This message is not necessarily an error but rather an informational message indicating the model selection outcome.
  Cause:
  
  Data Characteristics: The automatic model selection process evaluates historical data patterns. If the data shows a consistent upward or downward trend, the system will select the trend model.
  Seasonality: If the data does not exhibit strong seasonal patterns but shows a trend, the trend model is chosen.
  Model Selection Criteria: The selection is based on statistical criteria that assess the fit of various forecasting models to the historical data.
  
  Solution:
  
  Review Data: Check the historical data to understand why the trend model was selected. Look for patterns, trends, or seasonality in the data.
  Adjust Model Settings: If you believe that a different model (e.g., seasonal model) would be more appropriate, you can manually adjust the model settings in the forecasting profile.
  Data Preprocessing: Ensure that the data is clean and preprocessed correctly. Remove any outliers or anomalies that might affect the model selection.
  Consult Documentation: Refer to SAP documentation for more details on model selection criteria and how to interpret the results.
  Testing Different Models: If necessary, test different forecasting models manually to see if they yield better results for your specific data set.
  
  Related Information:
