• What is the cause and solution for SAP error message E2E_TESTING028 - ON: SQL/buffer trace activated by &1 (trace user: &2) ?

  The SAP error message E2E_TESTING028 indicates that a SQL or buffer trace has been activated in the system. This message typically arises in the context of performance analysis or debugging, where tracing is used to monitor database interactions or buffer accesses.
  Cause:
  The error message is triggered when a SQL or buffer trace is activated by a specific user. The placeholders &1 and &2 in the message represent the trace type (SQL or buffer) and the user who activated the trace, respectively. This can happen for several reasons:
  
  A user has manually activated the trace for performance analysis.
  A background job or process has triggered the trace.
  A developer or administrator is troubleshooting a specific issue and has enabled tracing.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Identify the User and Trace Type: Check the user (&2) who activated the trace and the type of trace (&1) that is currently active. This information can help you understand the context of the trace.
  
  
  Deactivate the Trace: If the trace is no longer needed, you can deactivate it. This can typically be done using transaction codes:
  
  For SQL trace: Use transaction ST05 (SQL Trace) and deactivate the trace.
  For buffer trace: Use transaction ST02 (Tune Summary) to deactivate the buffer trace.
  
  
  
  Review Trace Settings: If the trace was activated for a specific reason (e.g., performance issues), review the trace logs to analyze the performance bottlenecks or issues. You can use the trace data to optimize SQL queries or buffer usage.
  
  
  Consult Documentation: If you are unsure about the implications of deactivating the trace or need further assistance, consult SAP documentation or reach out to your SAP Basis team for guidance.
  
  
  Monitor System Performance: After deactivating the trace, monitor the system performance to ensure that the issue has been resolved and that there are no adverse effects from the trace deactivation.
