  The SAP error message 0T302 indicates that there are no active transport route configurations in the specified system. This error typically arises when you attempt to perform a transport operation (like releasing a transport request) and the system cannot find a valid transport route to follow.
  Cause:
  
  Missing Transport Routes: The transport routes may not be defined or activated in the Transport Management System (TMS).
  Incorrect Configuration: The transport domain may not be properly configured, or the transport routes may not be assigned correctly.

  Check Transport Routes:
  
  Go to the TMS configuration by executing transaction code STMS.
  In the Transport Management System, navigate to Transport Routes.
