Smart SAP Assistant

• What is the cause and solution for SAP error message RSDD_ZA028 - BWA indexes deactivated. Queries are not reading from the BWA ?

  The SAP error message RSDD_ZA028 indicates that the BWA (Business Warehouse Accelerator) indexes are deactivated, which means that queries are not able to read data from the BWA. This can lead to performance issues since the queries may fall back to reading data from the database instead of the optimized BWA.
  Causes:
  
  Index Deactivation: The BWA indexes may have been manually deactivated or not activated after a data load.
  Data Load Issues: If there were issues during the data load process, it could lead to the BWA indexes being in an inconsistent state.
  Configuration Issues: Incorrect configuration settings in the BWA or BW system can lead to deactivation.
  System Maintenance: Regular maintenance tasks or updates might have inadvertently deactivated the indexes.
  Data Model Changes: Changes in the data model (like changes in InfoObjects or InfoProviders) can lead to the need for reactivation of BWA indexes.
  
  Solutions:
  
  
  Reactivate BWA Indexes:
  
  Go to the transaction code RSA1 (Data Warehousing Workbench).
  Navigate to the InfoProvider that is causing the issue.
  Right-click on the InfoProvider and select "Manage BWA Indexes".
  Check the status of the indexes and reactivate them if they are deactivated.
  
  
  
  Check Data Load Status:
  
  Ensure that the data load process has completed successfully without errors.
  If there were errors, resolve them and reload the data.
  
  
  
  Rebuild BWA Indexes:
  
  If the indexes are corrupted or not functioning properly, you may need to rebuild them.
  This can typically be done through the same "Manage BWA Indexes" option.
  
  
  
  Review Configuration:
  
  Check the BWA configuration settings in the BW system to ensure they are correct.
  Ensure that the BWA is properly connected and configured to work with your BW system.
  
  
  
  Consult Logs:
  
  Review the system logs and BWA logs for any errors or warnings that might provide more context on why the indexes are deactivated.
  
  
  
  System Restart:
  
  In some cases, a restart of the BWA or BW system may resolve temporary issues.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1, RSD1, and RSDD for managing InfoProviders and BWA settings.
  SAP Notes: Check SAP Notes for any known issues or patches related to BWA and BW performance.
  Documentation: Review SAP documentation on BWA and BW for best practices on managing indexes and data loads.
  Performance Monitoring: Use performance monitoring tools to analyze query performance and identify if the BWA is being utilized effectively.
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with SAP support or your system administrator for further assistance.
