• What is the cause and solution for SAP error message 0T122 - Changes only permitted in domain controller system ?

  The SAP error message 0T122: Changes only permitted in domain controller system typically occurs in a system landscape where you have a central system (domain controller) and one or more satellite systems. This error indicates that you are trying to make changes in a system that is not designated as the domain controller for the relevant configuration or data.
  Cause:
  
  System Landscape Configuration: In a distributed SAP environment, certain changes (like customizing settings, user authorizations, etc.) are only allowed in the domain controller system. Satellite systems are meant to receive these changes but cannot initiate them.
  Authorization Issues: The user may not have the necessary authorizations to make changes in the current system.
  Incorrect System Role: The system you are working in is not configured as the domain controller for the specific data or configuration you are trying to change.
  
  Solution:
  
  Identify the Domain Controller: Determine which system is the domain controller for the specific configuration or data you are trying to change. This is usually the central system in your landscape.
  Make Changes in the Domain Controller: Log into the domain controller system and make the necessary changes there. After making the changes, they can be distributed to the satellite systems.
  Check Authorizations: Ensure that the user has the necessary authorizations to make changes in the domain controller system.
  Transport Requests: If applicable, use transport requests to move changes from the domain controller to the satellite systems.
  
  Related Information:
  
  System Landscape: Understanding the architecture of your SAP landscape (e.g., Development, Quality Assurance, Production) is crucial. Changes should typically be made in the Development system and transported to Quality Assurance and Production.
  SAP Notes: Check SAP Notes for any specific guidance or updates related to this error message. SAP frequently updates its documentation and provides solutions for common issues.
  Documentation: Review SAP documentation regarding system roles and landscape management to ensure proper configuration and understanding of where changes can be made.
