The hierarchy &V1& for characteristic &V2& contains &V3& entries in theinternal display format. Of these, the system automatically hangs &V4&leaves under the Not Assigned node.

System Response
The internal format uses a lot of memory both on the database and in themain memory.

If this value is notrequired, suppress the Not Assigned node. You do this ishierarchy maintenance by choosing Goto -> Hierarchy Attributes ->Suppressing Nodes Not Assigned.
