• What is the cause and solution for SAP error message RS2HANA_VIEW118 - External SAP HANA view: Key figure '&1': local aggregation ignored ?

  The SAP error message RS2HANA_VIEW118 indicates that there is an issue with the aggregation of key figures in an external SAP HANA view. Specifically, the message states that local aggregation for a key figure is being ignored. This typically occurs when the system is unable to perform local aggregation due to the way the data is structured or the settings in the view.
  Cause:
  
  Aggregation Settings: The key figure may not be set up correctly for aggregation in the HANA view. This can happen if the key figure is defined in a way that does not allow for local aggregation.
  Data Model: The underlying data model may not support the type of aggregation being attempted. For example, if the key figure is based on a calculation that cannot be aggregated locally.
  Join Conditions: If the view involves complex joins or unions, the system may not be able to determine how to aggregate the data correctly.
  Incompatible Data Types: If the data types of the key figures or dimensions involved in the aggregation are incompatible, it can lead to this error.
  
  Solution:
  
  Review Key Figure Definition: Check the definition of the key figure in the HANA view. Ensure that it is set up for aggregation and that the aggregation type is appropriate (e.g., SUM, AVG).
  Simplify the Data Model: If possible, simplify the data model by reducing the complexity of joins or unions. This can help the system better understand how to aggregate the data.
  Check Aggregation Settings: Ensure that the aggregation settings in the HANA view are correctly configured. This includes checking the properties of the key figures and dimensions.
  Data Type Compatibility: Verify that the data types of the key figures and dimensions are compatible for aggregation. If necessary, adjust the data types to ensure compatibility.
  Test with Sample Data: Run tests with sample data to see if the issue persists. This can help isolate the problem and determine if it is data-related or configuration-related.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional insights or updates regarding this error message.
  HANA Studio: Use SAP HANA Studio or SAP Web IDE to analyze the view and its components. This can help identify any misconfigurations or issues.
  Performance Considerations: Be aware that local aggregation can improve performance, so resolving this issue may lead to better query performance in your reports or applications.
  Consult SAP Community: If the issue persists, consider reaching out to the SAP Community or SAP Support for further assistance.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
