actually .. at line-selection is an event which is
trigerred when ever u double click a record line in the
primary list.... or single click onthe record if u using
HOTSPOT command....
so when this event is triggered it will fetch that row's
information in the system variable SY_LISEL...as it is
displayed on the screen....

information only which u want....

fields only which u want.... simple

mainly this event is used whenever we r using lists...
