- Data Size and Handling Limitations:Power BI has a 1 GB limit per dataset when using the Power BI Pro license. For larger datasets, you either need to use Power BI Premium or utilize Direct Query, which can sometimes affect performance.Handling very large datasets can also result in slower performance, especially during data refresh or complex calculations.
- Row-Level Security for Large Models:Power BI's row-level security (RLS) can become complex to manage in large models with intricate role definitions. While it allows for controlling access to data based on user roles, managing and testing multiple security roles can be challenging as the model scales.
- Limited Customization of Visuals:Power BI provides a wide range of default visualizations, but some advanced users might find its customization options restrictive compared to other tools like Tableau. Although Power BI allows for custom visuals, creating or importing them can require additional work or third-party tools.
- Complex DAX Functions:The learning curve for Data Analysis Expressions (DAX) can be steep, especially when creating complex calculations or time intelligence functions. Writing and optimizing advanced DAX formulas for large datasets can be difficult for beginners or users unfamiliar with the syntax.
- Refresh Rate Limitations:Power BI Pro only supports 8 data refreshes per day, which might not be sufficient for businesses that need real-time or near-real-time reporting. To increase this limit (up to 48 refreshes per day), users must upgrade to a Power BI Premium license, which can be expensive.
