Well, you'll definitely be wanting to enable star transformations. Try that and see what happens.

What column are you partitioning on, and by what method? If it is by SERVICE_CASE_PROCESS_DATE_KEY then I doubt that you're getting the partition pruning that you deserve.

Is this query generated by some tool or other? I'm intrigued by the complex in-line view you have in there.
