You can't use the RELATED() function, because more than one row could be related. Using the ALL() function on a table doesn't remove filters that are applied to other, related tables by a many-to-many relationship. In the preceding example, a measure that's defined as shown here woul...
available, many-to-many relationships are commonly encountered, and they can pose significant challenges. In this article, we will dive deep into the world of Power BI relationships, explore the ins and outs of many-to-many relationships, and provide practical tips and alternatives to avoid them...

RELATED(<column>)下面是我们演示数据的表格和关系，已经使用了很多次了，一个销售数据表，一个产品维度表和一个日期维度表。关系如下↓ 第一个功能和Excel里面Vlookup一样，也和上一篇讲的lookupvalue函数类似。但因为我们在表之间建立了关联关系，所以只需要一个参数就可以完成字段的匹配。我们这里在销售数据里面把...
在可使用「多對多基數關聯性」之前,兩個資料表之間的關聯性是在 Power BI 中定義的。 關聯性中必須至少有一個資料表資料行包含唯一的值。 但是通常不會有任何資料行包含唯一的值。例如,兩個資料表可能有標示為 CountryRegion 的資料行。 不過,任一資料表中的 CountryRegion 值都不是唯一的。 若要聯結這類...
