Cannot CREATE UNIQUE INDEX; duplicate keys found

Question

I have 10g when I did an expdp from prod (an AIX 5.3 ) and impdp to a test (a RHEL3 ) with TABLE_EXISTS_ACTION=TRUNCATE, there are some index errors ORA-01452 for some of the tables but not all. As I compared the difference between , The only difference I noticed was that the one with error is the table has data, those tables without error have no data. So how which parameter I can use in impdp to avoid ? read the utility doc, have not found clear picture.

In 11510,
The duplicate row loaded is person 6272 with effective date 1994 and 1991. This needs to be fixed in vision.
Workflow SIL_PositionDimension_Full calls mapping SIL_PositionDimension to load target W_POSITION_D from source W_POSITION_DS. W_POSITION_D.INTEGRATION_ID maps to W_POSITION_DS.INTEGRATION_ID, but EFFECTIVE_FROM_DT is a more complicated many to one mapping.
Extract to W_POSITION_DS ;
SDE_ORA_PositionDimension_NonEmployee
- W_POSITION_DS.INTEGRATION_ID from PER_ALL_PEOPLE_F.PERSON_ID
SDE_ORA_PositionDimension_NoAssignments
- W_POSITION_DS.INTEGRATION_ID from JTF_RS_RESOURCE_EXTNS_TL RESOURCE_ID
