What you need

Before you begin using DAX in Power BI Report Builder, make sure you have the following:

  • A Power BI shared dataset
  • Power BI Report Builder installed on your computer
  • Familiarity with DAX syntax and functions

Connect to the Power BI semantic model

The first step in using DAX in Power BI Report Builder is connecting to the Power BI semantic model. This allows you to access and analyze the data from your shared dataset. To connect to the Power BI semantic model, follow these steps:

  1. Open Power BI Report Builder
  2. Click on the Data Sources tab
  3. Select Power BI from the list of available data sources
  4. Enter the necessary connection details, such as the server URL and authentication credentials
  5. Click Connect to establish the connection

Once you're connected to the Power BI semantic model, you can start using DAX in your paginated reports.

Get the DAX query for the dataset

To create a paginated report based on a Power BI shared dataset, you'll need to retrieve the DAX query for the dataset. The DAX query defines the data that will be displayed in your report. To get the DAX query, follow these steps:

  1. Open Power BI Desktop
  2. Open the shared dataset you want to create a report from
  3. Click on the Modeling tab
  4. Select Existing Connections from the Get Data group
  5. Choose the shared dataset from the list
  6. Click on the Report Builder button to generate the DAX query
  7. Copy the generated DAX query

Once you have the DAX query, you can use it to create the dataset in Power BI Report Builder.

Create the dataset with the query

Now that you have the DAX query for your shared dataset, you can create the dataset in Power BI Report Builder. To create the dataset, follow these steps:

  1. Open Power BI Report Builder
  2. Click on the Data Sources tab
  3. Select Power BI from the list of available data sources
  4. Paste the DAX query into the Query field
  5. Click on the Refresh Fields button to retrieve the dataset schema
  6. Click OK to create the dataset

With the dataset created, you can now start designing your paginated report.

Create a table in the report

Once you have the dataset in Power BI Report Builder, you can create a table to display the data. To create a table, follow these steps:

  1. Drag and drop the Table control from the toolbox onto the report canvas
  2. Select the dataset you created from the Data tab
  3. Drag and drop the desired fields from the dataset onto the table
  4. Customize the table layout and formatting as needed

By using DAX in the dataset, you can apply powerful calculations and filters to the table to enhance its functionality and insights.

Format the report

Formatting your paginated report is an important step to make it visually appealing and easy to read. Power BI Report Builder offers various formatting options to customize your report's appearance. Some of the formatting options include:

  • Changing font styles, sizes, and colors
  • Applying conditional formatting based on data values
  • Adding headers, footers, and page numbers
  • Setting page size and orientation
  • Adjusting margins and padding

Take advantage of these formatting options to create a professional-looking report that effectively presents your data.

Considerations and limitations

While using DAX in Power BI Report Builder offers numerous benefits, there are some considerations and limitations to keep in mind:

  • DAX calculations and expressions can impact report performance, especially with large datasets
  • Complex DAX formulas may require advanced knowledge and expertise
  • Power BI Report Builder has certain limitations compared to Power BI Desktop
  • Ensure your DAX query and calculations are accurate to avoid incorrect report results
