  The SAP error message RS2HANA_VIEW151 indicates that a navigation attribute is excluded from the external SAP HANA view. This typically occurs when you are working with SAP BW (Business Warehouse) and trying to create or manage a HANA-optimized view.
  Cause:
  The error can arise due to several reasons:
  
  Navigation Attribute Configuration: The navigation attribute may not be properly configured in the InfoObject or the data model.

  Incompatibility: The navigation attribute may not be compatible with the HANA view due to data type issues or other constraints.
