Symptoms
After an 11.1.0.7 DataPump export from an 11.1.0.7 database, 11.1.0.6 DataPump import of the 
previously created dump file into an 11.1.0.6 database systematically fails with the following errors:

ORA-39002: invalid operation
ORA-31694: master table "SYSTEM"."SYS_IMPORT_FULL_01" failed to load/unload
ORA-02354: error in exporting/importing data
ORA-02373: Error parsing insert statement for table "SYSTEM"."SYS_IMPORT_FULL_01".
ORA-00904: "ORIGINAL_OBJECT_NAME": invalid identifier

Changes
Applied the 11.1.0.7 patchset on the source database.

Cause
This is caused by Bug:7590679. The column name ORIGINAL_TABLE_NAME was introduced in 11.1.0.7  
by the fix for unpublished Bug:5955150.

This issue reproduces when importing an 11.1.0.7 dump file into 11.1.0.6.

Solution
Upgrade both source and target on 11.1.0.7 will avoid this issue.

To solve this error, we suggest to:
1. Apply 11.1.0.7 Patch:6890831 on the target database.

Or:

2. Workaround this issue by re-running an expdp from the 11.1.0.7 database with an additional parameter
 VERSION=10.2. This will create a new dump file compatible to be imported into 10gR2, 
which will also import successfully into 11.1.0.6.

Unfortunately, please be aware that the new 11g specific features will not be exported 
if expdp is run from 11.1.0.7 with the parameter VERSION=10.2. 
If only normal objects and features are involved, this could be a good workaround.
