Nested Materialized View in 8.1.7

Hi, I am attempting to create a nested materialized view as per metalink doc id 212533 and I am hitting ORA-12015: cannot create a fast refresh snapshot from a complex query.
Please see my test script below:
Any help would be greatly appreciated
Thanks,

I have managed to execute my test script successfully in a different schema in the same database I was working with. Am I missing a grant?
I have been working as the schema owner in each of these schemas.
thanks,
