Question

How can I create a dynamic date range filter that automatically adjusts based on user-selected slicer values?
Your Power BI report requires a dynamic date range filter that automatically updates based on user interactions with slicers. What is the best way to implement this functionality using DAX or Power Query? How can you ensure that the date range dynamically reflects the selected slicer values?

Answer 1

To create a dynamic date range filter in Power BI that adjusts based on user-selected slicer values, use DAX measures or Power Query transformations.

1. Using DAX Measures (Recommended for Flexibility)

You can create a measure that dynamically filters the data based on the selected slicer values.

Step 1: Create a Measure for Min and Max Date Selection

SelectedStartDate = MIN( 'Date'[Date] )  
SelectedEndDate = MAX( 'Date'[Date] )  

Step 2: Apply the Dynamic Date Filter in a Measure

FilteredSales =  
CALCULATE(  
    SUM('Sales'[Amount]),  
    FILTER(  
        'Sales',  
        'Sales'[Date] >= [SelectedStartDate] && 'Sales'[Date] <= [SelectedEndDate]  
    )  
)

This ensures that sales data dynamically updates based on the selected slicer range.

2. Using Power Query (For Pre-Filtering Data Before Load)

If you want to limit the dataset before loading into Power BI:

• Use Relative Date Filters in Power Query (e.g., last 12 months).
• Create parameter-based filtering to allow users to define a custom date range before data import.
