Query taking more than 1/2 hour for 80 million rows in fact table

Question

Hi All,
I am stuck in this query as it it taking more than 35 mins to execute for 80 million rows. My SLA is less than 30 mins for 160 million rows i.e. double the number.
Below is the query and the Execution Plan.
SELECT txn_id AS txn_id,
acntng_entry_src AS txn_src,
f.hrarchy_dmn_id AS hrarchy_dmn_id,
f.prduct_dmn_id AS prduct_dmn_id,
f.pstng_crncy_id AS pstng_crncy_id,
f.acntng_entry_typ AS acntng_entry_typ,
MIN (d.date_value) AS min_val_dt,
GREATEST (MAX (d.date_value),
LEAST ('07-Feb-2009', d.fin_year_end_dt))
AS max_val_dt
FROM Position_Fact f, Date_Dimension d
WHERE f.val_dt_dmn_id = d.date_dmn_id
GROUP BY txn_id,
acntng_entry_src,
f.hrarchy_dmn_id,
f.prduct_dmn_id,
f.pstng_crncy_id,
f.acntng_entry_typ,
d.fin_year_end_dt
Execution Plan is as:
11 HASH JOIN Cost: 914,089 Bytes: 3,698,035,872 Cardinality: 77,042,414      
                                                                                9 TABLE ACCESS FULL TABLE Date_Dimension Cost: 29 Bytes: 94,960 Cardinality: 4,748

Kindly suggest, how to make it faster.

The above is just a part of the query that is taking the maximum time.
Kindly find the entire query and the plan as follows:
