• What is the cause and solution for SAP error message RSMSS_ANALYZER_MSG139 - Not all table indexes have statistics ?

  The SAP error message RSMSS_ANALYZER_MSG139 indicates that not all table indexes in the database have statistics. This can lead to suboptimal query performance because the database optimizer relies on statistics to determine the most efficient way to execute queries.
  Cause:
  The primary cause of this error is that the database statistics for certain indexes are either missing or outdated. This can happen due to various reasons, such as:
  
  Newly Created Indexes: When new indexes are created, statistics may not be automatically generated.
  Data Changes: Significant changes in the underlying data (inserts, updates, deletes) can render existing statistics outdated.
  Database Maintenance: Regular maintenance tasks may not include updating statistics for all indexes.
  
  Solution:
  To resolve this issue, you need to ensure that statistics for all relevant indexes are collected and up to date. Here are the steps you can take:
  
  
  Update Statistics:
  
  Use the database management tools or SQL commands to update statistics for the affected tables and indexes. The specific command will depend on the database system you are using (e.g., ANALYZE TABLE for Oracle, UPDATE STATISTICS for SQL Server, etc.).
  
  
  
  Schedule Regular Updates:
  
  Implement a regular maintenance schedule to update statistics periodically, especially after large data modifications.
  
  
  
  Check for Missing Statistics:
  
  Use the SAP transaction code RSMO (for the SAP BW system) to check for missing statistics and to analyze the status of your data targets.
  
  
  
  Use SAP Tools:
  
  In SAP BW, you can use the RSANALYZER transaction to analyze and manage statistics for InfoProviders.
  
  
  
  Database-Specific Tools:
  
  Depending on your database (e.g., HANA, Oracle, SQL Server), use the respective tools or commands to gather statistics.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to performance tuning and statistics management for your specific database.
  Database Documentation: Refer to the documentation for your specific database system for detailed instructions on managing statistics.
