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

Askar

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.
