Anaplan Polaris is in Early Access at the moment. This means there are a number of known issues and some missing functionality. Some functionality that is available in the Classic Anaplan Calculation Engine will not initially be available when Polaris becomes GA. 

The attached PDF contains the latest available information on which features are expected to be delivered during the EA process and which features are not expected to be available when Polaris becomes Generally Available. This is subject to change without notice by Anaplan Product Management.
