Deleting workflow instances on production

[Dart, Jocelyn]

Hi Fred,
Better to write a program to logically delete the offending workflows via the top workflow instance id en masse and then archive them. If you just delete using SWWL there is a significant risk of orphaned work items as the deletion program doesn't check that you have cleanly removed all work items related to a particular workflow instance.
 
If you don't have a WAPI for this in your release (i.e. if you are in a non-WAS system) use function module
SWW_WI_ADMIN_CANCEL to logically delete the top workflow instance work items once you have identified them.

Subject: Deleting workflow instances on production
 
 
Hello,
 
I know I can delete work items using tx SWWL. I also know it is not
advised to do this in a production client. But we have a situation in
which many (thousands of) workflow instances have been started, which
shouldn't have been started (a job has run which has created change
documents for which a workflow is triggered, we didn't think of this in
advance).
 
My question is: what is the right strategy to delete these workflow
instances? Just running SWWL for the complete selection? Delete them
group by group? I'm not sure how long it will take to delete them and
the problems this can cause. All advise is welcome!
 
Regards,
 
Fred Kouw
