How to Create a Custom Slicer in Power BI for Enhanced Table Sorting

paginated reports


Are you looking to improve your Power BI reports with advanced sorting techniques? Look no further! In this guide, I’ll walk you through creating a custom slicer in Power BI. This tool will enable you to sort your tables in ascending or descending order with ease, making your reports more dynamic and user-friendly.

Why Custom Slicers?

Sorting tables in Power BI is straightforward but might not be obvious for all users, especially those new to the platform. A custom slicer with clear sorting options enhances the user experience by making this functionality more accessible.

 Custom Slicer in Power BI

Designing the Slicer Interface:


To create an intuitive and easy-to-use slicer that lets users choose sorting options for your table.


  • 1. Create a New Table:
    • In Power BI, go to the ‘Modeling’ tab and click ‘New Table’.
    • Define the table with two rows, one for each sorting option (ascending and descending).

For example:

Sort Order =
    “Label”, STRING,
    “Value”, STRING,
        {“Ascending”, “asc”},
        {“Descending”, “desc”}


    • This creates a table named ‘Sort Order’ with labels and values for sorting.
  • 2. Add Visual Icons or Text:
      • Use Unicode characters or emojis for ascending (↑) and descending (↓) alongside the text labels for clarity.
  • 3. Create a Slicer Visualization:
    • Drag the ‘Sort Order’ table onto your report canvas.
    • Convert it into a slicer visualization.
    • Customize the slicer’s appearance to match your report’s style.

Leveraging the RankX Function:


To use the ‘RankX’ function for dynamically adjusting the table’s sorting based on the slicer selection.


  • 1. Create a Measure:
    • Go to the table where you want to apply the sorting.
    • Create a new measure (e.g., “Dynamic Rank”) using the ‘RankX’ function.

Example Measure:

Dynamic Rank =
    MAX(‘Sort Order'[Value]),


    • Here, TableName[CategoryColumn] is the column you are sorting, and TableName[ValueColumn] is the column determining the sort order (e.g., sales amount).
  • 2. Incorporate Slicer Selection:
    • The MAX(‘Sort Order'[Value]) part dynamically changes the ranking order based on the slicer selection.

Slicer and Table Integration:


To integrate the slicer with your data table, ensuring it controls the table’s sorting order.



  • 1. Apply the ‘Dynamic Rank’ Measure:
      • Add the ‘Dynamic Rank’ measure to your table visualization.
      • Set the table to sort based on this measure.
  • 2. Ensure Interaction:
    • Ensure that the slicer and table are interacting correctly in the ‘Format’ settings. The slicer selection should change the sorting order of the table.

Adding Flexibility: Sorting Across Multiple Measures:


To enable sorting by various measures like sales, unit price, or quantity using the ‘Switch’ function.


  • Enhance the ‘Dynamic Rank’ Measure:
  • Modify the ‘Dynamic Rank’ measure to include a ‘Switch’ statement that changes the sorting column based on another slicer’s selection.

Example Enhanced Measure:

Dynamic Rank =
VAR SelectedMeasure = SELECTEDVALUE(MeasuresTable[MeasureName], “DefaultMeasure”)
        “Sales”, SUM(TableName[Sales]),
        “Unit Price”, AVERAGE(TableName[UnitPrice]),
        “Quantity”, SUM(TableName[Quantity]),
    MAX(‘Sort Order'[Value]),


Here, MeasuresTable[MeasureName] is another slicer that allows users to select which measure (e.g., sales, unit price) to sort by.


Implementing Custom Slicer Real-World Scenarios:

Now that you have successfully created a custom slicer in Power BI, it’s crucial to understand how to apply it effectively in various business contexts. Let’s explore some real-world scenarios where this slicer can significantly enhance data analysis and presentation:

  • Sales Performance Analysis:
      • Apply the slicer to sales data tables to quickly identify top-performing products or regions. For instance, sorting by sales figures in ascending or descending order can highlight bestsellers or areas needing improvement.
  • Financial Reporting:
      • In financial reports, use the slicer to sort expense categories or revenue streams. This helps in quickly pinpointing the largest expenses or the most profitable revenue sources.
  • Inventory Management:
      • For inventory data, the slicer can be used to sort items based on stock levels, helping to easily identify items that need restocking or are overstocked.
  • Customer Feedback Analysis:
      • In customer feedback or survey data, sort responses by various metrics like satisfaction scores or response times to gain insights into customer satisfaction and operational efficiency.
  • HR and Employee Data:
    • Human Resources can leverage the slicer to sort employee data, such as performance ratings or tenure, aiding in effective personnel management and decision-making.


The addition of a custom slicer in your Power BI reports is more than a mere enhancement; it’s a transformation. By following this guide, you have equipped your reports with a tool that not only sorts data efficiently but also significantly elevates the user experience. This slicer adds a level of interactivity and sophistication to your reports, making data analysis more intuitive and insightful.
