How does the new short-term forecasting creation method work?

The new Creation Method > Import Forecast feature in Workforce Management allows forecasters to import an actual forecast up to 6 weeks long that was created outside of workforce management.  This feature can also be used to import a forecast created in Workforce management that was exported and then edited in an external tool like excel. This is not a historical data import. The time zone for the file needs to be in UTC time zone. Please note that all data in the file should fall within the Forecast Duration date range displayed in the Add Short-Term Forecast screen. If the time zone is specified then there should only be one row of data for each Interval Start Date and Planning Group. If not, there should only be one row of data for each Interval Start UTC Date and Planning Group. If you need to import historical data in order to build a forecast you should use the Weighted Historical Index with Source Data Import creation method which allows for up to 8 weeks of historical data but can only generate a one week forecast at a time.
