Use DBMS_MVIEW.EXPLAIN_MVIEW() to understand what you can do with this materialized view.

From the docs:

This procedure enables you to learn what is possible with a materialized view or potential materialized view. For example, you can determine if a materialized view is fast refreshable and what types of query rewrite you can perform with a particular materialized view.
