statistical forecasting


I am running a statistical forecast on a group of materials using a composite forecast. The selection I am using contains Material (numerous) - Sales Division (one div) - Sales Organization (one sales org). It appears that running in the foreground or directly out of the data view is creating the stat forecast at the group level and disaggregating down to the materials. This is exactly what I want it to do.

I then run this same selection in the background with an aggregation level of Material - Sales Division - Sales Org. It appears when running it this way that it is calculating the Stat forecast for each Material rather than as a group.

When I do the same background run but only at the Sales Division - Sales Org level I am not really sure what is going on. When I look at the spool the MAPE that is calculated is the same regardless of what the selection is that I am using.

Does anybody know what is actually happening behind the scenes when running the stat in these three different ways?
