Qtn:Why we have to write the start-of-selection event in object oriented programme?

Hi,

See here http://help.sap.com/abapdocu_70/en/ABAPSTART-OF-SELECTION.htm

"In the third program, there is no explicit processing block. All statements implicitly form the event block START-OF-SELECTION."

Regards.

Hi,

Start-of-selection is just one of the standard events in ABAP reports.

A report can used object-oriented code (or not); this does not affect the use of start-of-selection..

I'm curious - why do you ask?

cheers

I believe your issue can be demonstrated using this snippet which does not compile without addition of start-of-selection.

1. *----------------------------------------------------------------------*
2. CLASS mainclass DEFINITION.
3.   PUBLIC SECTION.
4.     CLASS-METHODS main.
6. ENDCLASS.                    "mainclass DEFINITION
7. *----------------------------------------------------------------------*
8. CLASS mainclass IMPLEMENTATION.
9.   METHOD main.
10.     WRITE 'hello'.
11.   ENDMETHOD.                    "main
12. ENDCLASS.                    "mainclass IMPLEMENTATION
14. START-OF-SELECTION.
15.   mainclass=>main( ).

Hi,

You can also create Transaction type: Object transaction.

I did not had the chance to check this .
