Workaround

Don't use flashback. (we are using flashback_scn)
or
Grant flashback privileges directly to the expdp user for the eight failing Views until you can apply the patch:

grant flashback on SYS.KU$_USER_MAPPING_VIEW TO <expdp username>;
grant flashback on ORDDATA.ORDDCM_DOCS to <expdp username>;
grant flashback on SYS.FGA_LOG$FOR_EXPORT to <expdp username>;
grant flashback on SYSTEM.SCHEDULER_JOB_ARGS to <expdp username>;
grant flashback on SYSTEM.SCHEDULER_PROGRAM_ARGS to <expdp username>;
grant flashback on SYS.AUDTAB$TBS$FOR_EXPORT to <expdp username>;
grant flashback on SYS.DBA_SENSITIVE_DATA to <expdp username>;
grant flashback on SYS.DBA_TSDP_POLICY_PROTECTION to <expdp username>;
grant flashback on SYS.NACL$_ACE_EXP to <expdp username>;
grant flashback on SYS.NACL$_HOST_EXP to <expdp username>;
grant flashback on SYS.NACL$_WALLET_EXP to <expdp username>;
grant flashback on WMSYS.WM$EXP_MAP to <expdp username>;
Note:
This fix has been superseded by the fix in bug 19238926. For interim patches use that fix instead of this one.
