What aspect of delivery considerations pertains to allowing users to drill down or roll up data within a report?

The aspect of delivery considerations that allows users to drill down or roll up data within a report is interactive delivery. This type of delivery enables users to engage with the data dynamically, allowing them to explore various levels of detail based on their interests or requirements. When a report is presented in an interactive format, users can click on summary values to view more detailed data (drill down) or collapse detailed views to see higher-level summaries (roll up). This interactivity enhances user experience and enables more meaningful analysis of the data.

Other types of delivery, such as static delivery, do not offer this level of user engagement. Static delivery presents fixed reports without the flexibility to interact with the data, thereby limiting users' ability to explore different perspectives. Scheduled delivery refers more to the timing of report availability rather than user interactivity. Filtering may allow users to focus on specific subsets of data but does not inherently provide the drill-down or roll-up capabilities that characterize interactive delivery.
