What I am trying to write:
DAX度量将输出数量，如结果列中显示的量 . 如果我在哪里写一个linq查询来选择正确的速率，它将看起来像这样：
LaborRate = db.Rates
.Where(a => a.DateFrom <= SelectedDate & a.DateTo >= SelectedDate & a.RateType == "LaborRate")
.Select(a => a.Amount).Sum();
我尝试过CALCULATE，SUM，SUMX，FILTER，RELATED的组合，但我无法让它工作 . 任何建议将不胜感激 . 什么是最简单的方法？

通过执行以下操作，我能够实现此目的 .
将
Month = MONTH(Qty[Date])添加为Qty表的计算列 .在
Qty表中创建TotalLaborQty度量为SUM(Qty[LaborQty]).在
Rates表中定义LaborRate度量，如下所述 .将
Result度量定义为[TotalLaborQty] * [LaborRate].将它们设置在一个矩阵中，行中有
Qty[Location]和Qty[Month]，三个度量作为值 .
