• What is the cause and solution for SAP error message /SAPAPO/ESPP_PR452 - Automatic linear model selection has chosen linear regression ?

  The SAP error message /SAPAPO/ESPP_PR452 indicates that the automatic linear model selection process in SAP Advanced Planning and Optimization (APO) has defaulted to using linear regression for the forecasting model. This typically occurs when the system determines that the data does not meet the criteria for more complex models or when there is insufficient data to support them.
  
  Cause:
  
  Data Characteristics: The data may not exhibit the necessary patterns (like seasonality or trends) that would allow for the selection of more complex forecasting models.
  Insufficient Data: There may not be enough historical data points for the system to identify a more sophisticated model.
  Model Configuration: The settings in the forecasting model configuration may not be optimized for the data being analyzed.
  Data Quality Issues: Missing values, outliers, or inconsistencies in the data can lead to the selection of a simpler model.
  
  
  Solution:
  
  Review Data Quality: Ensure that the historical data is clean, complete, and free of outliers.
