Materialized Views - Query Rewrite Not Working

Hello,



I have two tables and each has a materialized view. If I select an
aggregated value from either table, it's materialized view is used and query
rewrite works fine.



These tables are of similar structure and I also have a view sitting on top
of them, which "union all"s them together.



If I select the same aggregated value from this view, there is no query
rewrite.



Any ideas?



Cheers,


AB.
