  Cause

  Solution
  To resolve this error, you can take the following steps:

  Modify the HANA View: If you have access to the HANA view, you may need to modify it to accommodate the required aggregation. This could involve changing the SQL logic or the way the data is being aggregated.
  
  
  Use Standard Aggregation: If possible, use standard aggregation methods that are known to be supported by HANA views. This may involve rethinking how the data is aggregated in your reports or queries.
  
  
  Consult Documentation: Refer to SAP documentation for the specific version of HANA you are using to understand the limitations and supported features regarding exception aggregation.
  
  
  Testing: After making changes, test the view to ensure that the error is resolved and that the data is being aggregated correctly.
