Parameter: {?CurrInvYear}   Example value = 2008

SQL Command:
SELECT     PART_ID, UNIT_PRICE, PURC_ORDER_ID, ORDER_QTY, LAST_RECEIVED_DATE, PURCHASE_UM
FROM         dbo.PURC_ORDER_LINE po
WHERE     (LAST_RECEIVED_DATE =
                          (SELECT     MAX(po1.LAST_RECEIVED_DATE)
                            FROM          PURC_ORDER_LINE AS po1
                            WHERE      po1.PART_ID = po.PART_ID AND LAST_RECEIVED_DATE < '01/01/ 2008'))


Can I pass the Parameter to the last line of the SQL Command instead of hard coding 01/01/2008

Like:
AND LAST_RECEIVED_DATE < '01/01/ ‘ & {?CurrInvYear}   ))


OR is there a way to return the max LAST_RECEIVED_DATE < '01/01/ ‘ & {?CurrInvYear}  without the use of a SQL Command?
This report takes 80mins to run because of the SQL command

I can't select for this because one field is the last date prior to {?CurrInvYear}  or 2008 and another is the last date prior to {?CurrInvYear} -1  or 2007

does it take that long using SQL server?  if so, nothing is going to help.
