  l_value = l_ref_interfacecontroller->get_model( ).
DATA: lt_columns           TYPE          salv_wd_t_column_ref,
      ls_column            TYPE          salv_wd_s_column_ref,

        lt_columns = lr_column_settings->get_columns( ).
LOOP AT lt_columns INTO ls_column.
