How to get PAI triggered on date field of selection screen?

Hi Gurus,

I need to get the PAI triggered on date field of selection screen when user select date from drop down selection.

It does got triggered when user select date from drop down selection AND hit Enter or Any Key.

My requirement it to have it triggered even the user does not hit any key on keyboard, only by selecting date from DDL. As we use in Radio Button or Check Box of command USER-COMMAND.

Your help will be appreciated?
