• What is the cause and solution for SAP error message CMS161 - Location &3 is passed more than once in path from &1 to &2 ?

  The SAP error message CMS161 indicates that a location (in this case, a specific node or object in a system path) has been referenced more than once in a path from one point to another. This typically occurs in the context of system configurations, such as in the SAP Change Management System (CMS) or when dealing with transport routes.
  Cause:
  The error is caused by a circular reference or duplication in the path definition. This can happen if:
  
  A location is incorrectly configured in the transport route.
  There are multiple entries for the same location in the path.
  The system is trying to resolve a path that leads back to a previously visited location, creating a loop.
  
  Solution:
  To resolve the CMS161 error, you can follow these steps:
  
  
  Check the Transport Route Configuration:
  
  Go to the transaction code STMS (Transport Management System).
  Navigate to the transport routes and check the configuration for the specific path from &1 to &2.
  Ensure that each location is only listed once in the path.
  
  
  
  Review the Path Definition:
  
  Identify the path that is causing the issue and review its definition.
  Look for any duplicate entries or circular references.
  
  
  
  Modify the Path:
  
  If you find a duplicate location, remove the extra entry.
  If there is a circular reference, adjust the path to eliminate the loop.
  
  
  
  Test the Configuration:
  
  After making changes, test the transport route to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration, refer to SAP documentation or consult with your SAP Basis team for best practices in setting up transport routes.
