A 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.
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 plan iterations for a variety of reasons. These plans can 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
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.
