This post shows you details about a specific case where 'hash anti join' is defeated by 'nested loop anti join'.
The initial problem came to light in a very large BW system running on Oracle 11.2.0.4 when several BW loads (making use of older data in the BW system) reported missing dimension ids in the dimension tables.
