  • Protect sensitive data: Consider row-level security (RLS) or data masking for sensitive content.

5. Customize User Experience:

  • Filters and slicers: Control which data users see by embedding filters and slicers with the report.

  • Navigation and interactivity: Enable specific navigation features and interactivity options as needed.

  • Theme and branding: Customize the report's appearance to match your application's branding.

6. Manage Refresh and Updates:

  • Set refresh schedule: Ensure data stays up-to-date by setting a refresh schedule in the Power BI service.

  • Manage versions: Track report changes and updates within the Power BI service.

Additional Considerations:

  • License requirements: Embedded reports typically require Power BI Pro or Premium licenses for users viewing them.

  • Performance optimization: Consider caching and performance tuning techniques for large datasets or high usage scenarios.
