Hi Adham Enaya
Simple try like this
REPORT yram_SALV.
DATA: it_sflight TYPE TABLE OF sflight.
DATA: gr_table TYPE REF TO cl_salv_table.
DATA: gr_functions TYPE REF TO cl_salv_functions.
START-OF-SELECTION.
SELECT * INTO TABLE it_sflight FROM sflight up to 10 rows.
cl_salv_table=>factory( IMPORTING r_salv_table = gr_table CHANGING t_table = it_sflight ).
gr_functions = gr_table->get_functions( ).
gr_functions->set_all( abap_true ).
gr_table->display( ).
