Thankyou

Hi Imran,

              They maintained that I/O field attributes as "Invisible".

Hi Askar,

   May be they applied the below logic.

in module Output.

LOOP AT SCREEN.

     IF SCREEN-NAME = 'LPASWRD'.

       SCREEN-INVISIBLE = 1.

       MODIFY SCREEN.

     ENDIF.

   ENDLOOP.

so automatically the field will appear **** and at the same time while entering the data it will take as a ***.

Regards,

Krishna

Thanks for your reply....
Really helped me....

Is there any way to trigger an event ( PBO,PAI ) when the user enters a data in the I/O field?

Ex: I am having 5 fields,the 5th field is the total of the 4 fields.

when the user enters the values in any of the 4 fields the 5th field should show the total.
Is it possible??

( user wont be pressing any push buttons etc and this case POV wont be useful i tried )
Hope you can help me.

Thanks

Event 'On Data Change' can work. else you need to press enter to reflect the value in 5th field.

can you please tell me a brief about 'On Data Change' ?

[satyabrata_sahoo3]

In the PAI event, call the method CHECK_CHANGED_DATA. This method automatically triggers the data_changed event.
