• What is the cause and solution for SAP error message ANST026 - ON: SQL trace already activated by &1 (trace user: &2) ?

  The SAP error message ANST026 indicates that an SQL trace is already activated for a specific user in the system. This can happen when a user tries to activate SQL tracing while it is already active for that user, leading to the error message.
  Cause:
  The error occurs because:
  
  The SQL trace (transaction ST05) is already enabled for the user indicated in the message.
  The system does not allow multiple activations of SQL trace for the same user session.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check Active Traces:
  
  Use transaction ST05 to check if the SQL trace is already active for the user. You can do this by navigating to the SQL Trace screen and looking for the active traces.
  
  
  
  Deactivate Existing Trace:
  
  If you find that the trace is active, you can deactivate it by selecting the "Deactivate Trace" option in transaction ST05. This will stop the current trace session.
  
  
  
  Re-activate Trace:
  
  After deactivating the existing trace, you can then re-activate the SQL trace for the user.
  
  
  
  Use a Different User:
  
  If you need to run multiple traces simultaneously, consider using a different user account to activate the SQL trace.
  
  
  
  Check for Background Jobs:
  
  If the trace is activated by a background job, you may need to wait for the job to complete or deactivate the trace from the job.
