• What is the cause and solution for SAP error message E2E_TESTING027 - ON: Buffer trace already activated by &1 (trace user: &2) ?

  The SAP error message E2E_TESTING027 indicates that a buffer trace is already activated for a specific user in the system. This message typically arises in the context of performance analysis or debugging, particularly when using the End-to-End (E2E) tracing functionality in SAP.
  Cause:
  The error occurs when a user attempts to activate a buffer trace while one is already active for that user. This can happen if:
  
  The user has previously activated a buffer trace and has not deactivated it.
  Another session or transaction initiated by the same user has already activated the trace.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Deactivate the Existing Trace:
  
  If you have access to the transaction where the trace was activated, you can deactivate it. This is typically done using transaction ST01 (System Trace) or ST05 (SQL Trace).
  In the trace tool, look for the option to deactivate the trace for the user in question.
  
  
  
  Check Active Traces:
  
  Use transaction ST01 or ST05 to check if there are any active traces for the user. If you find an active trace, you can deactivate it from there.
  
  
  
  Log Off and Log Back In:
  
  Sometimes, simply logging off and logging back into the SAP system can clear any lingering traces associated with the user session.
  
  
  
  Contact System Administrator:
  
  If you are unable to deactivate the trace or if the issue persists, it may be necessary to contact your SAP system administrator. They can check the system logs and manage traces at a higher level.
  
  
  
  Related Information:
