• What is the cause and solution for SAP error message RS2HANA_VIEW055 - External SAP HANA view: Query &1 is based on an aggregation level ?

  The SAP error message RS2HANA_VIEW055 typically occurs when you are trying to create or use an external SAP HANA view that is based on an aggregation level in SAP BW (Business Warehouse). This error indicates that the query you are trying to execute is not compatible with the way the aggregation level is structured.
  Cause:
  The primary cause of this error is that the query you are attempting to run is based on an aggregation level that is not suitable for direct use in an external HANA view. Aggregation levels in SAP BW are designed to summarize data, and they may not expose all the necessary details or structures required for HANA views.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Check Query Definition: Review the query definition in the BW system. Ensure that the query is not solely based on an aggregation level. If it is, you may need to create a new query that is based on a DataStore Object (DSO) or InfoCube instead.
  
  
  Use a Different Data Source: Instead of using an aggregation level, try to use a different data source that is compatible with HANA views. This could be a DSO or InfoCube that provides the necessary detail level.
  
  
  Modify the Aggregation Level: If you need to use the aggregation level, consider modifying it to ensure that it can be used in the context of the HANA view. This may involve adjusting the key figures or dimensions included in the aggregation level.
  
  
  Check HANA View Configuration: Ensure that the HANA view is correctly configured to handle the data structure you are trying to query. This includes checking the joins, filters, and any other settings that may affect the view's compatibility with the query.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to HANA views and aggregation levels for any specific guidelines or best practices that may apply to your scenario.
  
  
  Related Information:
  
  SAP BW and HANA Integration: Understanding how SAP BW integrates with HANA is crucial. HANA views can leverage BW data models, but there are specific requirements and limitations.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or fixes related to this error message.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
