Outlier Correction An outlier is an historical value that lies outside a range that is expected. Outliers can falsify the forecast results. This function enables you to correct the outliers.
It is not possible to use outlier correction with the median forecast method (method 36).
Note
SAP has made considerable changes to the algorithms for outlier correction in Release SCM 4.1.
In this method the system uses the ex-post forecast to determine a tolerance lane. If a historical value lies outside this tolerance lane, the system views it as an outlier and corrects it.
