Smart SAP Assistant

• What is the cause and solution for SAP error message XT631 - Changes only permitted in domain controller system ?

  The SAP error message XT631, which states "Changes only permitted in domain controller system," typically occurs in a system landscape where you have a Central User Administration (CUA) or a domain controller setup. This error indicates that you are trying to make changes to user data or configuration in a system that is not designated as the domain controller.
  Cause:
  
  Domain Controller Setup: In a CUA environment, there is a designated domain controller system that manages user data and authorizations. Changes to user data should only be made in this domain controller.
  Attempting Changes in a Child System: If you are logged into a child system (a system that is part of the CUA landscape but not the domain controller) and attempt to make changes to user data, you will encounter this error.
  
  Solution:
  
  Identify the Domain Controller: Determine which system in your landscape is the domain controller. This is typically the system where user administration is centralized.
  Make Changes in the Domain Controller: Log into the domain controller system and perform the necessary changes there. This includes creating, modifying, or deleting user accounts and roles.
  Synchronize Changes: After making changes in the domain controller, ensure that the changes are synchronized with the child systems. This is usually handled automatically by the CUA setup, but you may need to check the synchronization status.
  User Administration Transactions: Use the appropriate transactions for user administration, such as SU01 (User Maintenance) or SU10 (Mass User Maintenance), in the domain controller.
  
  Related Information:
  
  Central User Administration (CUA): CUA allows for centralized management of users across multiple SAP systems. It simplifies user administration by allowing changes to be made in one place.
  User Synchronization: Changes made in the domain controller are propagated to the child systems. Ensure that the synchronization settings are correctly configured.
  Authorization Issues: Ensure that you have the necessary authorizations to make changes in the domain controller. If you lack the required permissions, you may need to contact your SAP security administrator.
  
  Additional Considerations:
  
  Documentation: Refer to SAP documentation on CUA and user administration for detailed procedures and best practices.
  System Landscape: Be aware of your system landscape and the role of each system to avoid confusion when making changes.
