  The SAP error message RS2HANA_VIEW134 typically indicates an issue with the configuration of an external SAP HANA view, specifically related to the aggregation of key figures. This error arises when the system cannot perform client-side aggregation for a specified key figure in the HANA view.
  Cause:
  
  Missing Aggregation Settings: The key figure in question may not have the necessary aggregation settings defined in the HANA view.
  Incompatible Data Types: The data types of the key figure may not be compatible with the expected aggregation functions.
  Incorrect View Definition: The HANA view may not be correctly defined to allow for client-side aggregation.
  Data Model Issues: There may be issues with the underlying data model that prevent proper aggregation.
  
  Solution:
  
  
  Check Key Figure Settings:
  
  Go to the HANA view definition and verify that the key figure is set up correctly for aggregation. Ensure that the aggregation type (e.g., SUM, AVG) is defined.
  
  
  
  Review Data Types:
  
  Ensure that the data types of the key figure are compatible with the aggregation functions being used. If necessary, adjust the data types in the HANA view.
  
  
  
  Modify HANA View:
  
  If the view is not correctly defined, you may need to modify it. Ensure that the key figure is included in the aggregation logic of the view.
  
  
  
  Check Data Model:
  
  Review the underlying data model to ensure that it supports the required aggregations. This may involve checking relationships between tables and ensuring that the necessary joins are in place.
  
  
  
  Test the View:
  
  After making changes, test the HANA view to ensure that the key figure can now be aggregated correctly.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for specific guidance on the error message and best practices for defining HANA views.
