DM: "TooFew" Parameter not working as Intended.
Summary:
Context: As per the paper mentioned in article :
White Paper: Demand management forecasting Parameters:KB10068
TooFew is defined as : Specifies the minimum amount of data for which the time series will be
considered forecast feasible. Cannot equal zero.
The note also says:The Forecasting Methods cannot work properly with less than 2 data points, therefore it is best to set this
parameter to a value higher than 2 data points (2 or above in Daily Forecasting aggregation, 14 or above to
Weekly Forecasting aggregation, 62 or above to a Monthly Forecasting aggregation).
Issue: Since the business forecasts in monthly buckets, I set the parameter to 62→ what happened was every combination got forecasted as the highest level and the method used was "N" Naive.
