Which Dimension has both base-level and parent-level member data?

• A. Entity
• B. Time
• C. Account
• D. Scenario

Answer: (A)

In OneStream, dimensions can hold hierarchical members where some are the actual, lowest-level (base) members and others are higher-level (parent) members used for rollups and alternative views. The Entity dimension is designed to model the organizational structure, so it naturally accommodates both: you have base-level members for each legal entity and parent-level members that group multiple entities for consolidated reporting or broader views. For example, base-level entities might be Subsidiary A and Subsidiary B, while a parent-level member could be a Group that consolidates those subsidiaries, or a Global entity that sums across groups. This dual capability is what makes the Entity dimension the one that has both base-level and parent-level member data. Time, Account, and Scenario are used for other purposes (tracking periods, financial accounts, and planning scenarios) and do not inherently require or support this combination in the same way.
