• What is the cause and solution for SAP error message DEMO007 - Class '&' already exists ?

  The SAP error message DEMO007 indicates that a class with the specified name already exists in the system. This error typically occurs when you attempt to create a new class in the ABAP Workbench (SE80 or SE24) with a name that is already in use.
  Cause:
  
  Duplicate Class Name: The most common cause is that you are trying to create a class with a name that has already been defined in the system.
  Namespace Issues: If you are working in a specific namespace, ensure that the class name does not conflict with existing classes in that namespace or in the global namespace.
  Transport Requests: If you are working in a development environment, there may be transport requests that have not yet been imported into the system, which could lead to conflicts.
  
  Solution:
  
  
  Check Existing Classes: 
  
  Use transaction SE80 or SE24 to search for the class name you are trying to create. If it exists, you may need to choose a different name for your new class.
  You can also use transaction SE11 to search for the class in the Object Navigator.
  
  
  
  Rename Your Class: If you find that the class already exists, consider renaming your new class to something unique.
  
  
  Review Transport Requests: If you suspect that the class might exist in a transport request that has not been imported, check with your Basis team to see if there are pending transports that might contain the class definition.
  
  
  Namespace Considerations: If you are working in a custom namespace, ensure that you are following the naming conventions and that your class name does not conflict with existing classes in the same namespace.
  
  
  Check for Deletion: If you believe the class should not exist, check if it was deleted in a previous transport. You may need to restore it or create a new class with a different name.
