How To Pass Parameters In SSIS Dataflow

I am using a parameterized select query as displayed below to fetch values from source.

SELECT A.Account_GUID,
M.Merchant_GUID,
H.Household_GUID,
B.BankAU_GUID,
SR.SalesRep_GUID,
E.Entitlement_GUID,
I.Income_GUID,
Exp.Expense_GUID,
SP.Sales_Product_GUID,
P.Product_cd,
SUM(S.Sales) AS Monthly_gross_MC_VI_amt,
SUM(S.Sales) - SUM(S.[Returns]) AS Monthly_net_MC_VI_amt,
SUM(S.SaleTxns) AS Monthly_gross_MC_VI_tran_cnt,
SUM(S.SaleTxns) - SUM(S.ReturnTxns) AS Monthly_net_MC_VI_tran_cnt
FROM Account AS A
LEFT OUTER JOIN dbKAIExtract.dbo.tblSales_STG AS S
ON A.Account_No = S.AccountNo
And S.BucketNo = ? And S.ProductCode in ('01','02')
LEFT OUTER JOIN Merchant AS M
ON A.Account_No = M.Account_no
INNER JOIN SalesRep AS SR
ON SR.Rep_SSN = isnull(A.rep_SSN,'000000000')
INNER JOIN Household AS H
ON A.Account_No = H.Account_no
LEFT OUTER JOIN BankAU AS B
ON A.Assigned_AU = B.AU_No
LEFT OUTER JOIN SalesProduct AS SP
ON A.Account_No = SP.Account_no
And SP.Reporting_Interval_Id = ?
LEFT OUTER JOIN Entitlement AS E
ON E.Account_no = A.Account_No
AND SP.Product_Cd = E.Entitlement_Card_Type
LEFT OUTER JOIN Income AS I
ON I.Account_no = A.Account_No
And I.Reporting_Interval_Id = ?
LEFT OUTER JOIN Expense AS Exp
ON Exp.Account_no = A.Account_No
And EXP.Reporting_Interval_Id = ?
LEFT OUTER JOIN Product AS P
ON P.Product_cd = SP.Product_cd
WHERE (A.current_ind = 1)
AND (SR.current_ind = 1)
GROUP BY A.Account_GUID,
M.Merchant_GUID,
H.Household_GUID,
B.BankAU_GUID,
SR.SalesRep_GUID,
E.Entitlement_GUID,
I.Income_GUID,
Exp.Expense_GUID,
SP.Sales_Product_GUID,
P.Product_cd

My problem is, I am not able to assign any variables to parameterized query. Can any body guide how to assign respective variables to the parameterized query. I have the above query as a part of OLE DB Source step within Data flow task.
