• What is the cause and solution for SAP error message BRAIN_DEV108 - No indexes are created for tables in SAP HANA systems ?

  The SAP error message BRAIN_DEV108 indicates that no indexes are created for tables in SAP HANA systems. This can occur in various scenarios, particularly when working with SAP BW (Business Warehouse) or SAP HANA modeling.
  Cause:
  
  Missing Indexes: The primary cause of this error is that the tables in the SAP HANA database do not have the necessary indexes created. Indexes are crucial for optimizing query performance and ensuring efficient data retrieval.
  Modeling Issues: If the data model is not properly defined or if there are issues with the data source, it may lead to the absence of indexes.
  Configuration Problems: There may be configuration issues in the SAP BW or HANA system that prevent the creation of indexes.
  Data Volume: In some cases, if the data volume is low, the system may not create indexes automatically.
  
  Solution:
  
  Create Indexes Manually: You can manually create indexes for the affected tables using SQL commands in the SAP HANA Studio or through the SAP HANA Database Explorer. For example:
  CREATE INDEX index_name ON table_name (column_name);
  
  Check Data Model: Review the data model in SAP BW or HANA to ensure that it is correctly defined. Make sure that all necessary attributes and measures are included.
  Re-activate InfoObjects: If you are working with SAP BW, try re-activating the InfoObjects or InfoProviders associated with the data model. This can sometimes trigger the creation of indexes.
  Use the BW Modeling Tools: In the BW Modeling Tools, you can check the settings for the InfoProvider and ensure that the indexes are set to be created.
  Database Administration: Consult with your database administrator to ensure that the database settings allow for index creation and that there are no restrictions in place.
  Performance Optimization: If the issue persists, consider reviewing the performance optimization settings in SAP HANA to ensure that the system is configured to create indexes as needed.
