Module pool screen

18 Views

Hi all,

I have developed a modulepool screen...this screen is used for saving vendor details into databse tables...so,here i m entering the vendor number and its details and then save it by using a pushbuton...My problem here is when i enter a vendor number and its detail values and suddenly if a user changes the vendor number...i need to show a message that u need to save vendor details before changing the vendor number..

How to achieve this..as the user first enters the vendor number and presses ENTER buton..then a event will trigger..but from there how to handle that event and how to know exactly the vendor number has changed....
