• What is the cause and solution for SAP error message TPDA375 - Ony one performance trace is supported ?

  The SAP error message TPDA375, which states "Only one performance trace is supported," typically occurs when you attempt to activate multiple performance traces in the SAP system simultaneously. This limitation is due to the way performance tracing is implemented in SAP, where only one trace can be active at a time for a given user session.
  Cause:
  
  The error is triggered when a user tries to start a new performance trace (using transaction ST01 or ST05) while another trace is already active for the same user or session.
  This can happen if a user forgets to stop an existing trace before starting a new one.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Stop the Existing Trace:
  
  Go to the transaction where the trace was started (e.g., ST01 or ST05).
  Stop the currently active trace. In ST01, you can do this by selecting "Deactivate Trace" or in ST05 by selecting "Deactivate Trace."
  
  
  
  Start a New Trace:
  
  After ensuring that no other traces are active, you can start a new performance trace.
  
  
  
  Check for Other Sessions:
  
  If you are working in a multi-session environment (e.g., multiple SAP GUI sessions), ensure that no other session is running a trace for the same user.
  
  
  
  Use Different Users:
  
  If you need to trace multiple processes simultaneously, consider using different user accounts for each trace.
  
  
  
  Related Information:
