example

comibining parallel processing (CALL FUNCTION STARTING NEW TASK) with the ABAP OO concept of events.

Here you can find a simple report.

METHOD start.

CALL FUNCTION 'ZZ_CRA1' STARTING NEW TASK i_taskname

CALLING me->receiver1 ON END OF TASK

EXPORTING

mytask = i_taskname.

IF sy-subrc = 0.

WRITE: /, i_taskname, ' TASK started...'.

ENDIF.

ENDMETHOD. "start

METHOD receiver1.

DATA:

myinfo TYPE TABLE OF zcra1.

Hi Arvish,

You can use the generic type CLIKE only with field-symbols and formal parameters. You might have noticed that during the syntax-check. So I guess, its better to go for field-symbols if you need a generic variable.

Can you elaborate a bit more on why you really need to go for a generic type??
