• What is the cause and solution for SAP error message /SAPAPO/MC01HEUR001 - Resource &1 is not classified ?

  The SAP error message /SAPAPO/MC01HEUR001 Resource &1 is not classified typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a resource that is being referenced in a heuristic or planning run is not properly classified. This can prevent the heuristic from executing correctly.
  Cause:
  
  Resource Classification Missing: The resource in question has not been assigned to a classification system or does not have the necessary characteristics defined.
  Incorrect Configuration: The resource may not be configured correctly in the system, leading to it being unrecognized by the heuristic.
  Master Data Issues: There may be issues with the master data related to the resource, such as missing or incomplete entries.
  
  Solution:
  
  
  Check Resource Classification:
  
  Go to the resource master data in SAP APO.
  Ensure that the resource is classified correctly. You can do this by checking the classification view and ensuring that the necessary characteristics are assigned.
  
  
  
  Assign Resource to a Class:
  
  If the resource is not classified, you need to assign it to a class. This can be done in the classification system (transaction CL02 or CL03).
  Create or modify the class to include the resource and assign the necessary characteristics.
  
  
  
  Review Heuristic Settings:
  
  Check the settings of the heuristic you are trying to run. Ensure that it is configured to recognize the resource and that it is included in the planning run.
  
  
  
  Master Data Maintenance:
  
  Review the master data for the resource to ensure that all required fields are filled out correctly.
  If necessary, update the resource master data to include any missing information.
  
  
  
  Testing:
  
  After making the necessary changes, run the heuristic again to see if the error persists.
