• What is the cause and solution for SAP error message RSDU_REPART793 - Tables of star InfoCube &1 will be created column-organized ?

  The SAP error message RSDU_REPART793 indicates that the tables of a star InfoCube will be created in a column-oriented format. This message typically arises during the process of creating or modifying an InfoCube in SAP BW (Business Warehouse) when the system determines that the InfoCube should be stored in a columnar format rather than the traditional row-oriented format.
  Cause:
  
  Column-Store Configuration: The system is configured to use a column-store database (like SAP HANA) for storing InfoCubes. This is often the case in environments where performance and storage efficiency are prioritized.
  Data Model: The specific characteristics of the InfoCube, such as the number of dimensions and measures, may lead the system to decide that a column-oriented storage is more efficient.
  Version Compatibility: The version of SAP BW or the underlying database may also influence how data is stored.
  
  Solution:
  
  Accept the Column-Store Format: If the column-oriented format is acceptable for your use case, you can proceed with the creation of the InfoCube as is. Columnar storage can provide performance benefits for analytical queries.
  Review Configuration: If you believe that the InfoCube should not be created in a column-oriented format, review the configuration settings in your SAP BW system. Check the settings related to the database and InfoCube properties.
  Consult Documentation: Refer to SAP documentation regarding InfoCube creation and columnar storage to understand the implications and benefits of using a column-oriented format.
  Performance Testing: If you are unsure about the performance implications, consider conducting performance tests with both formats to see which one meets your needs better.
  
  Related Information:
  
  Column-Store vs. Row-Store: Understand the differences between column-oriented and row-oriented storage. Columnar storage is generally more efficient for read-heavy analytical workloads, while row-oriented storage may be better for transactional workloads.
  SAP HANA: If you are using SAP HANA, familiarize yourself with its capabilities and how it handles data storage. HANA is optimized for columnar storage and can significantly improve query performance.
  SAP Notes and Community: Check SAP Notes for any specific issues or updates related to this error message. The SAP Community forums can also be a valuable resource for insights from other users who may have encountered similar situations.
  
  In summary, the RSDU_REPART793 message is not necessarily an error but rather an informational message indicating the storage format of the InfoCube. Depending on your requirements, you can either accept this format or investigate further to ensure it aligns with your data strategy.
