Oracle Error Message
ORA-33247: (CRENAME03) %K is already a value of the dependent UNIQUE concat dimension workspace object, from leaf dimension workspace object.
Reason for the Error
A value cannot be renamed in a dimension if the new value conflicts with an existing value in a unique concat dimension containing this dimension.
Solution
The concat(s) causing the conflict could be CHGDFNed to NOT UNIQUE, or either of the duplicate values could be changed to make them UNIQUE.
