You can check the value in the AT SELECTION-SCREEN event.

parameters:  p_field type c.

at selection-screen.
  if p_field is initial.
    message e001(00) with 'Please enter a value'. 
  endif.

start-of-selection.

May be this way

at selection-screen.
  if sy-ucomm eq 'ONLI'. "check when execute or f8 press
    perform f_check_bukrs.
  endif.

form f_check_bukrs.
  if p_bukrs is initial.
      message e999(yxxx) .
      " Invalid company code
    endif.
  endif.
endform.

Ok, but it is better to give a message to the user. But if you simply don't want to show the report, then you can use the STOP statement instead of the MESSAGE statement.

REPORT zrich_0001.

parameters:  p_field type c.

at selection-screen.
  if p_field is initial.
    stop.
  endif.

start-of-selection.

write:/ 'Report'.

Can't I use any LEAVE LIST-PROCESSING or something like that. I hope using STOP is not a good practice.

Ok..try like this...

DATA : mat LIKE marc-matnr.
PARAMETERS : p_matnr TYPE  marc-matnr.

AT SELECTION-SCREEN ON p_matnr.
  SELECT SINGLE matnr INTO mat FROM marc WHERE matnr EQ p_matnr.
  IF sy-subrc EQ 0.
    "do nothing
  ELSE.
    MESSAGE 'Enter valid material' TYPE 'S'.
    SUBMIT (sy-repid) VIA SELECTION-SCREEN.
  ENDIF

Geez, picky picky Kidding. How about this.

REPORT zrich_0001.

tables: sscrfields.

parameters:  p_field type c.

at selection-screen.
  if p_field is initial
       and  sscrfields-ucomm = 'ONLI'.
    sscrfields-ucomm = space.
  endif.

start-of-selection.


write:/ 'Report'.
