Which expansion shows every Member under a specified parent Member?

The answer is based on the definition and function of the "Descendants" term within the context of a Chart of Accounts structure in OneStream. "Descendants" refers to all members that are under a specified parent member in the hierarchy, including children, grandchildren, and so forth, extending to all levels of related members beneath that parent.

When you perform a "Descendants" expansion, you would see not just immediate children, but every single linked member all the way down the tree. This allows users to understand the full scope of relationships and categories that fall under that parent member, which is essential for various reporting and aggregation tasks in financial software like OneStream.

Other options may have relevant functions in terms of viewing or interacting with the hierarchy, but they do not extend the view to all lower levels as comprehensively as "Descendants" does. For instance, "Children" would only show the immediate next level down from the specified parent, while "Hierarchy" might refer more generally to the structure without the specific intent to show all members under a parent. "Sub-entities" typically refers to divisions or operational units that further illustrate organizational structure but do not capture the full breadth of all members in the same way as "Descendants."
