Ready to unleash the full potential of your Power BI implementation? You're in the right place. We've gathered 11 top-notch best practices to take your Power BI game to the next level. Let's dive in and supercharge your data-driven journey:
- Less Visual Noise, More Impact: Ever wondered what’s slowing down your report performance? Often, it’s an overcrowded dashboard. To keep things snappy, limit visuals to a maximum of eight widgets per report page. Ensure each page doesn’t exceed 30 points. (Cards: 1, Gauges: 2, Charts: 3, Maps: 3, Grids: 5). And for dashboards, stick to a maximum of 10 tiles.
- Tame Unnecessary Interactions: By default, all visuals in your report can chat with each other. It’s like a party that can get out of hand. To enhance performance, control and modify visual interactions. This not only streamlines your reports but also reduces backend queries.
- Enable Row-Level Security (RLS): Keep your data on lockdown. Power BI only imports data authorized for the user. RLS restricts access based on user characteristics. The secret to substantial performance gains? Combine Power BI roles with backend roles and rigorously test them before rolling them out.
- Certified Custom Visuals: Stick to Microsoft AppSource-certified custom visuals. These visuals have been through the gauntlet and proven to have robust, high-performing code. Plus, they’re the only ones that can be viewed in “Export to PowerPoint” and email subscriptions.
- Ditch Hierarchical Filters: Is your Power BI sluggish with hierarchical filters? Swap them out for multiple filters. This simple change can significantly enhance performance.
- Categorize Your Data: Give your data a label. Sort it into High Business Impact (HBI), Medium Business Impact (MBI), and Low Business Impact (LBI) categories. This makes sharing and access management crystal clear.
- Embrace On-Premises Data Gateway: Opt for the on-premises data gateway over the Personal Gateway. It’s more efficient, especially when dealing with larger databases.
- Divide and Conquer with Gateways: Using the same gateway for both Scheduled Data Refresh and Live Connection can slow down Live Connection performance. Create separate gateways for each to maintain a smooth user experience.
- Test Custom Visuals: Be cautious with non-certified custom visuals. Especially with large datasets or complex aggregations, they might not perform as expected. If one’s a slowpoke, switch to an alternative visual to keep your report loading swiftly.
- Keep It Simple: Complicated measures and aggregations can put a damper on performance. Whenever possible, push calculated columns and measures closer to the data source. If you’re using a star schema, opt for calculated measures over calculated columns.
- Import What’s Essential: Why bring in the whole dataset when you can keep things trim and agile by importing only necessary fields? Power BI thrives on columnar indexes, making lean and narrow your best friends.
