I have a requriement where in I have to populate the input field on the screen based on the input in the other filed.
I have to input fields on the screen F1 and F2.
If the user enters "123" in F1 then 456 should be populated in F2 with out any button pressed.
Is there any event in ABAP for Input fields where in we can trigger our code based on some input from keyboard without doing/pressing any button.(Such as" if field value " or Field empty etc)
Kindly suggest how to proceed futher with this type of requriement.
Thanks in advance for all the suggestions and solution.
