Hi,
Below are the definitions for the factors .
Alpha factor
The system uses the alpha factor to smooth the basic value. If you do not specify an alpha factor, the system will automatically use the alpha factor set in the profile. In the standard SAP profile, this is the factor 0.2.
Beta factor
The system uses the beta factor to smooth the trend value. If you do not specify a beta factor, the system will automatically use the beta factor set in the profile. In the standard SAP profile, this is the factor 0.1.
Gamma factor
The system uses the gamma factor to smooth the seasonal index. If you do not specify a gamma factor, the system will automatically use the gamma factor set in the profile. In the standard SAP profile, this is the factor 0.3.
Delta factor
The system uses the delta factor 0.3 in every forecast model to smooth the mean absolute deviation.
Please try check the forecasting profile/model.
