When drilling into a matrix report's summarization, the detail data visible is...

• A. All fields in the data source
• B. Fields you define in the Detail Data section that the user also has access to
• C. Only summary fields
• D. Calculated fields only

Answer: (B)

When you drill into a matrix report’s summarization, the detail data that appears is determined by what you configure as detail data and by the user’s access rights. In Workday reporting, the Detail Data section defines exactly which fields are available for drill-down from the summarized view, and those fields must be accessible to the user. This means the drilled-up data isn’t simply “everything in the data source,” and it isn’t limited to just summary fields or only calculated fields. Instead, it shows the specific fields you’ve chosen to expose in the Detail Data section that the user is permitted to view, giving you control over what detail information is revealed during drill-down.
