To configure drill-through navigation, start by creating a destination page that will display detailed information. This page should contain visuals and data relevant to the drill-through context. For example, if your main report shows sales by region, your drill-through page might show individual transactions for a selected region.
On the destination page, locate the Visualizations pane and find the Drill-through section. Drag the field you want to use as the drill-through filter into this area. Common choices include categories like Product Name, Customer ID, or Region. When you add a field here, Power BI automatically creates a back button on the page, allowing users to return to their original view.
You can configure multiple drill-through fields to create more flexible navigation paths. The 'Keep all filters' option determines whether existing report filters carry over to the drill-through page, maintaining the analytical context.
To use drill-through, users right-click on a data point in any visual on the source page and select 'Drill through' from the context menu, then choose the appropriate destination page. The destination page then filters to show only data related to the selected item.
Cross-report drill-through extends this functionality across different Power BI reports, enabling navigation between separate files while passing filter context. Enable this by selecting 'Cross-report' in the drill-through settings.
Best practices include clearly naming drill-through pages, using consistent field names across reports, and designing destination pages with relevant detailed visuals that complement the summary views users navigate from.
Configure Drill-Through Navigation in Power BI
Why Drill-Through Navigation is Important
Drill-through navigation is a critical feature in Power BI that enables users to navigate from a summary report to a detailed page containing specific contextual information. This functionality allows report consumers to explore data at a granular level while maintaining the context of their analysis. For data analysts, understanding drill-through is essential because it creates interactive, user-friendly reports that facilitate deeper insights.
What is Drill-Through Navigation?
Drill-through is a Power BI feature that allows users to right-click on a data point in one report page and navigate to another page that shows detailed information filtered by the selected context. For example, clicking on a specific product category in a sales summary could take users to a detailed page showing all transactions for that category.
Key components of drill-through include: - Source Page: The page where users initiate the drill-through action - Target Page: The destination page containing detailed information - Drill-through Filters: Fields added to the drill-through well that determine what context is passed
How Drill-Through Works
1. Create a target page - Design a detail page with the visuals you want to display
2. Add drill-through filters - In the Visualizations pane, locate the Drill-through section and drag fields into it. These fields define what context will filter the target page
3. Configure cross-report drill-through - Enable this option if you want drill-through to work across different reports in the same workspace
4. Keep all filters - Toggle this option to preserve or exclude other filters when drilling through
5. Add a back button - Power BI automatically adds a back button, but you can customize or reposition it
Configuration Options
- Keep all filters: When enabled, all existing filters from the source page transfer to the target page - Cross-report drill-through: Allows drill-through between separate Power BI reports - Back button: Provides navigation back to the originating page - Multiple drill-through fields: You can add several fields to create specific filtering combinations
Exam Tips: Answering Questions on Configure Drill-Through Navigation
1. Remember the drill-through well location: Questions often test whether you know that drill-through filters are configured in the Visualizations pane under the Drill-through section on the target page, not the source page
2. Understand cross-report drill-through requirements: Both reports must be in the same workspace, and the feature must be enabled in the target report settings
3. Know the difference between drill-through and drill-down: Drill-down explores hierarchical data within the same visual, while drill-through navigates to a different page with filtered context
4. Back button behavior: The back button is automatically created when you add a drill-through field. Expect questions about its default behavior and customization
5. Filter context: Understand that only the fields in the drill-through well pass their filter context to the target page unless 'Keep all filters' is enabled
6. Scenario-based questions: When given a scenario asking how to show details for a specific item clicked by users, drill-through is typically the correct answer rather than bookmarks or page navigation
7. Publishing requirements: For cross-report drill-through to function, both reports must be published to the Power BI service
8. Practice identifying when drill-through is appropriate: It is best used when users need to see detailed transactional data or supporting information for aggregated values shown in summary visuals
