Hi Nuno,

You can search the documentation for event AT SELECTION SCREEN.

Always try to search on google/SCN before creating a thread.

AT SELECTION SCREEN OUTPUT.

LOOP AT SCREEN.

IF SCREEN_NAME = 'pa_mon2'.

SCREEN-INPUT = 0.

pa_mon2 = pa_monat + 3.

MODIFY SCREEN.

ENDLOOP.

Hi Nuno,

Plz try the below code. Revert in case of issues:

tables screen.
PARAMETERS: pa_monat TYPE monat OBLIGATORY,

             pa_mon2 TYPE monat modif id 1,

             pa_gjahr TYPE gjahr OBLIGATORY.

at selection-screen output.

   IF pa_monat is initial.
     LOOP AT screen.
       if screen-group1 = '1'.
         screen-input = '0'.
       endif.
       modify screen.
     ENDLOOP.
ENDIF.

at selection-screen.
   pa_mon2 = pa_monat + 3.

Thanks

Hi Nuno,

     use the following code.

*initialization event block

INITIALIZATION.                                    "event block start

LOOP AT SCREEN.                              "loop at screen table till u get field name pa_mon2

     IF SCREEN-NAME = 'pa_mon2'.

          SCREEN-INPUT = '0'.                    "change input attribute to 0 making it non-editable by user

          MODIFY SCREEN.                        "update changes to screen table

          EXIT.                                             "exit loop

     ENDIF.

ENDLOOP.

""""""""""""""""""""""""""

  *at selection-screen event block

AT SELECTION-SCREEN.                         "event block starting

IF pa_monat IS NOT INITIAL.                       "check if pa_monat is filled with any data

pa_mon2 = pa_monat + 3.                           "change value of pa_mon2

ENDIF.

*press F8 for the processing after this

There is NO-DISPLAY option for PARAMETERS. But if the field is just calculated, why does it have to be a parameter at all? Doesn't make sense...

Overall I agree that is is a basic question. Please read ABAP Help and do some research before posting.
