  The SAP error message MDG_OIF205 indicates that a structure name you are trying to create or modify in the Master Data Governance (MDG) system is already in use. This typically occurs when you attempt to define a new structure with a name that is already assigned to an existing structure in the system.
  Cause:
  
  Duplicate Structure Name: The most common cause is that the structure name you are trying to use is already defined in the system.
  Namespace Conflicts: If you are working in a custom namespace, there might be conflicts with standard SAP structures or other custom structures.
  Development Environment: If you are in a development environment, it’s possible that another developer has already created a structure with the same name.
  
  Solution:
  
  
  Check Existing Structures: 
  
  Use transaction code SE11 (Data Dictionary) to search for the structure name you are trying to use. This will help you confirm if the structure already exists.

  Use a Unique Naming Convention: 
  
  Establish a naming convention for your structures to avoid conflicts. This could include prefixes or suffixes that are unique to your development team or project.
  
  
  
  Consult Documentation: 
  
  Review any documentation or guidelines provided by your organization regarding naming conventions and structure definitions.
  
  
  
  Check Transport Requests: 
  
  If you are working in a transport environment, ensure that the structure is not part of an untransported request that might be causing conflicts.
