Database Software

Hello,
there is following workflow

CREATE TABLE test_sv(
ID NUMBER,
text VARCHAR2(100));

ALTER TABLE test_sv ADD CONSTRAINT test_sv_pk PRIMARY KEY (ID);

and made it version enabled.
i set a valid time and inserted a record: INSERT INTO test_sv (ID,text) VALUES (1,'feb 2006');

i set a valid time which didn't overlap the first one
and inserted a new one: INSERT INTO test_sv (ID,text) VALUES (1,'mrz 2006');

with the dbms_wm.export i wanted to export two records.

following result raised:
ORA-00001: unique constraint (EXPORT_VIETS.SYS_C00115680) violated
ORA-06512: at "SYS.LT", line 12625
ORA-06512: at "SYS.LT", line 12599
ORA-06512: at line 2

An experiment with the export_scpoe parameter raised an error.

Oracle Version 10.1.0.4

What is wrong on it. Is there a workaround?

Thanks and Greetings
