Hi,

For input parameters you need to press enter . The USER-COMMAND ucom will only work with checkboxes or radio buttons.

AT SELECTION-SCREEN OUTPUT is similar to PAI in screens. So you need some user action to trigger it (like pressing the ENTER key). If you use radiobuttons, then you can use USER-COMMAND option to trigger it.

Why do you want it this way? Why can't you show all of them?
