Query producing Dups

I swear I had this fixed but when I looked again this morning, I noticed that this query is producing dup records in the results. Something is not right with my query here:

SELECT DISTINCT m.customer,
c.name,
c.customer,
(SELECT Top 1 fd.Fee1 FROM FeeScheduleDetails fd
where c.feeSchedule = fd.code)
AS FeeSchedule,
m.Branch,
CASE WHEN ph.batchtype = 'PUR' OR ph.batchtype = 'PAR' OR ph.batchtype = 'PCR' OR ph.batchtype = 'DUR' OR ph.batchtype = 'DAR' Then
(-ph.totalpaid + ph.ForwardeeFee)
WHEN ph.batchtype = 'PU' OR ph.batchtype = 'PC' OR ph.batchtype = 'PA' OR ph.batchtype = 'DC' OR ph.batchtype = 'DA' Then
(ph.totalpaid + ph.ForwardeeFee)
END AS [Posted Amount],
ph.systemmonth,
ph.systemyear,
ph.datepaid,
ph.totalpaid,
ph.batchtype,
m.desk,
0 AS [NewCC_Amount],
0 AS [OldCC_Amount],
0 AS [NewPDC_Amount],
0 AS [OldPDC_Amount],
'In-House' AS Type,
1 AS Active,
m.number,
0 AS CC,
0 AS PDC,
m.original,
CONVERT(money, ph.OverPaidAmt),
0,
0,
'',
0,
0,
dc.OnHoldDate,
pd.OnHold,
(SELECT TotalPostingDays from TotalPostingDays),
(SELECT CurrentPostingDAy from CurrentPostingDay)
FROM dbo.Master m (NOLOCK)
INNER JOIN dbo.payhistory ph ON m.number = ph.number
LEFT JOIN dbo.DebtorCreditCards dc ON dc.number = m.number
LEFT JOIN dbo.pdc pd ON pd.number = m.number
INNER JOIN dbo.Customer c ON c.Customer = m.Customer
WHERE ph.systemmonth = datepart(mm, getdate()) AND ph.systemyear = datepart(yy, getdate())
AND ph.batchtype <> 'DA'
AND ph.batchtype <> 'DAR'
ORDER BY m.customer

Output:

Check out 00001, I am getting 2 $200, only should be getting one:

Can you provide some DB schema information, as it is hard to solve from that query alone. Usually you get duplicates because you are either missing one or more columns in your joins, or you have too many columns in your group by clause. Make sure all you joins use the Primary key column(s).

|||Did that help, or do you need more advice?
