What causes this issue?

Among other things, statistical information about tables (size,
distribution of values, and so on) is stored in the database system
tables (system catalog). The optimizer then analyzes this informaiton
when creating access plans for SQL statements.
For tables with variable datasets (transaction data), this statistical
information must be regularly adjusted.

System Response

The better these statistics, the better the optimizer can create plans.
Conversely, obsolete data or statistics that are missing completely can
cause poor access plans and therefore poor performance.

• What is the cause and solution for SAP error message DB6127 - The table statistics are current ?

  The SAP error message DB6127, which states "The table statistics are current," typically indicates that the database system has determined that the statistics for a particular table are up to date and do not require any further updates. This message is often encountered during database maintenance tasks, such as when running the UPDATE STATISTICS command.
  Cause:
  
  Current Statistics: The primary cause of this message is that the database has already collected and updated the statistics for the specified table, and it believes that the existing statistics are sufficient for query optimization.
  No Changes to Data: If there have been no significant changes to the data in the table since the last statistics update, the database will not see a need to refresh the statistics.
  Automatic Statistics Update: Some database systems have automatic mechanisms to update statistics, which may have already run and updated the statistics without manual intervention.
  
  Solution:
  
  Verify Table Changes: Check if there have been significant changes to the data in the table. If there have been, you may want to force an update of the statistics.
  Force Statistics Update: If you believe the statistics are outdated or not reflective of the current data distribution, you can force an update. This can usually be done with a command specific to your database system (e.g., ANALYZE TABLE or UPDATE STATISTICS).
  Check Database Configuration: Review the database configuration settings related to statistics collection. Ensure that automatic updates are enabled if you want the database to manage statistics without manual intervention.
  Consult Documentation: Refer to the documentation for your specific database system (e.g., SAP HANA, Oracle, SQL Server) for detailed instructions on managing table statistics.
  
  Related Information:
  
  Database Performance: Keeping table statistics up to date is crucial for query optimization and overall database performance. Outdated statistics can lead to inefficient query plans and slower performance.
