  The SAP error message RS2HANA_VIEW148 typically indicates an issue with an external SAP HANA view that is being used for a Multi-Dimensional (MD) model with a hierarchy. This error can arise due to various reasons, including configuration issues, data model inconsistencies, or problems with the underlying HANA view itself.
  Causes:
  
  Invalid HANA View: The HANA view may not be correctly defined or may have errors in its SQL logic.
  Hierarchy Issues: If the hierarchy structure is not properly defined or if there are inconsistencies in the hierarchy data, it can lead to this error.
  Data Model Configuration: The configuration of the data model in SAP BW/4HANA may not align with the HANA view, leading to compatibility issues.
  Authorization Issues: Lack of proper authorizations to access the HANA view can also trigger this error.
  Data Type Mismatches: Mismatches between the expected data types in the BW model and the actual data types in the HANA view can cause errors.
  
  Solutions:
  
  Check HANA View Definition: Review the SQL logic and structure of the HANA view to ensure it is correctly defined and does not contain errors.
  Validate Hierarchy: Ensure that the hierarchy is correctly defined in the BW model and that the data in the HANA view supports the hierarchy structure.

  Check Authorizations: Verify that the user has the necessary authorizations to access the HANA view and the associated data.
  Data Type Alignment: Ensure that the data types in the BW model match those in the HANA view. Adjust the model or the view as necessary to resolve any mismatches.
