How to restrict 'parameters' value?

[Former Member]

Hi Masters!

In My program i have to use parameters and i have to declare a value, in the program itself using initialization.

Now my problem is, while executing the program the value in the parameters should be displayed but we should not able to change the value.

Can any one guide me please.

Hi Ganesh,

Try with this code:

PARAMETERS: pg_par1(5) .



INITIALIZATION.

   pg_par1 = 'hello'.

   LOOP AT  SCREEN.

     IF  screen-name = 'PG_PAR1'.
       screen-input =  '0'.
       MODIFY SCREEN.
     ENDIF.

   ENDLOOP.

Hi Ganesh,

You can set screen-input value to '0'  and modify screen inside the loop at screen.

INITIALIZATION.

p_val = 'SAP'.

AT SELECTION-SCREEN OUTPUT.

loop at screen.

  if screen-name = 'P_VAL'.

    screen-input = '0'.

    modify screen.

  endif.

endloop.

For that value you want to execute your program, make it default while declaring parameter.

PARAMETERS : p TYPE c DEFAULT  'A'.

AT SELECTION-SCREEN OUTPUT.

   IF p is NOT INITIAL.

     LOOP AT SCREEN.

      IF screen-name = 'P'.

        screen-input = 0.

        MODIFY SCREEN.

      ENDIF.

     ENDLOOP.

   ENDIF.
