This error indicates that there is an attempt to create or register a Global Data Type (GDT) with a code that already exists in the system.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that you are trying to create a new Global Data Type (GDT) with a code that is already in use. Each GDT must have a unique identifier, and if you attempt to create one with a code that already exists, the system will throw this error.

  Development Environment Conflicts: In a development environment, if multiple developers are working on the same project, one might create a GDT with a code that another developer has already used.
  
  Solution:
  
  Check Existing GDTs: Before creating a new GDT, check the existing GDTs in the system to ensure that the code you want to use is not already taken. You can do this by navigating to the relevant section in the SAP system where GDTs are managed.
  Use a Unique Code: If the code is already in use, choose a different, unique code for your new GDT.
  Review Data Migration Scripts: If this error arises during data migration, review your migration scripts or data files to ensure that they do not contain duplicate entries for GDT codes.
  Collaboration and Communication: If you are in a team environment, communicate with your team members to avoid conflicts in GDT creation.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Global Data Types and their management to understand the constraints and best practices.
