  Cause:

  Analyzing the historical data to understand the context of the outliers.

  Data Correction: If the outliers are due to data entry errors, correct the underlying data in the system.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling outliers in your version of SAP APO.
