Trend Limitation 

Use

For forecast models that calculate forecast values for products with a trend, you can limit this trend by default. In Service Parts Planning (SPP) you can activate a trend limitation for the following trend forecast models:

·        Second-order exponential smoothing

·        Seasonal trend model

·        Linear regression model

You have the following possibilities to define the trend limit:

·        You can define the limit as a percentage increase or a percentage decrease. The forecast curve is then smooth after an increase of x %.

You can define the increase value on the SAP Easy Access menu under Advanced Planning and Optimization → Service Parts Planning → Planning → Forecast → Forecast Profile on the tab page General.

·        You can define the limit as a certain number of months. The forecast curve is then smooth after a defined length of time.

You can define this time in the forecast parameter Forecast Trend Limiter (time) on the tab page Model Parameter.

Prerequisites
