Received: <Object_id> has a materialized view log containing rowid's. If this table is reorganized, the materialized view log will have to manually recreated. Do you want to wish to remove this tables from the reorganization?
If the table that you're trying to reorg has material view logs, and the logs use ROWID, you may need to recreated after reorg. If you choose to reorg the table, then you've to recreate the material view logs manually after reorg is completed.
