All About AT SELECTION-SCREEN OUTPUT Event With A Sample Code. This event gets triggered at the PBO of the selection screen every time the user presses “ENTER” button on the selection screen. In simple words, this event is triggered after loading the selection screen into memory but before it is displayed to the user. This event can be used to change the properties of the selection screen fields dynamically. Hence this event allows us to modify the selection screen and its fields directly before it is displayed. Attributes related to any selection screen fields are saved in a workarea called SCREEN during this event. In case you try to use two or more AT SELECTION-SCREEN OUTPUT events, you will get an error message “The event AT SELECTION-SCREEN OUTPUT was already specified in the program.” For example, if you select some radiobutton in the selection screen then you want some of the fields should become invisible or grayed out. Such scenarios can be achieved by using thi...
