ORA-942 on Materialized View Refresh after Master Mview Recreated on Different Table (Doc ID 867042.1)

Last updated on MAY 12, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 10.1.0.2 to 11.2.0.2 [Release 10.1 to 11.2]
Information in this document applies to any platform.

Symptoms

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.
