Blank Option In slicer in power bi

I have designed a report to select categories and products, but a blank option is appearing in the slicer even though there is no blank value in the database.

Hey @Sarany03 ,

The blank option showing up in your Power BI slicer even when your data source doesn't contain any blank CategoryName values can happen due to a few common reasons. 

Possible Causes for (Blank) in Slicers

  1. Unrelated Table Joins (Many-to-One Issue)

  2. Missing or Null Foreign Keys in Fact Table

  3. Inactive Relationships

  4. Calculated Tables or DAX Measures

 

Option 1: Check and Fix Relationships

Go to Model view:

  • Ensure that the relationship between Products and Category is active and one-to-many from Category[CategoryID] to Products[CategoryID].

  • Check for any ambiguous relationships that might confuse slicer context.

Option 2: Filter Out Blanks

If you're using a slicer visual directly from the field (e.g., Category[CategoryName]), apply a visual-level filter to exclude blanks:

  1. Select the slicer.

  2. Go to the Filters pane.

  3. Drag CategoryName into the Filters on this visual section.

  4. Set filter condition to is not blank.

Option 3: Create a Filtered Column (DAX)

If blank values are being pulled from a relationship mismatch, use a calculated column or measure like:

CategoryNameFiltered = IF(ISBLANK('Category'[CategoryName]), "Not Assigned", 'Category'[CategoryName])

Then use CategoryNameFiltered in the slicer.

Option 4: Use a DISTINCT() DAX Table

If you're using a DAX-generated slicer table like:

CategorySlicerTable = DISTINCT('Products'[CategoryName])

Make sure there are no blank entries in 'Products'[CategoryName].

Use a Matrix or Table to Inspect Data

  • Add a table visual showing Category[CategoryName] and COUNTROWS(Products) to see if some categories have no matching rows (which can cause blank entries too).

Hi,
The answer above really covers all the main reasons why a (Blank) option might show up in your slicer, even if your table has no blanks. One extra thing you can quickly check is if you have any inactive relationships or hidden tables that might be accidentally connected to your slicer. Sometimes, these can sneak in and create unexpected blanks.

Also, after making changes to relationships or filters, remember to refresh your data model and test the slicer again.

Hope this helps you get rid of that (Blank) value for good!
