• What is the cause and solution for SAP error message RS_DB_DB6605 - Write-optimized DataStore object is column-organized ?

  The SAP error message RS_DB_DB6605 indicates that there is an issue with a Write-Optimized DataStore Object (DSO) that is configured as column-organized. This error typically arises in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when there is a mismatch in the expected data storage format.
  Cause:
  
  Configuration Mismatch: The error occurs when a Write-Optimized DSO is set up to use a columnar storage format, which is not supported. Write-Optimized DSOs are typically row-oriented.
  Data Model Issues: The data model may have been incorrectly defined, leading to the system trying to access or write data in an unsupported format.
  Incompatibility with HANA: If you are using SAP HANA, there may be specific configurations or settings that are not aligned with the expectations of the Write-Optimized DSO.
  
  Solution:
  
  
  Check DSO Configuration: 
  
  Go to the DataStore Object settings in the SAP BW system.
  Ensure that the DSO is configured correctly as a Write-Optimized DSO and not as a column-organized object.
  If it is incorrectly set, you may need to recreate the DSO with the correct settings.
  
  
  
  Review Data Model:
  
  Analyze the data model to ensure that all objects are compatible and correctly defined.
  If necessary, adjust the data flow or transformation logic to align with the DSO's requirements.
  
  
  
  Consult Documentation:
  
  Refer to the SAP Help Portal or relevant SAP Notes for guidance on configuring Write-Optimized DSOs and understanding their limitations.
  
  
  
  Check for Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as there may be fixes or enhancements related to this issue.
  
  
  
  Contact SAP Support:

  Related Information:
  
  Write-Optimized DSO: This type of DSO is designed for high-speed data loading and is typically used for staging data before it is transformed and loaded into a more structured format.
  Column-Organized vs. Row-Organized: Understanding the difference between these two storage formats is crucial. Column-oriented storage is optimized for read-heavy operations, while row-oriented storage is better for write-heavy operations.
  SAP BW/4HANA: If you are using SAP BW/4HANA, be aware of the specific features and limitations of the data storage options available in this environment.
  
  By following these steps, you should be able to resolve the RS_DB_DB6605 error and ensure that your Write-Optimized DSO is functioning correctly.
