Hi,

Lets say that the FCODE of the clear button is CLEAR and let the name of the field be t_clear

And let the field group of t_clear be 'A'.

IN PAI write the below code.

IF SY-UCOMM = 'CLEAR'.            "checking whether the clear button is clicked.
t_clear = ' '.                                  "clearing the field

LOOP AT SCREEN.
IF GROUP1 = 'A'.                            "checking the group of the field

screen-input = 1.                           "making the field editable
MODIFY SCREEN.
ENDIF.
ENDLOOP.

ENDIF.

Hi,

Please assign FCODE to the button say DISA

In PAI

If gv_okcode eq 'DISA'.

Clear Field.

Loop at screen

if screen-name eq 'FIELD_NAME'.

screen-input = 0.

Modify Screen.

endif.

endloop.

endif.
