Hello,
I have ran into a Power BI issue that I have not seen before in a slicer visual that says "You are using fields that don't have a supported set of relationships."
For context, I am working in a report that brings a table into my model via Storage Mode: DirectQuery and I have an existing relationship between that table and another table in my model via Storage Mode: Import as a Many to One relationship that is active. In my slicer, I am trying to bring a hierarchy from the Direct Query table in the field (which works fine) plus a field from my Import table. However, this is when I receive the error when trying to bring in each piece into the slicer.
What's interesting is that I can bring both pieces into any other type of visual, like a matrix for example, and I do not get an error and it seems to work. The slicer is the issue.
What could be causing this issue that exists just for the slicer visual?
Hi @Anonymous ,
The error message “You are using fields that don’t have a supported set of relationships” in Power BI usually occurs when you are trying to create a relationship between two tables that don’t have a common field or when you are trying to use fields that don’t have a supported set of relationships.
You can try to check this by looking at the Troubleshooting on relationships:

The issue you're encountering with the slicer in Power BI when trying to combine fields from tables in different storage modes (DirectQuery and Import) is a common challenge due to the limitations and behaviors specific to slicers versus other visual types.
Here are the main factors and steps to consider resolving this issue:
1. Different Data Storage Modes:
Power BI has specific behaviors when dealing with DirectQuery and Import modes, especially around how data is retrieved and managed. Slicers, unlike other visuals, often require a more direct interaction with the data model, which can lead to issues if the underlying data relationships and model configurations aren't fully compatible.
2. Supported Relationships:Although you have a relationship set up between your DirectQuery table and Import table, slicers might be more sensitive to the type of relationships and how they are configured. Slicers specifically may not support certain complex scenarios that other visuals can handle, particularly when it involves crossing between DirectQuery and Import modes.
3.Model Relationship Review:Double-check your model’s relationships. Ensure that the relationship is not only active but also appropriate in its configuration:
- Verify that the relationship cardinality (Many to One, One to Many, etc.) is correctly set.
- Check if the relationship is set to both 'Single' direction and 'Both' directions, and try adjusting this setting to see if it resolves the slicer issue.
- Consider the filter direction in the relationship to ensure it supports the intended data flow.
4. Using a Bridging Table:
If the slicer continues to throw errors, consider creating a bridging or intermediary table that consolidates necessary attributes from both tables into a single table in a compatible storage mode (preferably Import if the dataset size allows). This table would then be used exclusively in the slicer, avoiding cross-mode data referencing.
5. Composite Model Adjustments:
Power BI's Composite models can allow you to combine DirectQuery and Import tables efficiently, but they have nuances:
- Ensure your model is set up to handle composite scenarios effectively. This setup might involve aligning granularity or ensuring index fields are present in both tables to support the relationship.
6. Slicer Configuration:
Try simplifying the slicer by using fewer fields or adjusting its properties. Sometimes, simplifying the interaction level (e.g., reducing hierarchy levels or selecting single instead of multiple data fields) can bypass issues arising from complex data interactions.
7. Testing Alternative Visuals:
If the slicer simply cannot handle the cross-mode fields despite all adjustments, you might consider using another type of filter mechanism, such as a filter pane or a custom visual that can offer similar functionality without the same limitations.
To further investigate, you could also look into the latest Power BI updates or patches, as sometimes specific bugs related to visual interactions are resolved in these updates.
Implementing these strategies should help address the slicer issue or at least offer a workaround that maintains the integrity of your report's analytical capabilities.
