The ALLSELECTED function gets the context that represents all rows and columns in the query, while keeping explicit filters and contexts other than row and column filters. This function can be used to obtain vi
Product[Brand] IN { "Contoso", "Fabrikam"} ) 我们建议读者自己测试的结果仅显示 Contoso 和 Fabrikam,它们是外部过滤器上下文中的品牌。 提醒一下,使用变量可以让代码在以后更容易编写和调试:必须习惯使用它们,因为它们在复杂的 DAX 代码中起着非常重要的作用。 至此,我们已经深入分析了 ALLSELECTED 用作单列表...
ALLSELECTED与影子筛选器作为DAX中最难的概念(可能没有之一)一直困扰着很多DAX学习者。在微软的官方帮助文档中(https://learn.microsoft.com/zh-cn/dax/allselected-function-dax),对于ALLSELECTED的解释很简单: (救命!为什么上传的图片这么模糊?) 对于大部分人来说,对ALLSELECTED的理解到此为止就足够了。简而言之,ALL...
译者注:ALLSELECTED 是一个如此复杂且充满陷阱的函数,以至于在 DAX 权威指南第一版面世的时候,对它的介绍仍然不够系统和完整,并且存在错误描述,后来作者已经对此做出了修正,最新的文章发布在这里,为了保证中文版内容的准确和完备,经作者同意,本节内容使用发表于 SQLBI 的《The Definitive Guide to ALLSELECTED》,原书...
DAX, I learnt that the ALL() function is the “remove filters” function. In fact, I still teach this concept to my students today. So as you may have guessed, the REMOVEFILTERS() function is actually just syntax sugar for the ALL() function that you can use when you want to remove...
ALLSELECTED merges two of the most complex behaviors of DAX in a single function: shadow filter contexts and acting as REMOVEFILTERS instead of a regular filter context intersection. For anyone wondering what the most complex DAX function is, now there is a clear winner: it is ALLSELECTED. Jul...
Sum Selected by Quarter:=CALCULATE(SUM(Table1[Qty]),ALLSELECTED(Table1),VALUES(Table1[Quarter])) I'm not sure what you'd like to calculate. What this measure do For the QuarterRank = 4 we have values in quarters 1 and 4 (returned by ALLSELECTED). ...

下面的示例演示如何使用 DAX 表达式在表报表中生成不同级别的直观合计。 在报表中,前面的两 (2) 个筛选器已应用于经销商销售数据;一个是 Sales Territory Group = Europe,另一个是 Promotion Type = Volume Discount。 应用筛选器后,就可以计算整个报告、所有年份或所有产品类别的直观合计。 此外,出于说明目的,...
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. Example The following example shows how to generate different levels of visual totals in a table report using DAX expressions. In the report two (2) previous filters ...
