• What is the cause and solution for SAP error message SHMA054 - Global class &1 already existed with original in &2 ?

  The SAP error message SHMA054 indicates that there is a conflict with a global class that you are trying to create or modify. Specifically, it means that a global class with the same name already exists in the system, and it is associated with a different original object.
  Cause:
  
  Duplicate Class Name: The most common cause of this error is that you are attempting to create a new global class with a name that already exists in the SAP system.
  Transport Issues: If you are working in a transport environment, it is possible that the class was transported from another system, leading to conflicts.
  Namespace Conflicts: If you are using a custom namespace, there may be conflicts with standard SAP classes or other custom classes.
  
  Solution:
  
  Check Existing Classes: Use transaction SE80 or SE11 to check if a class with the same name already exists. If it does, you may need to rename your new class or modify the existing one.
  Use a Unique Name: Ensure that the name of the new global class is unique and does not conflict with existing classes.
  Transport Management: If the issue is related to transport, ensure that all transports are correctly imported and that there are no inconsistencies in the transport directory.
  Namespace Management: If you are working in a custom namespace, ensure that you are following the naming conventions and that there are no conflicts with standard SAP objects.
  Check for Active Versions: If the existing class is active, you may need to deactivate it or create a new version of the class if you have the necessary authorizations.
