  The error occurs when:
  
  A custom handler class is defined without the required prefix ('Y' or 'Z').
  The system is trying to access or utilize a custom handler class that does not conform to the naming conventions.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Custom Handler Class:
  
  Check the configuration or code where the custom handler class is being referenced. This could be in a configuration setting, a custom program, or an enhancement.
  
  
  
  Rename the Class:
  
  If you have access to the ABAP development environment, rename the custom handler class to ensure it starts with 'Y' or 'Z'.
  For example, if the class is named MY_CUSTOM_HANDLER, rename it to Z_MY_CUSTOM_HANDLER or Y_MY_CUSTOM_HANDLER.
  
  
  
  Update References:
  
  After renaming the class, ensure that all references to this class in your code or configuration are updated to reflect the new name.
  
  
  
  Transport Changes:
  
  If you are working in a development environment, make sure to transport the changes to the appropriate systems (e.g., quality assurance, production) as needed.
  
  
  
  Test the Changes:
  
  After making the changes, test the functionality that was previously causing the error to ensure that it now works correctly.
