  Adjust Planning Parameters:
  
  If the production versions are valid and necessary, you may need to adjust the planning parameters or settings in the planning area to ensure that the system can handle multiple production versions appropriately.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for specific guidelines on managing production versions in APO.
