possibilities for going back one or several steps?

[Wahl, Simone]

Hello,
 
I have a question considering a running workflow-system:
 
Which possibilities exist for changing a running workflow instance?
How can a user correct wrong inputs made one or several steps before?
I have only found the possibility to change the values of the container
elements for my existing workitems in my business workplace.=20
I haven't found the possibility to go back one or several steps to =
restart
the workflow at that point.=20
How is it possible to go back?
Who can help me?
 
kind regards
