  After defining the class type, you need to assign it to source category 4.
  This can typically be done in the same configuration area or through a related transaction.
  
  
  
  Check for Existing Class Types:
  
  If a class type already exists, ensure that it is correctly assigned to the relevant source category and that all necessary attributes are defined.
