多对多基数关系
The many-to-many cardinality relationships have been available since Analysis Services 2019. However, the relationship editor in Visual Studio does not provide the ability to change the filter direction. The default is “Both”, which is seldom the appropriate choice. The filter direction can be modified in Power BI Desktop.

One of our customers (Jürgen Faßbender, Orbit Gmbh) wanted to use Visual Studio to control this setting, but he was not able to do so: “We opened a support ticket as you suggested, but Microsoft closed the issue without delivering a fix. The workaround provided is editing the model.bim manually, or use a different editor like Tabular Editor."

多对多基数关系自 Analysis Services 2019 起就可用。但是，Visual Studio 中的关系编辑器不提供更改筛选器方向的功能。默认为“Both”，这很少是合适的选择。可以在 Power BI Desktop 中修改筛选器方向。

我们的一位客户（Jürgen Faßbender，Orbit Gmbh）想要使用 Visual Studio 来控制此设置，但他无法这样做：“我们按照您的建议打开了ticket，但 Microsoft 关闭了该问题，但没有提供修复程序。提供的解决方法是手动编辑 model.bim，或使用不同的编辑器，如表格编辑器。“
