• What is the cause and solution for SAP error message /SDF/ZQLM505 - SQL Monitor reorganization: &1 records deleted in history ?

  The SAP error message /SDF/ZQLM505 SQL Monitor reorganization: &1 records deleted in history typically indicates that a reorganization process has been executed in the SQL Monitor, which is part of the SAP system's performance monitoring tools. This message informs you that a certain number of records (indicated by &1) have been deleted from the history of SQL Monitor data.
  Cause:
  
  Reorganization Process: The SQL Monitor collects data on SQL statements executed in the system. Over time, this data can accumulate and may need to be reorganized to improve performance and manage storage.
  Retention Policy: The system may have a configured retention policy that dictates how long historical data is kept. When this policy is reached, older records are deleted to make room for new data.
  Manual Trigger: The reorganization could have been manually triggered by an administrator or as part of a scheduled job.
  
  Solution:
  
  Review Configuration: Check the configuration settings for the SQL Monitor to understand the retention policy and how often reorganization occurs. This can usually be done in the SAP GUI under the relevant transaction codes (e.g., SDF_MONITOR).
  Monitor Performance: After the reorganization, monitor the performance of SQL statements to ensure that the system is functioning optimally. You may want to analyze the SQL Monitor reports to identify any performance issues.
  Adjust Retention Settings: If you find that records are being deleted too frequently and you need to retain more historical data for analysis, consider adjusting the retention settings in the SQL Monitor configuration.
  Documentation: Ensure that you document any changes made to the configuration for future reference and compliance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SDF_MONITOR for SQL Monitor and SDF_SQLM for SQL performance analysis.
  SAP Notes: Check SAP Notes for any updates or patches related to SQL Monitor and its reorganization processes.
  Performance Tuning: Consider engaging in performance tuning activities if you notice that SQL performance is degrading after the reorganization.
  
  If you continue to experience issues or have specific concerns about the SQL Monitor's behavior, it may be beneficial to consult with SAP support or your system administrator for further assistance.
