TheKeep Flagproperty in an aggregation node ensures that columns not directly requested by a query are still included in the calculation process if they are critical for the correctness of the result. For example, these columns may serve as grouping or filter criteria in intermediate processing stages, even if not explicitly displayed in the final query output.

For a calculation view of typeCUBE, the default top view node is theAggregationnode. This node summarizes data based on specified grouping and performs aggregations, making it suitable for analytical purposes and star schemas.

The input parameters of calculation view B might not be proposed as source parameters because they are already mapped in another calculation view. SAP HANA restricts the re-mapping of input parameters that have already been assigned to maintain consistent logic and avoid conflicts. When input parameters are pre-mapped in one calculation view, they cannot be reused as source parameters elsewhere without unlinking the prior mapping.

When theNull Handlingproperty is set for an attribute in SAP HANA, and no default value is provided, a null value in a column of typeNVARCHARis displayed as an empty string (""). This default behavior ensures clarity in data presentation, especially in text fields where nulls are typically replaced with a blank representation.
