QSM-02175: some query block in UNION ALL MV is not fast refreshable..

Answer / guest

Cause: For a materialized view with UNION ALL to be fast
refreshable, each query block must conform to a fast
refreshable materialized join view or materialized aggregate
view.

Action: Check each query block in the UNION ALL to ensure it
is either a materialized view with joins or aggregates.
