Problem with a Nested Materialized View refresh.

-- Problem Statement:
ORA-942 during mview refresh process.

There is an mview based on another mview. We changed base table on master mview, so this parent mview
points to a new master table.
Dropping and recreating the child mview that reports ORA-942 fixes the issue.

Changes

The table on which the master mview was based was changed to a table with a different definition.
