12.2.0.1 impdp from 12.2.0.1 dumpfiles when parallel>1:ORA-31684/ORA-39111; ORA-39083/ORA-00054; ORA

Hello,

Recently I ran into 12.2.0.1 datapump schema level import errors (some appear to be "informational/ignorable" but some are not.

I'm having a SR open with Support -- so far the BDE team is trying to reproduce the same problem.

I wonder IF anyone out there has encountered the same.   If you do, please let me know. 

Thanks,

Joy

Below is my Scenario:

1. 12.2.0.1 database with following patches applied

27577866;

27589845;

25416731;

28163133;Database Jul 2018 Release Update : 12.2.0.1.180717 (28163133)

2. In 12.2.0.1 db, created the schema account only, and performed schema level import from 10.2.0.4 full export -- NO PROBLEM

3. Then take full export of the 12.2.0.1 db using the 12.2.0.1 datapump expdp.
