• What is the cause and solution for SAP error message RSMSS_ANALYZER_MSG168 - Index &1 should be created with option COLUMNSTORE=&2 ?

  The SAP error message RSMSS_ANALYZER_MSG168 indicates that an index in the SAP HANA database should be created with a specific option for column store. This message typically arises during the analysis of database performance or when executing certain queries that require specific indexing strategies.
  Cause:
  The error occurs when the system detects that an index is not optimized for columnar storage, which is essential for performance in SAP HANA. The message specifies that the index should be created with the COLUMNSTORE option set to a particular value (e.g., TRUE or FALSE). This is important because SAP HANA is designed to work efficiently with columnar data storage, and using the correct indexing strategy can significantly improve query performance.
  Solution:
  To resolve this error, you need to create or modify the index in question with the appropriate COLUMNSTORE option. Here are the steps you can follow:
  
  
  Identify the Index: Determine which index is causing the error. The error message should specify the index name (denoted as &1).
  
  
  Check Current Index Configuration: Use SQL commands or the SAP HANA Studio to check the current configuration of the index.
  
  
  Create or Alter the Index:
  
  If the index does not exist, you can create it with the correct options. For example:
  CREATE INDEX <index_name> ON <table_name> (<column_list>) WITH (COLUMNSTORE = <desired_value>);
  
  If the index already exists and needs to be altered, you may need to drop it and recreate it with the correct options, as altering an index's storage type is not typically supported directly.
  
  
  
  Test the Changes: After creating or modifying the index, run the queries that previously generated the error to ensure that the issue is resolved.
  
  
  Monitor Performance: After making changes, monitor the performance of the database to ensure that the changes have had the desired effect.
  
  
  Related Information:
  
  SAP HANA Documentation: Refer to the official SAP HANA documentation for detailed information on indexing strategies and best practices.
  Performance Tuning: Consider reviewing other performance tuning options in SAP HANA, such as partitioning, data modeling, and query optimization.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error message.
  
  If you continue to experience issues or if the error persists after making the changes, consider reaching out to SAP support for further assistance.
