ORA-12032

Error: ORA-12032: cannot use rowid column from materialized view log on "string"."string"

Causa: The materialized view log either does not have ROWID columns logged, or the timestamp associated with the ROWID columns is more recent than the last refresh time.

Acción: A complete refresh is required before the next fast refresh. Add ROWID columns to the materialized view log, if required.
