expdp does not export user jobs for MV refresh

Hi All,

I have Oracle standard 10gR2 which is having some MVs defined under schema "SchemaA".

CASE:1 expdp/impdp under SYSTEM 

I plan to move this to 11gR2 instance, initially I did expdp under SYSTEM account and did impdp with SCHEMAS=<SchemaA> and was failing with following errors:

ORA-39083: Object type REFRESH_GROUP failed to create with error:

ORA-23421: job number 454 is not a job in the job queue

BUT I DID SEE ERRORS FOR creating dbms_refresh jobs for ALL MVs.

CASE:2 expdp/impdp under SchemaA

As per the ML article suggestion, I now did expdp from the schema to be exported and did impdp into the 11gR2 instance under SchemaA (both instance have same schema name).
