example

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

Here you can find a simple report.

REPORT zcra_parallel2.

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??
