Hi geeta,
<b><i>In report programs</i></b>
First event -
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 : before leaving the selection screen.
start-of-selection : the first event for displaying the report.
This event keyword defines an event block whose event is triggered by the ABAP runtime environment
when calling the executable program selection screen processing of a selection screen.
In an executable program, all statements that are not declarations,
and are listed before the first explicit processing block, are assigned to this event block.
If the program does not contain an explicitly defined event block START-OF-SELECTION,
these statements form the complete event block START-OF-SELECTION.
If a program contains an explicitly defined event block START-OF-SELECTION,
these statements are added to the beginning of the event block.
If the program contains no explicitly defined event blocks,
these statements form the entire event block START-OF-SELECTION.
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.
at user-command

<b>dilog programming events</b>
PBO event
This event is triggered before the screen is displayed. The processing of screen before the display of screen is done in this event. For example, filling in default values in the screen fields.
PAI event
This event is responsible for processing of screen after the user enters the data and clicks the pushbutton. The processing of screen can include displaying another screen, or just displaying list or quitting the transaction itself and many more things. Usually it is displaying another screen. These operations can be carried out in the PAI event. OKCODE plays an important role in this operation.
POV event
Process on value request is triggered when the user clicks F4 key. You can handle this event when the user presses F4 key by writing code for the same in module pool program. Normally when the user presses F4, list of possible values is displayed. The standard list produced by system is adequate for applications you develop yourself. However, you can also have the option of setting up your own documentation and lists of possible values that are more detailed.
POH event
Normally when the user places the cursor on the field and presses F1 function key, the system displays its own Help for that particular field. You can add your own functionality to the Help button by writing code for the same in the POH event.
