• What is the cause and solution for SAP error message 0T115 - Cannot delete system &1 due to transport routes ?

  The SAP error message 0T115 indicates that you cannot delete a system due to existing transport routes that are dependent on that system. This typically occurs when you attempt to delete a system from the Transport Management System (TMS) configuration, but there are transport routes that still reference that system.
  
  Cause:
  The primary cause of this error is that the system you are trying to delete is part of a transport route configuration. Transport routes define how transport requests are moved between different systems in the landscape (e.g., Development, Quality Assurance, Production). If there are active routes that include the system you want to delete, SAP will prevent the deletion to maintain the integrity of the transport landscape.
  
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Check Transport Routes:
  
  Go to the TMS configuration (Transaction code: STMS).
  Navigate to the Transport Routes section.
  Review the transport routes to identify any routes that include the system
