Removing a Workflow Process Instance from Workflow Instance Monitor
If a Workflow Process instance contains a status of Stopped, Completed, Completed Abnormal or In Error, then you can remove it from the Workflow Instance Monitor view. If you must remove a Workflow Process instance that is paused, then you must first stop the instance.
Workflow Instances that are In Error are deleted regardless of the date you specify. All other status codes will use your specified date.
