Oracle Error Message
ORA-37418: detail query cannot be derived
Reason for the Error
If an ORANIZATION CUBE MV is to automatically derive its loading clause, then its definition query cannot contain set operators (eg UNION ALL), a HAVING clause, START WITH or a SQL MODEL clause. The definition query contains these or other unsupported syntax.
Solution
Use an explicit ORGANIZATION CUBE clause, or simplify the defining query.
