Regarding Buttons Functionality in INPUT FORM

Hi,

we can add some buttons for the Input Form, Say, we had a requirement to type Employee Number and CREATE,CHANGE,DISPLAY Infotype Record.

I can add 3 buttons in the INPUT SCREEN. But now, I want to call 3 different RFC Enabaled Function modules as per the button chosed.

Can anyone let us know whethear this is possible?

Regards,
