Restarted workflow does not continue

[Michael Pokraka]

Hi Fred,
SWU_OBUF resets SAP's HR/workflow buffers - usually this happens at midnight, but is sometimes necessary after a transport. I was referring to your comment about SAP 'remembering' - so it's a similar effect.
I think if you switch from a foreground to a background task you may need to transport the entire WF definition. As a safe approach, I'd even suggest removing and readding a task for this type of change.
 
Cheers
Mike
