Trend Curve
This supporting function is used to support entry and updates of trend curves.
Description
A trend curve is used to specify future trends, such as the upward or downward fluctuations in demand for an item. It indicates each forecast period’s percent change compared to demand during the first period of the year. Trend curves are used in connection with forecast simulation.
Trend curves are identified by a three-digit number and can be defined for each calendar year. This means that a trend curve ID specified for an item group cannot be changed from one year to another, even if the curve itself changes.
Trend curves can be connected to item groups in 'Item Group. Open' (CRS025).
