  The SAP error message 5A658 indicates that a substructure with the specified name already exists in the ABAP Dictionary. This error typically occurs when you are trying to create or modify a structure or table in the ABAP Dictionary, and the name you are using for the substructure is already in use.
  Cause:
  
  Duplicate Name: The most common cause is that you are attempting to create a substructure with a name that is already used by another structure or table in the ABAP Dictionary.
  Namespace Conflicts: If you are working in a development environment where multiple developers are creating objects, there may be a naming conflict.
  Transport Issues: Sometimes, if objects are transported between systems, there may be inconsistencies that lead to this error.
  
  Solution:
  
  
  Check Existing Structures: 
  
  Use transaction code SE11 (Data Dictionary) to check if the substructure name already exists. You can search for the name in the "Structures" section.
  If it exists, consider using a different name for your new substructure.
  
  
  
  Rename the Substructure: If you find that the name is already in use, you can rename your substructure to something unique.
  
  
  Namespace Management: 
  
  Ensure that you are following the naming conventions and namespace rules in your development environment to avoid conflicts.
  If you are working in a shared environment, coordinate with your team to avoid naming collisions.
  
  
  
  Transport Requests: If you suspect that the issue is related to transport requests, check the transport logs and ensure that all objects are correctly transported and activated in the target system.
  
  
  Check for Active Objects: Sometimes, an object may be active in the system but not visible in the dictionary. Use transaction SE80 to check for any active objects that might be causing the conflict.
