• What is the cause and solution for SAP error message SMMSS_DDIC011 - Clustered CS index cannot be created in tables with existing indexes ?

  The SAP error message SMMSS_DDIC011 indicates that there is an issue with creating a clustered column store (CS) index on a table that already has existing indexes. This error typically arises during the process of trying to optimize or modify the database schema, particularly when working with SAP HANA databases.
  
  Cause:
  The primary cause of this error is that a clustered column store index cannot coexist with existing non-clustered indexes on the same table. In SAP HANA, a table can only have one clustered index, and if there are already existing indexes (especially non-clustered ones), the system will not allow the creation of a new clustered index.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Existing Indexes: Check the existing indexes on the table that is causing the error. You can do this by using SQL commands or through the SAP HANA Studio.
  SELECT * FROM M_INDEXES WHERE TABLE_NAME = 'your_table_name';
  
  
  Drop Existing Indexes:
