• What is the cause and solution for SAP error message OA2DEVTRC018 - SQL Trace already running ?

  The SAP error message OA2DEVTRC018: SQL Trace already running typically occurs when you attempt to start SQL tracing in an SAP system while a trace is already active. This can happen in various scenarios, such as when using transaction codes like ST05 (SQL Trace) or ST12 (Single Transaction Analysis).
  Cause:
  
  Active SQL Trace: The most common cause is that an SQL trace is already running for the user or session. This can happen if the trace was not stopped properly or if another user/session has initiated a trace.
  Multiple Attempts: Attempting to start a trace multiple times without stopping the previous one.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Stop the Active Trace:
  
  Go to transaction code ST05.
  Check if there is an active trace for your user or session.
  If there is, stop the trace by clicking on the "Deactivate Trace" button.
  
  
  
  Check for Other Sessions:
  
  If you are not able to stop the trace, check if another user or session has started the trace. You may need to coordinate with other users or administrators to stop the trace.
  
  
  
  Use Transaction ST12:
  
  If you are using ST12, ensure that you are not trying to start a new trace while one is already running. You can stop the trace in the same way as in ST05.
  
  
  
  Restart the Session:
  
  If you are unable to stop the trace due to session issues, you may consider logging out and logging back into the SAP system. This will reset your session and should allow you to start a new trace.
  
  
  
  Check for System-Wide Traces:
  
  In some cases, system-wide traces may be running. You can check this in transaction SM66 (Global Work Process Overview) to see if any background jobs or other users are running traces.
