RE: SYS Warehouse in Forecasting

Good question!
Nothing comes immediately to mind - obviously there's something different
about the way forecasting is running the calculations... there's gotta be
something different in the forecast controls. Double check EVERYTHING and I'll
bet you'll find something different, somewhere. You might also look at the
data and compare, month-by-month SYS versus the one warehouse. Look at the
other warehouses, too, to make sure you didn't get some data loaded in the
wrong place accidentally.
Good luck

Thank you, Dave, this helps. But I have a follow up question:
If an item only exists in one selling warehouse, why would the forecast in
SYS and that 1 warehouse be significantly different?
Thanks again,

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 other 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.
