• What is the cause and solution for SAP error message RSMSS_ANALYZER_MSG114 - Clustered index has been created in database ?

  The SAP error message RSMSS_ANALYZER_MSG114 indicates that a clustered index has been created in the database, which can lead to performance issues or conflicts with the SAP system's expectations regarding database structure. This message typically arises in the context of SAP's database performance analysis tools, particularly when using the SAP HANA database or other relational databases.
  Cause:
  
  Database Configuration: The error usually occurs when a clustered index is created on a table that SAP expects to be non-clustered. This can happen due to manual changes made to the database schema or through automated processes that create indexes.
  Performance Issues: Clustered indexes can affect the performance of certain queries, especially if they are not aligned with how SAP accesses the data.
  SAP Recommendations: SAP has specific recommendations for database design and indexing to ensure optimal performance. Deviating from these recommendations can lead to issues.
  
  Solution:
  
  Review Indexes: Check the indexes on the affected table. You can use SQL queries to list the indexes and their types.
  SELECT * FROM sys.indexes WHERE object_id = OBJECT_ID('YourTableName');
  
  Remove or Alter the Clustered Index: If the clustered index is not necessary, consider dropping it or altering it to a non-clustered index. Be cautious and ensure that this change does not negatively impact other parts of the application.
  DROP INDEX YourClusteredIndexName ON YourTableName;
  or
  CREATE NONCLUSTERED INDEX YourNewIndexName ON YourTableName (YourColumnName);
  
  Consult SAP Documentation: Refer to SAP's official documentation or notes related to database performance and indexing. This can provide insights into best practices and recommendations specific to your SAP version and database.
  Test Changes: After making changes, thoroughly test the application to ensure that performance is improved and that no new issues have been introduced.
  Monitor Performance: Use SAP's performance monitoring tools to observe the impact of the changes on database performance.
