The Scenario and Version dimensions represent the broadest categories of data in your application. Scenario describes the type of data you are working with, such as actual, forecast, or budget.
Version contains the different budget stages or iterations that you use, providing snapshots of data during each phase of the budget preparation process. As such, the Version dimension describes the possible stages or outcomes within the context of a scenario. For example, one stage represents the initial budget and another stage represents the final budget. Version also contains revision members. Administrators create members for budget revisions
R(x) in the Revision parent member.
