Question

我有一个FactLosses表和一个DimAccumulation表。我已将它们带入PowerBi并且我已经放置了一个切片器来选择我感兴趣的累积区域。

一旦用户选择了区域，我想逐年对损失进行分组，并将损失汇总到年度分组中。但仅适用于适用于用户选择的区域的数据。

我正在使用以下DAX代码来完成这样的组...

表= SUMMARIZECOLUMNS（FactForwardLookingAccumulation [年]，“按年损失”，SUM（FactForwardLookingAccumulation [净亏损我们的股票分享]））

问题是新表总是产生相同的结果。即当我改变应该包括哪些累积危险时，它对总和没有影响。（它是对整个表的总结）

我想使用切片器过滤事实表，然后在过滤后的列表上运行DAX查询。这可能吗？

Answer 1

如果您希望这些表对报表上的过滤器或切片器做出响应，那么您不能将这些表写为显示在“数据”选项卡下的计算表，因为这些表是在任何过滤发生之前计算的。

为了获得你想要的东西，你必须在一个尺度内做所有事情，因为那些是对切片机的反应。如果您在分组和求和完成后正在寻找最大损失年份，您可以按以下方式编写一个度量：

以这种方式编写将允许计算表响应切片器和过滤器。

是否可以使用切片器作为DAX Summarize函数的参数？
