Which of the following is an example of a Reverse Member Expansion?

Reverse Member Expansion refers to the ability to access or retrieve members in a hierarchy by tracing backwards up to their parent nodes, typically used in the context of organizational structures or financial consolidations.

TreeDescendantsR stands out as the appropriate choice for Reverse Member Expansion because it allows for navigating the hierarchy in reverse, effectively retrieving parent nodes from any given child node. This functionality is fundamental when trying to analyze data from a bottom-up perspective, where understanding parent-child relationships within the hierarchy is crucial for accurate reporting and analysis.

In contrast, other choices like NodeExpand focus on expanding the child members from a specific node, which is a forward traversal technique. BackwardReference may refer to a mechanism in dimensional frameworks that isn't necessarily about the traversal of a hierarchy but more about referring back to an entity. ParentExpand similarly indicates a function that primarily expands to show child nodes rather than tracing back, and therefore does not align with the definition of Reverse Member Expansion.
