Formatting Selection Screens 

The selection screen that you define when you use the PARAMETERS or SELECT-OPTIONS statements on their own, has a standard layout in which all parameters appear line by line. This layout is not always sufficient. For example, when you define a group of radio buttons, you should set off these buttons against other input fields so that the user can identify them as a group.

The SELECTION-SCREEN statement has its own formatting options that you can use to define the layout for selection screens. You can define the layout of parameters and selection criteria and display comments and underlines on the selection screen. In addition, you can place pushbuttons in the application toolbar and on the screen itself.

You can only see the layout of a selection screen if you call that screen. However, standard selection screens in executable programs are only called if they contain at least one input field declared using the PARAMETERS or SELECT-OPTIONS statements. This means that it does not make any sense to place comments, underlines or pushbuttons on a standard selection screen without including at least one input field. User-defined selection screens, on the other hand, can be called even if they do not contain an input field. In this case, you can use all formatting options, in particular pushbuttons, on selection screens without input fields.
