Background tasks and deadlines

[Sample, Rick]

Hi Margaret,

Never used it before, but I just tried it. Nope! Does not stop the task or the BOR-Method process. 
When I Logically Delete the WF task, the program still continues to run, until I kill it in SM50. 

I am looking for the config for time outs. I believe there is an SWU3 setting. Forces long running "Oops loops" into error if they take longer than 'X' time. As Mike stated, supposed to be 30 mins default. (as I recall anyway). I have been away from SAP for 6+ months, so little rusty and doing the hunt & peck method of finding this setting.

Thanks - and if you know where these settings are to set WF tasks or 'stuck in loop' processes to error, please forward. 
Rick

Rick,

I don't know if this was mentioned yet ... in the workflow step definition, scroll far to the right, on the Miscellaneous tab, there is a setting labeled "Time from Creation of Work Item Until Timeout". The help for this field says, "Time interval between the creation of the background work item and the occurrence of the timeout."

Have you tried this?

Thanks for assistance all.

No success. And one more question. 

Mike, on your point on the 30 minute error rule. That is obviously not working here. These looped task will run for days if I let them. So would you be so kind as to remind me where that setting is located? I recall a setting, but can't recall what / where. 

First, until I can figure out why code that has been working correctly for 6 yrs is now 'sometimes' getting stuck in loop, I would like to stop the bleeding. 

Tests:
I created a simple test WF with BG task and simple DO forever loop. 
I tried everything that I can think of (and suggestions from list) to stop this task and running process in SM50. 
Parallel fork suggestion, continues the flow, but does not stop the said BG Looped task. Async with term event, nada. Deadline, nope!

Persn'ly I'd consider the wrong approach.

Deadlines aren't meant for this level of control. The timing resolution is a 5 minutes accuracy at best, and background tasks error after 30 minutes by default (at least last time I looked). If a background task takes that long it should probably be asynch anyway.

Best off doing this in code - add a timer to whatever the task method does
- e.g. in a loop. Use SELECT ... PACKAGE SIZE nnn to break up a long-running query - it would even improve DB performance if it means you can stop a query gracefully whever it takes too long.

Otherwise I suppose one could create a 'Meta method' that submits a task and monitors it in a WAIT UP TO... loop. Not pretty but an option.

Regards,
Mike
