I think you misunderstood my message. I have a trigger in the SQL Server for Delete command. When a user wants to delete a records, this trigger is called (by SQL Server). The trigger updates several child tables. In my trigger code I still had the old table name that didn't need to be updated. Hence the error message. By commenting the "non-used" table name, the problem was resolved.
