或者在Power Query Editor处理了Merge或者Append数据后,Power BI也会自动生成关系。 例如DAX分享24: Power BI中得到最新的数据 - 知乎 (zhihu.com)中使用了Merge,如果没有勾掉自动生成关联关系automatic relationship。 查看Manage Relationships中数据表之间的关系,可以看到Power BI报表中自动生成了CustomerCurrent和Custome...
解释一下:默认情况下,当Power BI加载数据后,会自动检查加载的数据表之间是否有相同的名字的字段,会自动建立相应的关系; 或者在Power Query Editor处理了Merge或者Append数据后,Power BI也会自动生成关系。 例如DAX分享24: Power BI中得到最新的数据中使用了Merge,如果没有勾掉自动生成关联关系automatic relationship。

N/AData isn't being pushed into Power BI.Push data to semantic modelsThis section describes how to create and push data into the three primary types of real-time semantic models that you can use in real-time streaming.You can push data into a semantic model by using the following methods...
Other factors are at play that increase file size and decrease the number of rows Power BI can export. If the visualization uses data from more than one data table, and no active relationship exists for those tables in the data model, Power BI only exports data for the first table. The ...
We have a massive Power BI Desktop update this month. Composite models, which allow you combine direct query and import sources together in one model, is now generally available. Two of the top feature requests on UserVoice, expand/collapse on the matrix and copy and pasting visuals between De...
s challenging for Power BI to determine which values to use in the relationship. For example, suppose you have a table of customers and a table of purchases. A customer can make multiple purchases, and a purchase can have multiple customers. In this case, a many-to-many relationship exists...
在 Power BI 支持多对多关系之前,关系涉及的列至少有一个必须包含唯一值。 不过,在某些场景下可能没有列包含唯一值,比如分析订单和产品的时候,一个订单包含多个产品,一个产品也可以属于多笔订单,通常的解决方法是在模型中引入包含必要唯一值的附加表,也称做桥接表。现在借助多对多关系,你可以直接连接此类表,关于...
We don't recommend you relate many-to-many dimension-type tables directly. This design approach requires configuring a relationship with a many-to-many cardinality. Conceptually it can be achieved, yet it implies that the related columns will contain duplicate values. It's a well-accepted design...
So, we recommend that you activate bi-directional filtering in a measure definition by using the CROSSFILTER DAX function instead. The CROSSFILTER function can be used to modify filter directions—or even disable the relationship—during the evaluation of an expression....
