• What is the cause and solution for SAP error message RSSDA016 - Statistics of type HISTOGRAM will be created ?

  The SAP error message RSSDA016 indicates that statistics of type HISTOGRAM will be created for a specific database table or index. This message is not necessarily an error but rather an informational message that indicates the system is generating histogram statistics for the specified object.
  Cause:
  The creation of histogram statistics is typically triggered by the following scenarios:
  
  Database Optimization: The database optimizer requires detailed statistics to make informed decisions about query execution plans. Histogram statistics provide a more granular view of data distribution within a column.
  Automatic Statistics Update: If the database is set to automatically update statistics, it may create histogram statistics when it detects that the existing statistics are outdated or insufficient for optimal query performance.
  Manual Statistics Collection: A database administrator may have manually initiated the collection of statistics for performance tuning purposes.
  
  Solution:
  
  Allow the Process to Complete: If the message appears during a statistics update process, allow the system to complete the operation. This is a normal part of database maintenance.
  Check Database Settings: Ensure that the database settings for statistics collection are configured correctly. This includes settings for automatic updates and the frequency of statistics collection.
  Review Statistics: After the histogram statistics are created, review them to ensure they accurately reflect the data distribution. You can use transaction codes like ST03N or ST04 to analyze performance and statistics.
  Manual Collection: If necessary, you can manually collect statistics using the appropriate SQL commands or through SAP transaction codes like DB02 or DBACOCKPIT.
  Monitor Performance: After the statistics are created, monitor the performance of queries that utilize the affected table or index to ensure that the changes have a positive impact.
