Oracle : Ошибка ORA-32331

"type \"%s\".\"%s\" is incompatible with the master site"
*Cause: A type used by the materialized view was found to be
incompatible with its coressponding type on the master site.
This could be because the type does not exist on the master site
or has been evolved to a different version from that on the
materialzied view site.
*Action: Make sure that the types used by the materialized view are the
same on both the materialized view and master sites.
