Hi friends,

Let

   
PARAMETERS : name(10) .
write : name.

Now if in the selection screen , we give , say qwerty and execute it , we get qwerty in the screen .

here if the back button is clicked the initial screen selection screen appears with the value qwerty filled in it.What is the reason for this ? How to make the parameter space empty in selection screen when the back button is clicked .

Regards,

K.Sibi

write like this


PARAMETERS : name(10) .
start-of-selection.
write : name.

the following write was called when the event at selection screen was triggered. this will work fine.

Hi Sibi,

Use at selection-screen event.

Under the event write coding

AT SELECTION-SCREEN.

CLEAR NAME.

Hope it will be useful.

Hello sachin and vinod,

Thanks for your replies.

It is working fine, as long as i give input in selection selection screen and press F8.

but if i press enter , the values get deleted on the screen itself.

Hope to get it cleared.

Regards,

K.Sibi

Hi,

Whenever 'Enter' is pressed in selection-screen, 'At selection-screen output' event will execute.

To add:

'At selection-screen output' event is executed at PBO of the selection screen every time the user presses ENTER - in contrast to INITIALIZATION.

Therefore, this event is not suitable for setting selection screen default values.
