Use the Position Hierarchy window to delete a position hierarchy. You must check that the hierarchy is not tied in to other working areas of the system before you try to delete it.
Remove any subordinate positions from the hierarchy, starting at the lowest level.
Check whether other versions of the hierarchy exist. If they do, you must delete these other versions first.
Check whether the position hierarchy is referenced by a security profile. If it is, you must first delete this link.
Query the position hierarchy in the Position Hierarchy window and choose Delete.
