• What is the cause and solution for SAP error message AD920 - Logs older than & were deleted ?

  The SAP error message AD920 indicates that logs older than a specified retention period have been deleted. This message typically arises in the context of the SAP Application Server, particularly when dealing with log files related to application logs, system logs, or other types of logs that are managed by the system.
  Cause:
  
  Log Retention Policy: SAP systems have a log retention policy that automatically deletes logs older than a certain age to manage disk space and maintain system performance.
  Configuration Settings: The retention period for logs is defined in the system configuration. If the logs exceed this period, they will be deleted automatically.
  Manual Deletion: Logs may also be deleted manually by an administrator or through a scheduled job.
  
  Solution:
  
  Check Log Retention Settings: Review the configuration settings for log retention in your SAP system. You can do this by checking the relevant parameters in transaction codes like RZ10 (for profile parameters) or SCC4 (for client settings).
  Adjust Retention Period: If necessary, adjust the retention period to keep logs for a longer duration. This can be done by modifying the relevant profile parameters (e.g., rslg/retention_time).
  Log Archiving: Implement a log archiving strategy to move older logs to a different storage location instead of deleting them. This can be done using transaction SARA for archiving.
  Monitoring: Set up monitoring to alert you when logs are nearing their retention limits, so you can take action before they are deleted.
  Review Deletion Jobs: Check if there are any scheduled jobs that might be deleting logs prematurely. You can review this in transaction SM37 (job monitoring).
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to log management and retention policies for specific guidance and best practices.
  Documentation: Refer to the official SAP documentation for your version of the system to understand the default settings and recommended practices for log management.
  System Performance: Regularly monitor system performance and disk space usage to ensure that log management does not negatively impact system operations.
  
  By following these steps, you can address the AD920 error message and ensure that your log management practices align with your operational needs.
