Answer / guest

Cause: For a materialized view with UNION ALL to be fast
refreshable, it must have a UNION ALL marker column. This is
a constant column, at the same ordinal position in each
query block and must have distinct values in each query block.

Action: Add a UNION ALL marker column to each query block in
the UNION ALL query defining the materialized view.
