What must be enabled if component worksheets drill to detail?

For component worksheets to successfully drill to detail, it is essential that the composite worksheet also has the capability to drill to detail. This relationship is critical because the drilling functionality relies on the overall structure of the composite worksheet being conducive to such actions. If the composite worksheet is not set up to allow drilling, then the individual component worksheets cannot follow suit, regardless of their individual settings.

When the composite worksheet is enabled for drilling, it allows users to click through from a higher-level summary or aggregated data in the composite view down into the detailed data in the component worksheets. This ensures a consistent user experience and enhances the usability of the data system, enabling users to analyze data more deeply across different levels of granularity.

The other options do not correlate directly with the requirement for enabling drill-down functionality. For instance, stating that drilling is not permissible would contradict the foundational purpose of the worksheets. Additionally, while editing permissions can influence some functionalities, they do not directly impact the ability to drill into details. Lastly, visibility of all components is beneficial but is not a prerequisite for enabling drill-down capability. Hence, the correct understanding points to the necessity for the composite worksheet to also support drilling for the action to take place effectively across its components.
