  Review Master Data:
  
  Ensure that all necessary master data is complete and correctly maintained. Check product master data, location data, and any other relevant master data.
  
  
  
  Check Configuration:
  
  Review the configuration settings in the APO system to ensure they are set up correctly. This includes checking the planning area settings and the integration with other SAP modules.
  
  
  
  Transport Check:
