• What is the cause and solution for SAP error message APOC_OC_CONFIG153 - Callback must be publicly instantiatable. ?

  The SAP error message APOC_OC_CONFIG153 indicates that there is an issue with a callback class in the context of the SAP APO (Advanced Planning and Optimization) system. Specifically, the error message states that the callback must be publicly instantiatable, which means that the class in question is not accessible for instantiation due to its visibility settings.
  Cause:
  
  Visibility Modifier: The callback class is likely defined with a visibility modifier that restricts its instantiation. For example, if the class is defined as private or protected, it cannot be instantiated outside of its defining context.
  Incorrect Configuration: The configuration settings for the callback may not be set up correctly, leading to the system being unable to instantiate the required class.
  Missing Implementation: The callback class may not be implemented correctly or may be missing entirely.
  
  Solution:
  
  Check Class Definition: Review the definition of the callback class in the ABAP code. Ensure that it is declared as public so that it can be instantiated by the system.
  CLASS your_callback_class DEFINITION
    PUBLIC
    ...
  ENDCLASS.
  
  Review Configuration: Check the configuration settings in the APO system where the callback is being used. Ensure that the correct class is referenced and that all necessary parameters are set.
  Implement Missing Methods: If the callback class is defined but lacks the necessary methods or implementations, ensure that all required methods are implemented correctly.
  Transport Requests: If changes were made in a development environment, ensure that they are properly transported to the production environment.
  Consult Documentation: Refer to SAP documentation or notes related to the specific APO functionality you are working with to ensure that you are following best practices.
