WHEN ‘SELECT_ALL’.
alv_grid_1->get_filtered_entries( IMPORTING et_filtered_entries = lt_filtered_entries ).
*        alv_grid_1->get_filter_criteria( IMPORTING et_filter = lt_filter ).
lv_index = 0.
LOOP AT gt_detail ASSIGNING FIELD–SYMBOL(<fs_detail>).
lv_index = lv_index + 1.
READ TABLE lt_filtered_entries INTO DATA(ls_filtered_entrie) WITH KEY table_line = lv_index.
IF sy–subrc <> 0.
<fs_detail>–chk_box = ‘X’.
