     if screen-name = 'P_INPUT'.
        screen-invisible = '1'.
        modify screen.

Hi,

In your AT SELECTION SCREEN OUTPUT event,

LOOP AT SCREEN

chech if check box is checked then,

move 0 to checkbox-input.

MODIFY SCREEN

ENDLOOP

Hi,

Take a look at this thread.

Except that this thread talks about the selection screen the method to dynamically play with the components of the screen is still the same.

LOOP AT SCREEN.

MODIFY THE COMPONENTS.

ENDLOOP.

Ravi

AT SELECTION SCREEN OUTPUT.

LOOP AT SCREEN.

.........

MODIFY SCREEN.

EDNLOOP.

if u want to make any chenges in the screen display at run time, u can do in the above event.

"SCREEN" is a table containg fields like ACTIVE, INVISIBLE, INPUT, OUTPUT, REQUIRED etc.

check the table in dictionary and

see the fields, u can understand.

Hi long,

1. Its a little tricky.

2. we have to use two events.

at selection screen. (for detecting checkbox tick)

at selection screen output. (for showing disabled)

3. just copy paste in new program.

report abc.

data : flag type i.

*----

parameters : a(10) type c modif id M1.

parameters : chk type c as checkbox user-command ch.

*----

initialization.

flag = 1.

*----

at selection-screen .

check sy-ucomm = 'CH'.

flag = 1.

if chk = 'X'.

flag = 0.

endif.

*----

at selection-screen output.

loop at screen.

if screen-group1 = 'M1'.

screen-input = flag.

modify screen.

endif.

endloop.

regards,

amit m.
