按错误ssms分组，应该快速修复但无法找到它

Question

以下是我的查询。我在group by声明中收到错误，我无法弄清楚原因。我也包含了错误。

SELECT a.[Order Date]
    ,a.[Customer #]
    ,a.[Order #]
    ,a.[Order Type]
    ,OrderTotal
    ,CASE 
        WHEN c.OfferType IN ('Catalog')
            THEN 'Y'
        ELSE 'N'
        END AS 'Catalog Match'
    ,b.ChannelGroup
FROM LWPIM.dbo.MarketingReporting a
LEFT JOIN (
    SELECT sum([Total Price]) AS OrderTotal
    FROM LWPIM.dbo.MarketingReporting
    WHERE [Order Date] BETWEEN '2016-01-01'
            AND '2016-06-30'
    GROUP BY [Order Date]
        ,[Total Price]
    ) d
LEFT JOIN User_Sandbox.dbo.OfferCodeOfferType c ON a.[Offer Number] = c.OfferCode
    AND a.[Matchback Offer Number] = c.OfferCode
LEFT JOIN User_Sandbox.dbo.GAData2016 b ON a.[Order #] = b.Order_Number
GROUP BY a.[Customer #]
    ,a.[Order #]
    ,a.[Order Date]
    ,a.[Order Type]
    ,OrderTotal
    ,CASE 
        WHEN c.OfferType IN ('Catalog')
            THEN 'Y'
        ELSE 'N'
        END
    ,b.ChannelGroup
ORDER BY a.[Order Date] DESC
    ,OrderTotal DESC
