• What is the cause and solution for SAP error message RS2HANA_VIEW177 - Query View with NCUM key figure and hierarchy filter not supported ?

  The SAP error message "RS2HANA_VIEW177: Query View with NCUM key figure and hierarchy filter not supported" typically occurs in the context of SAP BW (Business Warehouse) when working with HANA views. This error indicates that there is an issue with the configuration of a query view that includes a Non-Cumulative (NCUM) key figure along with a hierarchy filter, which is not supported in the current setup.
  Cause:
  
  
  Non-Cumulative Key Figures: Non-Cumulative key figures are designed to represent values that do not accumulate over time, such as stock levels or balances. They are typically used in scenarios where the values are not additive.
  
  
  Hierarchy Filters: Hierarchies are used to represent data in a structured manner, allowing users to drill down into data. However, applying a hierarchy filter on a Non-Cumulative key figure can lead to inconsistencies in the data representation.
  
  
  Compatibility Issues: The combination of NCUM key figures and hierarchy filters may not be supported in the version of SAP BW or HANA you are using, leading to this error.
  
  
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Remove Hierarchy Filter: If possible, remove the hierarchy filter from the query view that uses the NCUM key figure. This may allow the query to execute without errors.
  
  
  Change Key Figure Type: If the business requirement allows, consider changing the NCUM key figure to a cumulative key figure (CUM) if it makes sense for your data model. This change may enable the use of hierarchy filters.
  
  
  Modify Query Design: Redesign the query to avoid the combination of NCUM key figures and hierarchy filters. This may involve creating separate queries or views that do not conflict with the limitations.
  
  
  Check SAP Notes: Look for any relevant SAP Notes or updates that may address this issue. SAP frequently releases updates and patches that may resolve compatibility issues.
  
  
  Consult Documentation: Review the SAP BW and HANA documentation for any specific guidelines or limitations regarding the use of NCUM key figures and hierarchy filters.
  
  
  Engage SAP Support: If the issue persists and you cannot find a suitable workaround, consider reaching out to SAP Support for assistance. They may provide insights specific to your version and configuration.
  
  
  Related Information:
  
  SAP BW Documentation: Review the official SAP BW documentation for best practices on key figures and query design.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Training and Resources: Consider training resources or workshops on SAP BW and HANA to better understand the limitations and capabilities of the system.
  
  By following these steps, you should be able to address the error and improve the performance and accuracy of your SAP BW queries.
