This error indicates that the smoothing values you are trying to set for a forecasting model are outside the acceptable range of 0 to 1.
  Cause:
  
  Invalid Input Values: The smoothing values you have entered for the forecasting model are either negative or greater than one.
  Configuration Issues: There may be a misconfiguration in the forecasting settings or parameters that leads to invalid values being used.
  Data Entry Errors: Manual entry of values may have led to incorrect data being inputted.
  
  Solution:
  
  
  Check Input Values: Review the smoothing values you have entered. Ensure that they are within the range of 0 (inclusive) to 1 (inclusive). For example, a value of 0.5 is valid, while -0.1 or 1.2 would trigger this error.
  
  
  Adjust Forecasting Parameters: If you are using a forecasting model that allows for the adjustment of smoothing parameters, ensure that these parameters are set correctly. You may need to consult the documentation or guidelines for the specific forecasting method you are using.

  Consult Documentation: Refer to SAP documentation or help resources for the specific forecasting model you are using. This can provide insights into acceptable values and configurations.
  
  
  Testing: After making adjustments, test the forecasting process again to ensure that the error has been resolved.
