 Is it possible to have created multiple active relationships in Power BI  ?

No, it's not possible to have multiple active relationships between two tables in Power BI. Each table can only have one active relationship with another table, represented by a solid line in the Power BI Desktop data model. However, there are several solutions and workarounds to achieve similar functionality depending on your specific needs:

1. One Active Relationship and Inactive Ones:

  • You can have one active relationship for the primary data flow you need, and keep other potential relationships inactive (represented by dotted lines). These inactive relationships can still be used in specific calculations through the USERELATIONSHIP function in DAX, allowing you to conditionally switch between different data sources based on your needs.

2. Merge Tables:

  • If the two tables contain closely related data and you primarily need their combined information, consider merging them into a single table before establishing relationships. This simplifies the model and eliminates the need for multiple relationships.

3. Create Separate Views:

  • If you need distinct perspectives on the data based on different relationships, create separate views with different active relationships for each analysis. This provides focused reports tailored to specific insights.

4. Utilize Calculated Columns:

  • For specific scenarios where you want to combine data from two tables without an active relationship, utilize calculated columns in DAX to integrate relevant data points into your existing table. This can be helpful for specific calculations or visualizations.

5. Third-Party Tools:

  • Explore some third-party tools and custom connectors that might offer advanced functionality for handling multiple active relationships or implementing specialized data connections.

While multiple active relationships aren't directly supported in Power BI, these alternative approaches and workarounds can help you achieve similar results and create flexible and insightful data models.

Remember to choose the method that best suits your specific data structure, analysis needs, and technical expertise.
