How can a user filter a report without modifying the actual report?

Filtering a report without modifying the actual underlying report can be achieved through the Power BI Service. In the Service, users have the capability to interact with reports more dynamically, allowing them to apply filters based specifically on their own needs without altering the original report design or data model. This is crucial for maintaining the integrity of the report while still providing the flexibility for users to gain insights tailored to their specific queries.

The other choices imply actions that would involve changing the report structure or the data presented within it. For instance, editing report level filters or adjusting visual level filters would directly modify how the report is constructed, impacting all users accessing that report. Creating new calculated columns would involve altering the data model, which is a more permanent modification. Therefore, utilizing the Power BI Service for filtering ensures that individual needs are met while preserving the original framework of the report for all other users.
