difference between at selection-screen and at
selection-screen output?
Answer Posted / the ajax
At selection-screen output is triggered when the selection
screen is loaded in memory before being displayed. The
event AT SELECTION-SCREEN is the basic form of a whole
series of events that occur while the selection screen is
being processed.The standard selection screen in an
executable program or in the logical database linked to it
is automatically called between the INITIALIZATION and
START-OF-SELECTION events. When you call the selection
screen, and when users interact with it, the ABAP runtime
environment generates selection screen events, which occur
between INITIALIZATION and START-OF-SELECTION.
