Power Bi - Edit Parameters

Hi Johnbl , Thank you for reaching out to the Microsoft Community Forum.

Please try this:

1. Go to Modeling -> New Parameter -> What If Parameter. Set the Data Type to Whole Number (or Decimal if needed). Define the minimum and maximum range with the step size. Click OK
2. Power BI will create a new table with values in the specified range and a slicer to allow users to select values. You will also get a measure like Parameter Value which holds the selected value from the slicer.
3. Instead of using Slider_PQ directly in your Power Query, you can use the What-If Parameter measure in your DAX calculations. Create a new calculated column in your table using DAX.
4. Add the slicer created by the What-If Parameter to your report. This slicer will allow end users to dynamically change the parameter value, and your visuals will update accordingly.
5. Also please refer this document:
