ORA-39221: Specifying data filters is invalid when dumpfiles do not contain table data.
Cause: A data filter was supplied for an import job, but the dumpfile does not contain any table data. The export command created a dumpfile with metadata only. No table data was included. From the command line, data filters can be specified by the CONTENT, SAMPLE and QUERY parameters.
Action: Do not restrict data handling on jobs that cannot support data filtering.
