• What is the cause and solution for SAP error message CTS_CONFIG_MSG_CL105 - Cluster &1 cannot be changed; it belongs to a foreign domain (&2) ?

  The SAP error message CTS_CONFIG_MSG_CL105 indicates that you are trying to change a transport cluster that belongs to a different domain than the one you are currently working in. This typically occurs in the context of the Change and Transport System (CTS) in SAP, which manages the transport of changes across different systems.
  Cause:
  
  Domain Mismatch: The transport cluster you are trying to modify is associated with a different domain than the one you are currently in. Each transport domain is a logical grouping of systems that share transport routes and configurations.
  Configuration Issues: There may be misconfigurations in the transport domain settings, leading to attempts to modify clusters that are not part of the current domain.
  
  Solution:
  
  
  Check Transport Domain Configuration:
  
  Use transaction STMS to access the Transport Management System.
  Verify the transport domain configuration and ensure that you are working within the correct domain.
  Check the transport routes and clusters to confirm their associations.
  
  
  
  Use the Correct Domain:
  
  If you need to make changes to a transport cluster that belongs to a different domain, you must switch to that domain or perform the changes in the appropriate system that is part of that domain.
  
  
  
  Consult with Basis Team:
  
  If you are unsure about the domain configuration or need to make changes that require administrative access, consult with your SAP Basis team. They can provide insights into the transport domain setup and assist with any necessary changes.
  
  
  
  Review Transport Layer Settings:
  
  Ensure that the transport layer settings are correctly configured for the systems involved. This includes checking the transport routes and ensuring that they are correctly defined.
  
  
  
  Related Information:
  
  Transport Domain: A transport domain is a logical grouping of SAP systems that share transport routes and configurations. Each domain has its own transport directory and configuration.
  Transaction STMS: This transaction is used to manage the transport system in SAP, including configuring transport routes, domains, and clusters.
  Transport Routes: These define how transports are moved between systems in the domain. Ensure that the routes are correctly set up to avoid issues with transport requests.
  
  If the issue persists after checking the above points, further investigation into the transport configuration and logs may be necessary to identify any underlying issues.
