Oracle Solution for Error ora-12071

ORA-12071: definition query of "string"."string" is invalid for offline instantiation

What triggered the Error:

Offline instantiation requires materialized view definition queries to observe the following constraints: *o The database link that will be used by the materialized view site to connect to the master site must be included with each master table referenced in the query. *o All master tables referenced must be located at the local site. References to other sites are not allowed.

What should we do to fix it:

Modify the materialized view definition query.
