• What is the cause and solution for SAP error message IRWC008 - Data from DB Stats is duplicate of previous run ?

  The SAP error message IRWC008, which states "Data from DB Stats is duplicate of previous run," typically occurs in the context of database statistics collection in SAP. This error indicates that the system has detected that the data being processed is identical to the data collected in a previous run, which can happen for several reasons.
  Causes:
  
  No Changes in Data: The most common cause is that there have been no changes in the underlying database statistics since the last collection run. This can happen if the data has not been updated or modified.
  Incorrect Configuration: There may be issues with the configuration of the database statistics collection process, leading to repeated collection of the same data.
  Timing Issues: If the statistics collection is run too frequently, it may not allow enough time for changes to occur in the database, resulting in duplicate data.
  Caching Issues: Sometimes, caching mechanisms may cause the system to retrieve the same data instead of the updated statistics.
  
  Solutions:
  
  Check for Data Changes: Ensure that there have been changes in the database that would warrant a new statistics collection. If no changes have occurred, you may not need to run the statistics collection again.
  Adjust Collection Frequency: If the statistics collection is being run too frequently, consider adjusting the schedule to allow more time for data changes to occur.
  Review Configuration: Check the configuration settings for the database statistics collection to ensure they are set up correctly. This includes reviewing any parameters that control the frequency and conditions under which statistics are collected.
  Clear Cache: If caching is suspected to be an issue, consider clearing the cache or restarting the relevant services to ensure that the latest data is being processed.
  Manual Collection: If necessary, you can manually trigger the statistics collection process to ensure that it runs correctly and captures any changes that may have occurred.
