Sql server TSQL Sum使用group by聚合多个列

Hi有三个表作为一个更大查询的一部分，我正在尝试为计算聚合一些值，但由于总和聚合是在group by发生之前对所有行进行合计，因此结果会加倍

表：

SR01

AC95

AC96

注意本例中的两行

质疑

结果

请注意，PrepTim、TravelTime和VisitTime的值未聚合且显示正确。当使用总和相加时，总数是11而不是5.5的预期值的两倍

考虑到这可能是由于AC96中有多行，我删除了Group By，显示了两行。这就是为什么总和aggreagte是该值的两倍

问题:

当AC96中有多行时，如何正确地定义查询以正确地求和，而不使数值加倍或更多？

请尝试此操作

;WITH cte_PreResult AS
(
SELECT DISTINCT 'Month' AS [Period],
    ISNULL(Zone.ZoneID,'') AS ZoneID,
    ISNULL(Zone.ZoneName,'') AS ZoneName,

    SR01.ReportKEy

    AND SR01.[Status]='X'
    AND SR01.RequestType <> 'MN' 
    AND SR01.DateComplete BETWEEN DATEADD(month, DATEDIFF(month, 0, @DateTo), 0) AND @DateTo
    AND (AC95.OnOffSite = 'ON' OR AC95.OnOffSiteSvc = 'ON')
    AND SR01.ServicingRep = @ServicingRep
)

SELECT  [Period],
        ZoneID,
        ZoneName,
        RegionCode,
        RegionName,
        BranchID,
        BranchName,
        ServicingRep,
        RepName,
        SUM(AC95.PrepTime + AC95.SvcPrepTime + AC95.TravelTime + AC95.SvcTravelTime + AC95.VisitTime + AC95.SvcVisitTime) AS HoursMonth,
        ReportKey
FROM cte_PreResult
GROUP BY [Period],
        ZoneID,
        ZoneName,
        RegionCode,
        RegionName,
        BranchID,
        BranchName,
        ServicingRep,
        RepName,
        ReportKey

虽然这样做是可行的，但我希望在主查询体中这样做，因为这是从更大的查询中提取的。这是可能的。只需将AC95.PrepTime+AC95.SvcPrepTime+AC95.TravelTime+AC95.SvcTravelTime+AC95.VisitTime+AC95.VisitTime添加为小时月，
