Filter Choice Controlling Other Filters

[colettb]

Hello Community!

I am developing a dashboard and have multiple filters.  What I am wanting to do is when the user makes a choice with one filter, the other filters will have their options modified.  

As an example, let's say I have 2 filters - Phase and Study.  The Phase filter has 3 choices - Early Phase, Ongoing and Post Market.  The Study filter has a list of clinical studies.

If the user chooses all options in teh Phase filter, all clinical studies will be listed in the Study filter.  What I want is that if the user chooses, for example, Early Phase in the Phase filter, I want only Early Phase studies to be listed in the Study filter.  

So basically I want the values chosen in one filter to control what is available to choose from in other filters.  

Thanks for any guidance you can give me!

Thank you everyone for your great suggestions!  I was able to resolve my issue.

Hi @colettb 

1. Ensure Proper Data ModelYou need to ensure that your data model contains both the tables are logically connected.
2. Create a relationship between Phase and Study (You can set cross filter direction between both the tables).

Hi @colettb  Since I don't have Visibility to your data model layout I would suggest a simple fix.

Select your Relationship in Data Model View and Set the Cross Filter Direction to Both bewteen the tables.

Thanks,

1. Ensure Proper Data Model Design
You need a structure where both Phase and Study belong to the same table, or they are properly related.
Alternatively, if you have dimension tables:
PhaseDim (PhaseID, PhaseName)
StudyDim (StudyID, StudyName, PhaseID)
Then ensure:
StudyDim[PhaseID] is related to PhaseDim[PhaseID]
Your fact table has StudyID, which connects to StudyDim[StudyID]

2. Add Slicers
Add a slicer for Phase
Add another slicer for Study
Power BI will automatically filter the Study slicer based on the selected Phase if the model relationships are correct.

3. Ensure Relationships Are Set to "Single" Direction
Go to Model View and ensure:
Relationships between Phase → Study are set to Single directional filtering (from Phase to Study or from Study to Fact).
Avoid bidirectional relationships unless absolutely needed.

4. Avoid Adding Filters from Unrelated Tables
If your slicers come from unrelated tables, cascading will not work. Make sure the filter field sources are properly related either directly or through a fact table.
