如何使用 DAX Power BI 添加组内每一行的总和

How to add total sum of each rows within group with DAX Power BI

我试图给出每个组的排名列,这些列在原始 table 组内的每一行中重复,但不是汇总后的形状。

我在另一个网站找到的公式,但显示错误: https://intellipaat.com/community/9734/rank-categories-by-sum-power-bi

脚本

sum =

SUMX(

    FILTER(

         Table1;

         Table1[product] = EARLIER(Table1[product])

    );

    Table1[sales]

) 

错误:

EARLIER(Table1[product]) # Parameter is not correct type cannot find name 'product' 

上面的脚本有什么问题? * 无法测试此脚本:

rank = RANKX( ALL(Table1); Table1[sum]; ;; "Dense" )

之前固定总和方法

脚本是为计算列设计的,而不是度量。如果您将其作为度量输入,则 EARLIER 没有 "previous" 行上下文可供参考,并给您错误。

创建度量:

Total Sales = SUM(Table1[sales])

此度量将用于显示销售额。

创建另一个度量:

Sales by Product =
SUMX(
  VALUES(Table1[product]);
  CALCULATE([Total Sales]; ALL(Table1[date]))
)

此度量将显示按产品忽略日期的销售额。

第三招:

Sale Rank = 
  RANKX(
     ALL(Table1[product]; Table1[date]); 
     [Sales by Product];;DESC;Dense)

创建一个以产品和日期为轴心的报表,并将所有 3 个度量放入其中。结果:

如有必要,调整 RANKX 参数以更改排名模式。
