• What is the cause and solution for SAP error message SCTS_DIST_CTL_LNDSCP020 - Central CTS configuration only possible on domain controller ?

  The SAP error message SCTS_DIST_CTL_LNDSCP020 indicates that a central Change and Transport System (CTS) configuration is being attempted on a non-domain controller system. In a distributed SAP landscape, the central CTS configuration must be performed on the domain controller, which is the system that manages the transport routes and configurations for the entire landscape.
  Cause:
  The error occurs because:
  
  You are trying to configure the central CTS on a system that is not designated as the domain controller.
  The system does not have the necessary authorizations or settings to perform central CTS configuration.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Identify the Domain Controller:
  
  Determine which system in your landscape is the domain controller. This is typically the system that was set up first and is responsible for managing transport routes.
  
  
  
  Perform Configuration on Domain Controller:
  
  Log in to the domain controller system.
  Execute the central CTS configuration steps on this system instead of the non-domain controller.
  
  
  
  Check Transport Configuration:
  
  Ensure that the transport configuration is correctly set up on the domain controller. You can check this in transaction STMS (Transport Management System).
  Verify that the transport routes and landscape configuration are correctly defined.
  
  
  
  Authorization Check:
  
  Ensure that you have the necessary authorizations to perform the configuration on the domain controller. You may need to consult with your SAP Basis administrator if you encounter authorization issues.
