• What is the cause and solution for SAP error message RS2HANA_VIEW174 - &1: Filter hierarchy on time char. in external HANA view not supported. ?

  The error message "RS2HANA_VIEW174 &1: Filter hierarchy on time char. in external HANA view not supported" typically occurs in SAP BW (Business Warehouse) when working with HANA views that involve time characteristics. This error indicates that the system is unable to apply a filter on a time characteristic in an external HANA view, which is not supported.
  Cause:
  
  Time Characteristics: The error is primarily related to the use of time characteristics in the HANA view. In SAP BW, certain operations on time characteristics, such as filtering, may not be supported when the data is sourced from an external HANA view.
  HANA View Design: The design of the HANA view may not be compatible with the BW query requirements, especially if it involves complex calculations or aggregations that do not align with BW's expectations for time-based data.
  BW Query Configuration: The configuration of the BW query may be attempting to apply filters on time characteristics that are not properly defined or supported in the underlying HANA view.
  
  Solution:
  
  Review HANA View: Check the design of the HANA view to ensure that it properly handles time characteristics. If necessary, modify the view to ensure that it can support filtering on time dimensions.
  Use BW Queries: Instead of relying on external HANA views for time-based data, consider using BW queries that are designed to handle time characteristics natively. This may involve creating a new InfoProvider or using existing ones that are compatible with time filtering.
  Adjust Query Filters: If the query is attempting to filter on a time characteristic, consider removing or adjusting the filter to see if the query can run without it. This may help identify if the filter is the root cause of the issue.
  Consult Documentation: Refer to SAP documentation or notes related to HANA views and BW queries to understand any limitations or best practices regarding time characteristics.
  SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They may provide specific notes or patches that address this issue.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide guidance on best practices for using HANA views with BW.
  BW Modeling Tools: Familiarize yourself with the BW Modeling Tools and how they interact with HANA views, especially regarding time characteristics.
  Performance Considerations: Be aware that using external HANA views can have performance implications, and ensure that the views are optimized for the queries being run.
  
  By addressing the design of the HANA view and ensuring compatibility with BW's handling of time characteristics, you can resolve the error and improve the functionality of your reports and queries.
