SELECT
QPDMADM.LAR_OMEGA_TRANS_SUM.SOURCE_TRANSACTION_ID,
QPDMADM.LAR_OMEGA_TRANS_SUM.ORDER_DATE,
QPDMADM.LAR_OMEGA_TRANS_SUM.SHIP_DATE,
QPDMADM.LAR_OMEGA_TRANS_SUM.FISCAL_PERIOD,
QPDMADM.LAR_OMEGA_TRANS_SUM.DISCOUNT_AGREEMENT_ID,
QPDMADM.LAR_OMEGA_TRANS_SUM.PRODUCT_ID_07,
QPDMADM.LAR_OMEGA_TRANS_SUM.CUSTOMER_ID_14,
QPDMADM.LAR_OMEGA_TRANS_SUM.ISO_COUNTRY_CODE2,
QPDMADM.LAR_OMEGA_TRANS_SUM.ACCOUNT_TYPE_CODE,
QPDMADM.LAR_OMEGA_TRANS_SUM.END_USER_CUSTOMER_ID,

QPDMADM.LAR_OMEGA_TRANS_SUM.INDUSTRY_CLUSTER_CODE,
QPDMADM.LAR_OMEGA_TRANS_SUM.SOURCE_SYSTEM_ID,
QPDMADM.LAR_OMEGA_TRANS_SUM.LOAD_DATE
FROM
QPDMADM.LAR_OMEGA_TRANS_SUM
WHERE
(
QPDMADM.LAR_OMEGA_TRANS_SUM.FISCAL_PERIOD = '200712'
)
GROUP BY
QPDMADM.LAR_OMEGA_TRANS_SUM.SOURCE_TRANSACTION_ID,
QPDMADM.LAR_OMEGA_TRANS_SUM.ORDER_DATE,
QPDMADM.LAR_OMEGA_TRANS_SUM.SHIP_DATE,
QPDMADM.LAR_OMEGA_TRANS_SUM.FISCAL_PERIOD,
QPDMADM.LAR_OMEGA_TRANS_SUM.DISCOUNT_AGREEMENT_ID,
QPDMADM.LAR_OMEGA_TRANS_SUM.PRODUCT_ID_07,
QPDMADM.LAR_OMEGA_TRANS_SUM.CUSTOMER_ID_14,
QPDMADM.LAR_OMEGA_TRANS_SUM.ISO_COUNTRY_CODE2,
QPDMADM.LAR_OMEGA_TRANS_SUM.ACCOUNT_TYPE_CODE,
QPDMADM.LAR_OMEGA_TRANS_SUM.END_USER_CUSTOMER_ID,
QPDMADM.LAR_OMEGA_TRANS_SUM.INDUSTRY_CLUSTER_CODE,
QPDMADM.LAR_OMEGA_TRANS_SUM.SOURCE_SYSTEM_ID,

This is not much you can do given all the facts.

One thing may help is to seperate this kind of reporting DW with the OLTP functionality of the db, which I'm assuming yours is.

For instance, nightly prepopulate data into a sum table, and redirect the query to get the where clause filter in real time.

What are you going to do with 70k rows?
