What is the need of END-OF-SELECTION event in ABAP reporting

Question

Hi,
Can anyone explain the need of the END-OF-SELECTION event in ABAP Reports?
This event is used to terminate the previous event. Is that right? or is there any specific use of it?
and when exactly we use this event while writing a report? I mean what purpose?
Thanks,
Paddu.

Hi,
END-OF-SELECTION makes more sense when you are using logical database in your program.
See these links.

After all the data has been selected END-OF-SELECTION event writes the data to the screen
The END-OF-SELECTION event is triggered in executable programs once the logical database has finished reading all data and before the list processor is started.

Mostly end-of-selection is used in logical data base. It is not mandatory.
Ex:
If you use a logical database in your report then this event is mandatory because when all the data selection from the database is finished this events get triggers.
For example if you are populating a internal table using a logical data base event 'GET' then you need this event because if you don't use this you get display again and again for each selection.
START-OF-SELECTION.
GET PERNR.
itab-pernr = pernr-pernr.
append itab.
*this get triggers after all selection from database.
END-OF-SELECTION.
loop at itab.
write:/ itab-pernr.
endloop.
