Mathematical Forecast with Seasonal Influence

Use mathematical forecast with seasonal influence when calculating forecasts for items with variances according to different seasons, i.e. different types of clothing.

The seasonal influence is based on a seasonal curve for the current item group or product group, or a calculated seasonal index based on the alpha or gamma factor entered.

It is possible to enter a manual value or an adjustment on each period. Enter a period in 'Automatic Forecast. Open' (FCS001) and do your adjustments, it is possible to enter a manual forecast at 'Manual Forecast/MDS. Open' (FCS350) as well. The manual entered value will override the calculated value.

Before you start

In order to use mathematical forecast with seasonal influence, these conditions must be fulfilled:

  • In 'Forecast Method. Open' (FCS300), set Seasonal infl to 1.
  • In 'Seasonal Curve. Open' (CRS915), define a curve for each year you are going to use it.
  • In 'Item Group. Open' (CRS025), specify the seasonal curve to use for each item group.
  • In 'Item. Open' (MMS001), specify the Item group for each item to be included in the forecast calculations.
