• What is the cause and solution for SAP error message /SAPAPO/ESPP_PR459 - Automatic model selection has selected linear regression + season ?

  The SAP error message /SAPAPO/ESPP_PR459 indicates that the automatic model selection process in SAP Advanced Planning and Optimization (APO) has chosen a linear regression model with seasonal components for forecasting. This message is not necessarily an error but rather an informational message indicating the model that has been selected for the forecasting process.
  Cause:
  
  Data Characteristics: The automatic model selection process analyzes historical data patterns. If the data shows a linear trend with seasonal fluctuations, the system will select a linear regression model with seasonal adjustments.
  Model Selection Criteria: The selection is based on statistical criteria such as the goodness of fit, error metrics, and the nature of the data (e.g., seasonality, trend).
  
  Solution:
  
  Review the Data: Check the historical data used for forecasting. Ensure that it is clean, complete, and accurately reflects the underlying trends and seasonality.
  Model Validation: Validate the selected model by reviewing the forecast accuracy metrics (e.g., MAPE, RMSE) to ensure that the model is appropriate for your data.
  Manual Model Selection: If you believe that a different model would be more appropriate, you can manually select a different forecasting model in the SAP APO system.
  Adjust Parameters: If necessary, adjust the parameters for the forecasting model to better fit your data. This may include changing the seasonal period or modifying the regression parameters.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on model selection and forecasting in APO.
  
  Related Information:
  
  Forecasting Models in SAP APO: Familiarize yourself with the different forecasting models available in SAP APO, including exponential smoothing, linear regression, and others.
  SAP Notes and Support: Check SAP Notes for any known issues or updates related to forecasting models and automatic model selection.
  Training and Resources: Consider training sessions or resources on SAP APO forecasting to better understand how to interpret model selection and improve forecasting accuracy.
  
  If you continue to experience issues or have specific concerns about the model selection process, it may be beneficial to consult with an SAP expert or your organization's SAP support team for further assistance.
