• What is the cause and solution for SAP error message LQ418 - Refresh of the statistics was started ?

  The SAP error message LQ418, which states "Refresh of the statistics was started," typically indicates that the system is in the process of refreshing the statistics for a particular data object, such as a table or an InfoCube. This message is not necessarily an error but rather an informational message indicating that a background job or process is running to update the statistics.
  Cause:
  
  Statistics Update: The system automatically refreshes statistics to ensure that the optimizer has the most current information for query performance. This can happen after data loads, changes in data, or scheduled maintenance tasks.
  Background Job: A background job may have been scheduled to refresh statistics, which can lead to this message being displayed.
  Manual Trigger: An administrator or user may have manually triggered a statistics refresh.
  
  Solution:
  
  Wait for Completion: If the message indicates that the refresh is in progress, it is usually best to wait for the process to complete. You can check the status of the job in transaction SM37 (Job Monitoring).
  Check Job Logs: If the refresh takes too long or seems to be stuck, check the job logs for any errors or warnings that might indicate a problem.
  Manual Refresh: If necessary, you can manually refresh the statistics using transaction codes like DB02 (Database Performance) or RSANWB (for InfoCubes).
  Performance Monitoring: Monitor the performance of the system to ensure that the refresh process is not impacting other operations. If it is, consider scheduling the refresh during off-peak hours.
  Consult Documentation: Refer to SAP documentation or notes for specific guidance related to your version and configuration.
