Wish to include Posting Periods rather than hard coded Dates

Question

Hi Guys,
I have this query that I would like to have it look for the financial year based on the posting periods rather than hard code in the year - i.e 2011. The reason being that the financial year is from 1st October to 30th September, so my query below will not give me accurate information when going from December to January as the Year is Hard Coded in currently.
Does anyone have any ideas how I can achieve this, I must admit to be totaly stuck.
Kind regards
Sean

Hi Sean,
Even though it is possible to use variable for the report, I would suggest hard coded like this because you have different financial year with calendar year:
SELECT P.CardCode,P.CardName,
(SELECT SUM(Debit) - sum(Credit) FROM JDT1 WHERE ShortName= P.CardCode AND DueDate>= '10/01/2010' AND DueDate<= '09/30/2011' AND TransType IN ('13','14')) '2011 Sales',
[10] as '10-10',
[11] as '10-11',
[12] as '10-12',
[1] as 'January',
[2] as 'February',
[3] as 'March',
[4] as 'April',
[5] as 'May',
[6] as 'June',
[7] as 'July',
[8] as 'August',
[9] as 'September'
FROM (SELECT T0.CARDCODE, T0.CARDNAME, (T1.Debit - T1.Credit) AS BAL,
MONTH(T1.Duedate) as month
FROM dbo.OCRD T0
LEFT JOIN dbo.JDT1 T1 ON T1.ShortName = T0.CardCode AND T1.DueDate>= '10/01/2010' AND T1.DueDate<= '09/30/2011'  AND T1.TransType in ('13','14')) S
PIVOT (SUM(S.BAL) FOR month IN
([1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12])) P
Thanks,
