• What is the cause and solution for SAP error message 0S065 - Table buffer trace is not switched on ?

  The SAP error message 0S065: Table buffer trace is not switched on typically indicates that the table buffering trace is not enabled for the specific table you are trying to analyze or monitor. This can occur in various scenarios, especially when you are working with performance analysis or debugging issues related to table buffering.
  Cause:
  
  Table Buffering Not Enabled: The most common cause is that the table in question does not have buffering enabled in its definition. In SAP, not all tables are buffered by default, and some may require explicit configuration to enable buffering.
  Trace Not Activated: The trace for monitoring the buffered table may not be activated in the system settings.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to view or activate the buffer trace.
  
  Solution:
  
  
  Check Table Buffering Settings:
  
  Go to the Data Dictionary (transaction SE11).
  Enter the name of the table in question and check its properties.
  Ensure that the buffering option is set to "Buffering" (e.g., "Single Record" or "Full Table") in the table definition.
  
  
  
  Activate Buffer Trace:
  
  If buffering is enabled, you may need to activate the buffer trace. This can typically be done using transaction ST02 (Tune Summary) or ST04 (Database Performance).
  In ST02, navigate to the "Buffer" tab and check if the buffer trace is activated for the relevant table.
  
  
  
  User Authorizations:
  
  Ensure that the user has the necessary authorizations to access and modify the buffer settings. This may require assistance from a system administrator.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may provide additional guidance or fixes related to this error message. You can search for notes in the SAP Support Portal.
  
  
  
  Restart the Application:
  
  In some cases, restarting the application or the relevant services may help in resolving temporary issues related to buffering.
  
  
  
  Related Information:
  
  Buffering Types: Understand the different types of buffering available in SAP (e.g., Full Buffering, Single Record Buffering, No Buffering) and their implications on performance and data consistency.
  Performance Monitoring: Familiarize yourself with performance monitoring tools in SAP, such as ST02, ST04, and ST05, which can help diagnose issues related to database performance and buffering.
  SAP Documentation: Refer to the official SAP documentation for detailed information on table buffering and performance tuning.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis team or reach out to SAP support for further assistance.
