If no group-level reconciliation modifiers have been specified, a bottom-up approach will be used to reconcile the forecasts. The procedure operates as follows.
First, Forecast Pro prepares forecasts for all groups and items.
Then, Forecast Pro recomputes the group-level forecasts by aggregating the constituent forecast (bottom up). The original group level forecasts are replaced, but their confidence limits are retained and proportionately adjusted.
Three group-level modifiers can be used to specify alternative reconciliation approaches or leverage group data structure. These modifiers can only be used on group-level data.
