Matt,
You said that the best filter is on TM_DATE column. You did not say that which table or view the TM_DATE column is coming from in the view ps_rr_flat_vw. Is it the tm_eff_start_date column in the view ps_tm_peff_v_cc_vw (which in turn comes from PS_TM_PEFF_CONTRIB table).
I dont see how this filter applies to the tables in PS_TM_PEFF_V_CCEH. In your plan i see this TABLE ACCESS BY INDEX ROWID PS_TM_PEFF_GPQ, but in none of your view definitions, i see the table PS_TM_PEFF_GPQ.

regards
