How can I determine if an error is a corrupt workflow definition?

I am getting this error message in my workflow:

"No successor defined for node XXXXX and Result 0000"

The user has just made a decision using the standard decision task and the result in the container is "0001." What does the error message mean?

The message doesn't sound good. Possibly, it's a corrupt workflow definition. Try clearing the buffer and see if that helps the problem. Otherwise check for an existing note in OSS, or log an OSS message with SAP.
