If using a manual forecast it is possible to enter the values in another way than entering the forecast line by line. One way is to enter a yearly demand and distribute it with a distribution curve. This can be done by F14=Dist F/C in 'Manual Forecast/MDS. Open' (FCS350). You enter a distribution curve, yearly demand, start period and a number of periods to distribute. The yearly demand from 'Item. Connect Warehouse' (MMS002) is proposed, if available.
If you have used the forecast for a number of years, the statistics could be fetched to your forecast by pressing F15=Rtr history in 'Manual Forecast/MDS. Open' (FCS350) or in a batch run using 'Manual Forecast. Update fr Last Year His' (FCS480).
