It is typically used for monitoring key metrics and is often created by pinning visuals from different reports.<\/p><p><span style=\"color: #000000;\"><strong>Q6: How is Power BI Report different from a Dashboard?<\/strong><\/span><br \/>A Power BI report is a multi-page document that contains interactive data visualizations.

A well-defined data model helps users build reports that are easy to analyze and update.

For example, sales managers may only have access to data from their own region, while directors can view data for all regions.<\/li><li><strong>Role Assignments<\/strong>: In Power BI Service, administrators can assign roles to users within workspaces, granting different levels of access (e.g., viewer, contributor, administrator).<\/li><\/ul><p><span style=\"color: #000000;\"><strong>Q16: What are row-level security (RLS) features in Power BI?<\/strong><\/span><br \/>Row-Level Security (RLS) restricts data visibility based on user roles.
