Re: SYS Warehouse in Forecasting

[Dave Turbide <dave@xxxxxxxxxxxxxxx>]

I believe Forecasting does separate forecasts for each warehouse and for
the SYS warehouse using the sum of the data from the other warehouses. In
othe words, the SYS forecast is not the sum of the warehouse forecasts, it
is a separate forecast made from the sums of the data. Theoretically, the
SYS forecast will be more stable and probably more accurate because of the
larger sample size.
