  Review Master Data:
  
  Check the master data (e.g., product master, location master) to ensure that there are no inconsistencies that could affect the planning horizon.
  Validate that all relevant data is correctly maintained and that there are no missing or erroneous entries.
  
  
  
  Consult SAP Notes:
