Question: The predictive analytics documentation asks for the name of a Cube View to run the models against. What does that Cube View need include?

• Each row in the Cube View becomes an item to forecast in predictive analytics.
  • Be cautious with the number of rows in the Cube View
  • It is possible to nest dimensions in the Cube View, but predictive analytics is not intended to be run across thousands of rows at once.
• The Cube View needs include base intersections as predictive analytics can’t write to any parent intersection.
• Columns are typically going to show time dimension members. You will need to include the reference period but do not need to show all history in the Cube View. 
• Currently, predictive analytics projects data to the same time frequency (i.e.,  monthly to monthly).
