Select multiple lines in ALV list

Question

Hi Everyone,
I have an ALV list which has checkboxes. Now when we select the check boxes and press enter it should  take me back into the program with only those lines in an internal table for which the checkboxes have been clicked. Is this possible.
Any input is greatly appreciated.
Thanks
Kumar.

yes... perhaps it is in how you are processing it. i am NOT using hotspots. i created a GUI status with a icon, and assigned it to a specific OK_CODE. then, when you display the ALV,
  call function 'REUSE_ALV_GRID_DISPLAY'
    exporting
      i_grid_title             = w_alv_title
      is_layout                = t_alvlayout
      it_fieldcat              = t_alvfieldcat
      it_events                = t_alveventcat
      it_sort                  = t_alvsortcat
      i_save                   = i_save
      is_variant               = default_layout
      i_default                = 'X'  " Allow Display Variants
      i_callback_program       = w_alv_callback_prog
      i_callback_user_command  = w_alv_command_handler
      i_callback_pf_status_set = w_alv_gui_status_setter
      i_callback_top_of_page   = 'STANDARD_LIST_HEADING'
    tables
      t_outtab                 = t_alvdata
    exceptions
      program_error            = 1
      others                   = 2.
you specify a command handler callback, with the callback program and form
  w_alv_command_handler = 'ALV_COMMAND_HANDLER'.
  w_alv_callback_prog = sy-repid.
then the handler would do something like this
form alv_command_handler using r_ucomm like sy-ucomm
                           rs_selfield type slis_selfield.
  read table alvdata into alvline index rs_selfield-tabindex.
  case r_ucomm.
    when 'DELETE'.
* make sure at least one line was selected
      read table alvdata into alvline with key select = true.
      if sy-subrc <> 0.
        message i014.
      else.
        call function 'POPUP_TO_CONFIRM'
          exporting
            titlebar              = 'Delete Confirmation'
            text_question         = 'Are you sure?'
            text_button_1         = 'Yes'
            text_button_2         = 'No'
            default_button        = '2'
            display_cancel_button = ' '
          importing
            answer                = answer
          exceptions
            text_not_found        = 1
            others                = 2.
        if sy-subrc = 0 and answer = '1'.
          loop at alvdata into alvline where select = true.
            perform delete_a_message.
          endloop.
* refresh the list data
          perform load_alvdata.
          rs_selfield-refresh = true.
        endif.
      endif.
    endif.
* process hotspots
    when '&IC1'.
      case rs_selfield-fieldname.
        when 'FILENAME'.
          submit ylo_newbreed_message_edit
            with p_file = alvline-filename
            with p_change = ' '
             and return.
        when 'LASTSTS'.
          perform display_messages.
      endcase.
  endcase.
endform.                    "alv_command_handler
i cut a lot fo code out of this, so it may be missing some endif or whatever, but as you can see, you check the ok code, and if it matches your GUIstatus button, you loop over the internal table and process the data
sorry for the long reply. i hope it helps
