Restart workflow with keeping log

[HILVEN Wim (ITG/ASG)]

Hello,
 
I am trying the following:
 
Our user should be a able to change a request he has submitted while the
workflow is running.  The request is a business object (subtype of
PDOTYPES).
So the current workflow should be stopped and restarted from scratch keeping
the workflow log.
 
Any idea how this can be accomplished?
 
P.S. Can you use tx SWPR only for restarting faulty workflows?
 
 
Many thanks,
Wim
