Weird Slicer Behaviour

[Nozama]

I have this kind of a structure and I am trying to have all the categories on a single slicer such that they cascade. I am faced with a confounding issue.

1. When I select (say) Planet 1 and Planet 2 on the slicer (multiple select allowed), one of my visuals updates the data. That is fine.
2. However, now when I select Solar System 1AS (which has only Planet 1 and Planet 2) the visual updates to include everything else on the data model too. I am expecting it to never update or show anything different from when I select Planet 1 and Planet 2 together.

Hi @Nozama 

What you're describing sounds like a classic issue with filter propagation in the data model — particularly when relationships between hierarchy levels (e.g., Planet → Solar System → Galaxy → Universe) are not properly configured or behave unexpectedly.

Here are a few troubleshooting steps to consider:

1. Check your relationships: Make sure all relationships are single-directional (from top to bottom of the hierarchy), and that there are no many-to-many relationships unless absolutely necessary.

2. Validate your slicer structure: If your slicer uses a flattened hierarchy or a disconnected table, it's possible that selecting a higher-level item (like a Solar System) inadvertently expands the filter context beyond the expected boundaries.

3. Test using a simplified measure: Create a temporary measure using ISFILTERED() or SELECTEDVALUE() to detect whether your visuals behave differently based on what's being selected in the slicer.

To provide more targeted help, please share a sample PBIX file that replicates your model structure — with only the relevant columns and no sensitive data — via any public cloud storage (e.g., OneDrive, Google drive...).
