How To Make a Drillthrough Page in Power BI

Drillthrough pages in Power BI allow users to dive deeper into their data with just a click, providing detailed insights while maintaining a clean and navigable main report. In this tutorial, Microsoft Certified Trainer Allison Gonzalez walks through creating and customizing drillthrough pages in Power BI, making reports more interactive and informative.

What Are Drillthrough Pages?

Drillthrough pages, sometimes referred to as detail pages, offer users a way to access specific, granular information linked to their report’s visuals. Instead of manually searching for data, users can right-click on a visual or hover over it to access the drillthrough functionality. This approach enhances presentations and ensures quick answers to deeper questions.

How to Set Up a Drillthrough Page

Follow these steps to create your own drillthrough page in Power BI:

1. Duplicate an Existing Page: If your new page resembles an existing one, save time by duplicating it. Right-click the page tab and select "Duplicate."
2. Add Drillthrough Fields: On the new page, drag the relevant data fields into the “Drillthrough” area at the bottom of the visualization pane. For example, if focusing on profit details, drag the profit measure to this area.
3. Customize Visuals: Add visuals like tables, charts, and slicers that display the desired data insights. For instance, you might include a table of products and a bar chart showing profit by month.
4. Create a Back Button: Power BI automatically adds a back button to drillthrough pages. You can also customize this by linking a logo or image to act as the back button using the action feature in the formatting pane.
5. Hide the Page: To prevent users from directly accessing the drillthrough page, hide it by selecting the crossed-eye icon in the page view menu. This ensures users only access it via drillthrough actions.

Enhancing User Experience

Allison shares tips for creating seamless and visually appealing drillthrough pages:

• Use clear, descriptive page names to guide users.
• Design layouts that highlight relevant details, such as tables for granular data or charts for trends.
• Incorporate slicers or filters for additional interactivity on the drillthrough page.
• Customize buttons to align with your branding and user expectations, like making logos act as navigational elements.

Practical Applications

Drillthrough pages are especially useful in scenarios where detailed data analysis is essential, such as exploring regional sales performance or product-specific metrics. By adding this functionality, you empower report users to get answers quickly without overwhelming the main dashboard with excessive details.

Conclusion

Drillthrough pages are a powerful feature in Power BI, enabling users to balance high-level reporting with deep data exploration. With Allison’s step-by-step guidance, anyone can create intuitive and interactive drillthrough pages to enhance their reports.
