Hi Nuno,

You can search the documentation for event AT SELECTION SCREEN.

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

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.
