Explanation

Scenario: The customer service department requires a visual that can be filtered by both sales month and ship month independently. In Power BI Desktop, only one relationship can be active between a Fact table and Dimension table, so we need an extra table. Use one-to-many relationship to be able to filter. Add a one-to-many relationship from both the Date tables to Sales table. https://docs.microsoft.com/en-us/power-bi/guidance/relationships-active-inactive https://docs.microsoft.com/en-us/power-bi/transform-model/desktop-relationships-understand
