  Close Existing Sessions: If you have multiple sessions open with the same name, consider closing one or more of them to resolve the conflict.
  Check for Open Sessions: You can check your currently open sessions by using the transaction code /nSM04 (User Overview) to see if there are any sessions that you can close.
