ORA-12015: cannot create a fast refresh snapshot from a complex query
Cause: Neither ROWIDs and nor primary key constraints are supported for complex queries.
Action: Reissue the command with the REFRESH FORCE or REFRESH COMPLETE option or create a simple snapshot.
As per oracle Error message information.
Give a try and back to this thread.
Cheers
