Well I wanted to get details about the events in reporting/interactive... and the statements which trigeer those events.
 
Event related to reports are not triggered based on any statements in ABAP. 
The event are triggered depended on the way the output is generated . 
for eg:
Initialization : triggered when the report is loaded in memory.
At selection-screen output : triggered when the selection screen is loaded in memory before being displayed.
At selection-screen / <field> : before leaving the selection screen.
start-of-selection : the first event for displaying the report.
end-of-selection : after the start-of-selection is completed.
classiscal report events.
top-of-page : every time a new page is started in the list.
end-of-page : every time the list data reaches the footer region of the page.
interactive report events.
top of page during line selection : top of page event for secondary list.
at line-selection : evey time user dbl-clicks(F2) on the list data.
at pF<key> : function key from F5 to F12 to perform interactive action on the list.
