  Solution:
  
  
  Assign a PPM Number:
  
  Navigate to the relevant transaction where the error occurred.

  Check Configuration:
  
  Review the configuration settings in the APO system to ensure that they are set up correctly for the use of PPMs.
  Consult with your SAP Basis or APO configuration team if you suspect there are issues with the configuration.
