Hi ,
First you have to create you own screen ( dynpro )  with a screen number ( 0101 for exemple )  , you need to pu a custom control in it , name the custom control ( lo_cont )
For the screen created you need to create a module for the PBO , in this module you sould put you code for displaying the liste :
Module STATUS_0101 output.
TRY.
lo_cont ?= lo_dock.
cl_salv_table=>factory(
exporting r_container      = lo_cont
             container_name = 'DOCK_CONT'
             list_display   = if_salv_c_bool_sap=>false
importing r_salv_table = gr_table
changing t_table = tbl_datos_items  ).
CATCH cx_salv_msg .
ENDTRY.
gr_functions = gr_table->get_functions( ).
gr_functions->set_all( abap_true ).
  gr_display = gr_table->get_display_settings( ).
  gr_display->set_striped_pattern( cl_salv_display_settings=>true ).
  gr_display->set_list_header( 'Items de Ventas' ).
  gr_table->display( ).
Endmodule.
and give the screen number when calling  lo_dock 
CREATE OBJECT lo_dock 
       EXPORTING
         repid = sy-cprog
         dynnr = '0101'.
