I'm having issues trying to select one row for each DonorConstituentID when more than one row exists with the same DonorConstituentID, DonorAmount and GiftDate.  I've tried TOP and RANK but can't seem to select just one of the rows where the three fields are the same.

With CTE as (Select g.DonorConstituentID, g.DonorAmount, GiftDate, APPEAL_ID, CAMPAIGN_ID, FUND_ID
From tblCCGiftsSoftCredit as g)
Select a.DonorConstituentID,  a.DonorAmount, a.GiftDate, APPEAL_ID, CAMPAIGN_ID, FUND_ID
FROM
(Select DonorConstituentID, Max(DonorAmount) as LargestGift, Min(Giftdate) as FirstGiftDate
from CTE
Group by DonorConstituentID) L LEFT JOIN CTE A ON  A.DonorConstituentID=L.DonorconstituentID and a.DonorAmount=L.LargestGift and A.GiftDate=L.FirstGiftDate
