Hi pawan,

u may have added the fields using module pool programming..ther itself for that particular screen in which u have done the modification, u need to write the code in PAI(process after input)... eg, ur push button is identified with an ok_code name say 'PB'

so u write.

case sy-ucomm.

when 'PB'.

do something..

endcase..

similarly...an i/o box is identified by its name u ve specified....

Hope it helps,

hi

i have done like this.

in PAI module of subscreen.

IF SY-UCOMM = 'BTN'.

NAME = 'ABC'.

ENDIF.

NAME is the I/O box name. BTN1 is the function code for button. i activated everything including the enhancement project. even then, i dont see any 'ABC' when i press the button.

what could be the reason?

Hi pawan,

when any action is caused on the screeen such as button press, sy-ucomm contains the function code.

Check for this in PAI event of the screen in user-command module.

case sy-ucomm.

WHEN 'F_code of the button pressed'.

....

endcase.

Hi,

If you have used screen exit to add more fields on a standard screen then you can write the code in function module exit in the same enhancement (SMOD object). FYI, every screen exit will have corresponding function exit(s) to perform input validation and to pass the data between main screen and screen exit.

If you want to validate the data from main screen also, then check for the existence of any other user exit that will triggered on the screen action/or at the end of the transaction.

If you have modified the standard screen itself to add the new fields, you have full control to play with the standard program itself as have already give the access key for changing it, so write your code in PAI of the screen.

Hope this helps.
