The ClearCase Eraser -- Versions Recorded in UCM Baseline

ClearCase UCM brings in more dependencies for the elements and ClearCase objects. It becomes harder to remove anything from ClearCase. Here in this blog shows how to remove a version that is "recorded in UCM baseline".

Before deleting the activity, we have to remove all the versions in the activity, -- if we do not want to move the versions to another activity.
