• What is the cause and solution for SAP error message RS2HANA_VIEW171 - &1: Hierarchy variable in FEMSN not supported. Query view not generated. ?

  The SAP error message RS2HANA_VIEW171 with the description "Hierarchy variable in FEMSN not supported. Query view not generated." typically occurs in the context of SAP BW (Business Warehouse) when working with HANA views and queries that involve hierarchy variables. This error indicates that the query view could not be generated due to the presence of a hierarchy variable that is not supported in the context of the query.
  Cause:
  
  Hierarchy Variables: The error is primarily caused by the use of hierarchy variables in the query definition. Hierarchy variables are often used to filter data based on hierarchical structures (like organizational units, product hierarchies, etc.), but they may not be supported in certain contexts, especially when generating HANA views.
  Compatibility Issues: The specific version of SAP BW or the HANA database may have limitations regarding the use of hierarchy variables in queries.
  Query Design: The design of the query may not be compatible with the HANA view generation process, particularly if it involves complex hierarchies or unsupported features.
  
  Solution:
  
  Remove Hierarchy Variables: If possible, modify the query to remove hierarchy variables. Instead, consider using regular characteristic filters or other means to achieve the desired filtering without relying on hierarchy variables.
  Check Query Design: Review the query design to ensure that it adheres to the best practices for HANA views. Simplifying the query or breaking it down into smaller components may help.
  Update SAP BW: Ensure that you are using the latest version of SAP BW and HANA. Sometimes, updates include fixes for known issues or enhancements that improve compatibility.
  Consult Documentation: Refer to the SAP documentation for your specific version to understand the limitations and supported features regarding hierarchy variables in HANA views.
  SAP Support: If the issue persists, consider reaching out to SAP Support for assistance. They may provide insights specific to your environment or version.
