Basic Concept of Versions
When using planning models in SAP Analytics Cloud, versions are used to organize, compare, and maintain actual, plan, and forecast data.
You only need one version for historical (actual) data. But when planning for the future, organizations can create many plan iterations for various reasons.
These plans could each use a different version of the data. When working with versions, you can change data in one version without impacting the data in other versions.
Version Management lets you manage different versions and types of plans. For example, your organization can create a new version for each new forecast period. You can separate your forecasts from other types of plans like budgets and strategic plans.
Version is a dimension in a planning model. When planning models are created, the actual version is provided as a system default. Additional versions are created while planning in stories.
