SQL查询在连接到多个事务表时乘以总和结果

我正在编制一份报告，根据分配和取消日期衡量现金绩效。为了衡量这一点，我查询了一个transactions子查询，该子查询将收回所有交易，并根据账号和交易的起始日期和截止日期合并。然后在查询的顶部对其进行汇总

当使用一个子查询时，一切都很好，但是我现在必须添加一个额外的事务子查询；1计算从分配日期到取消日期或今天（如果值为空）的实际付款，2计算从分配日期+14天到取消日期或今天（如果值为空）的任何取消付款

第一个子查询工作得很好，但现在我添加了第二个子查询，它将求和值乘以8。我在过去两次尝试查询此表时都遇到过这种情况。不总是在8点之前。有什么想法吗

谢谢

总计这些TEST1的总和工作正常，TEST2没有那么多，子查询：

SUM(CASE WHEN v1.[Transaction Date1] >= dateadd(DD, 1, EOMONTH(getdate(), -1)) 
            THEN v1.[Payments] ELSE 0 
    END) AS TEST1,
SUM(CASE WHEN v2.[Transaction Date2] >= dateadd(DD, 1, EOMONTH(getdate(), -1)) 
            THEN v2.[Payments2] ELSE 0 
    END) AS TEST2,

我的代码：

         [Account Number1], [Transaction Date1], SUM([Payments1]) AS [Payments]

由于两个联接中最内部的subselect是相同的，所以应该将它放在顶部的WITH语句中，然后只使用两次。 像这样：

              ACCOUNTNO AS [Account Number2],
