What functionality does "drillthrough" provide in Power BI reports?

Drillthrough functionality in Power BI reports enhances user interactivity by enabling users to navigate from one report page to another while preserving detailed context about the data. This feature allows users to select data points on the current page and then access a dedicated drillthrough page that provides deeper insights relevant to their selection. For example, if a user clicks on a specific region in a sales report, the drillthrough page can show more granular information about sales transactions for that particular region, such as product details and customer information, thereby enriching the analysis.

This capability is particularly useful for data exploration, as it facilitates a seamless transition between summary views and detailed insights, making it easier for users to analyze data deeply without losing context. Users can enhance their reports by creating dedicated drillthrough pages tailored to specific dimensions or metrics, which can be designed to provide additional relevant information based on selections made in the main report.

Other choices do not accurately represent the purpose of drillthrough in Power BI. For instance, the option suggesting that it allows users to view high-level summaries only does not capture the essence of drillthrough functionality, which is designed to provide detailed views rather than summaries. Similarly, restricting user access to sensitive data is related to security features rather than navigation features in reports, and
