While the database server was reconstructing a table from the audit trail, it found a discrepancy between the contents of an updated row now and the contents that were recorded in the audit trail when the row was first updated. Either the audit-trail file has been corrupted, or the audit-trail file is incomplete, with missing records for some alterations. The table cannot be recovered as it stands. Try the operation again after you make sure that the table has been restored to exactly the state it had when the audit trail was created. If the error recurs, rebuild the table by other means.
