What is row-level filtering at source vs report level?

< 1 min read

Row-level filtering at source means restricting data directly in the database or query.
For example, SQL view returned only South region sales for regional managers.
Power BI never receives other region records, improving security and performance.
We used parameterized stored procedures for department-wise extraction.
Report-level filtering means data is fully loaded but filtered inside Power BI visuals.
Users can still potentially access hidden data if permissions are misconfigured.
We used report filters for date range and product category analysis.
Source filtering reduces dataset size and refresh time significantly.
Report filters are flexible but only for presentation, not strict security.
So source filtering is for security + performance, report filtering is for analysis convenience.
