• What is the cause and solution for SAP error message RS2HANA_VIEW090 - External SAP HANA view: Key figure &1: Aggregation type &2 not supported ?

  The SAP error message RS2HANA_VIEW090 typically indicates an issue with the aggregation type of a key figure in an external SAP HANA view. This error arises when the aggregation type specified for a key figure is not supported in the context of the HANA view being used.
  Cause:
  
  Unsupported Aggregation Type: The key figure in question has an aggregation type that is not compatible with the HANA view. Common aggregation types include SUM, COUNT, AVERAGE, etc. If the key figure is set to an aggregation type that HANA does not support for that specific context, this error will occur.
  Data Model Issues: There may be inconsistencies or misconfigurations in the data model that lead to this error. For example, if the key figure is defined in a way that does not align with the underlying data structure or the intended use in the HANA view.
  View Definition: The definition of the HANA view itself may not be correctly set up to handle the specified aggregation type for the key figure.
  
  Solution:
  
  Check Aggregation Type: Review the aggregation type of the key figure in the HANA view definition. Ensure that it is set to a supported type. If necessary, change the aggregation type to one that is compatible with HANA.
  Modify Key Figure Definition: If the key figure is defined in a way that is not compatible with the HANA view, consider modifying its definition. This may involve changing the aggregation type or adjusting how the key figure is calculated.
  Review HANA View Logic: Examine the logic of the HANA view to ensure that it is correctly set up to handle the key figures and their respective aggregation types. This may involve checking joins, filters, and other components of the view.
  Consult Documentation: Refer to SAP documentation for the specific version of HANA you are using to understand the supported aggregation types and any limitations that may apply.
  Testing: After making changes, test the HANA view to ensure that the error is resolved and that the key figures are aggregating correctly.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on supported aggregation types in HANA views.
