• What is the cause and solution for SAP error message TPDA_SCRIPT026 - Standalone trace analysis will be started in a parallel session ?

  The SAP error message TPDA_SCRIPT026 indicates that a standalone trace analysis is being initiated in a parallel session. This message typically arises in the context of performance analysis or debugging within the SAP system, particularly when using transaction codes related to tracing or performance monitoring.
  Cause:
  The error message can occur due to several reasons:
  
  Concurrent Sessions: The system may already be running a trace analysis in another session, and the attempt to start a new one is being blocked.
  Configuration Issues: There may be configuration settings that prevent multiple trace analyses from running simultaneously.
  User Permissions: The user may not have the necessary permissions to start a new trace session if one is already active.
  System Load: High system load or resource constraints may also lead to this message being displayed.
  
  Solution:
  To resolve the issue, you can try the following steps:
  
  
  Check Active Sessions: Verify if there is already an active trace analysis session. You can do this by checking the transaction codes like ST01 (System Trace) or ST05 (SQL Trace) to see if a trace is currently running.
  
  
  End Existing Trace: If you find an active trace session that is no longer needed, you can stop it. This can usually be done from the same transaction code where the trace was started.
  
  
  User Permissions: Ensure that your user account has the necessary permissions to start a trace. You may need to consult with your SAP Basis administrator to check your roles and authorizations.
  
  
  System Performance: If the system is under heavy load, consider waiting for a less busy time to start the trace. You can also check system performance metrics to identify any bottlenecks.
  
  
  Parallel Session Management: If you need to run multiple traces, consider using different user sessions or adjusting the configuration settings to allow for parallel trace sessions, if applicable.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to tracing and performance analysis for any specific configurations or limitations that may apply to your version of SAP.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as ST01 (System Trace), ST05 (SQL Trace), and ST12 (Combined Trace) for performance analysis.
  SAP Notes: Check SAP Notes for any known issues or updates related to tracing and performance analysis.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
