Each model has two default versions: Actual and Forecast. For example, you can use versions to compare actual and forecast sales data in your model.
You can also choose a current version in your model. The version set as Current displays by default when you open a model, and is the default version for line item formulas that use Versions as a dimension.
You can also merge actual data with forecast data to create a rolling forecast and set up variance reports.
Create and manage versions in Versions
in the model settings bar.Note: You can only set one version as the current or actual version in your model. You also cannot delete the actual version.
