  Cause:
  
  Missing Class Definition: The class specified in the error message (&1) does not exist in the system. This could be due to a missing configuration or an incomplete implementation.
  Incorrect Configuration: The system might be configured to use a class that has not been properly set up or has been deleted.
  Transport Issues: If the class was recently transported from another system, the transport might not have included all necessary objects.
  Authorization Issues: The user may not have the necessary authorizations to access the class.
  
  Solution:
  
  
  Check Class Existence:
  
  Use transaction code SE24 (Class Builder) to check if the class exists in the system. If it does not exist, you may need to create it or transport it from another system.
