When using Demand Forecasting and Engineering Versions, history is lost when changing Engineering Versions. A function should be added to copy historical demand from the same item with an old version to the new version. Engineering Versions are treated as an inventory dimension when creating the Item allocation keys, so the forecast is only generated for that specific Version. When adding a new Version of the same item, the data for that item is lost and the new Version starts from scratch.

This functionality is necessary for Versions, but could also be useful to seed data on new items that will have similar usage/forecasting. Using the Data Management Entity to load Historical demand works as a work around, but requires exporting, formatting, and uploading data. This is inefficient and time consuming when dealing with Version changes.
