In OneStream, a hierarchy shows relationships between which elements?

• A. Cubes
• B. Members
• C. Dimensions
• D. Instances

Answer: (B)

Hierarchies in OneStream define how members in a dimension relate to each other in a parent-child structure. This tree of members establishes drill-down and roll-up relationships, letting you navigate and aggregate data at different levels. The focus is on the members themselves—the items inside a dimension—so a hierarchy shows how those members connect. Cubes are the data containers that use dimensions; they aren’t what the hierarchy maps. Dimensions are the containers of members, but the hierarchy doesn’t map relationships between entire dimensions. Instances are separate deployment configurations and don’t define the internal member relationships. So the relationships shown by a hierarchy are among the members within a dimension.
