What is the purpose of drill-down actions in Power BI?

Drill-down actions in Power BI are designed to allow users to explore data at a more granular level. When utilizing the drill-down feature, you can take a broad overview of your data represented by aggregates, such as totals or averages, and then "drill down" to see the underlying details that contribute to those aggregates. For example, if you have sales data aggregated by year, using drill-down could allow you to view the data by quarter or month, revealing more specific insights and trends that are not visible at the aggregate level.

This capability enhances data analysis by enabling users to investigate and discover patterns, anomalies, or insights that may require further exploration. By drilling down, users achieve a more nuanced understanding of their data, which can support better decision-making and allow for more effective data storytelling.

In contrast, the options that involve viewing only aggregated data, analyzing from a higher perspective, or exporting to other formats do not encompass the key functionality of drill-down actions, which specifically emphasize the examination of data in greater detail.
