In SAP HANA, orphan nodes in a hierarchy are nodes that do not have a parent. To handle orphan nodes, you have the following options:

C. Assign them to an existing node at the root level.

This approach involves assigning orphan nodes to an existing node at the root level, effectively integrating them into the hierarchy.

D. Define them as additional root nodes.

This method treats orphan nodes as separate root nodes, allowing them to exist independently at the top level of the hierarchy.

These options enable you to manage orphan nodes by either integrating them into the existing hierarchy structure or allowing them to exist as independent root nodes, depending on your specific requirements.

If the account number is not masked in calculation view A, it indicates that masking was not defined in calculation view A. Masking rules must be explicitly defined at every level where data is exposed, as they are not inherited from underlying views.

The key steps to implement currency conversion in a calculation view are:

Assign Semantic Type:Ensure that the column has the correct semantic type for currency conversion.

Enable the Measure for Conversion:Mark the measure as convertible.

Choose Client, Source, and Target Currencies:Define the currencies involved in the conversion.

Choose Conversion Date and Rate Type:Specify the date and the type of conversion rate (e.g., average, spot rate).

This structured process ensures accurate and consistent currency conversions in your data models.(Reference: SAP HANA Currency Conversion Guide)

The "Ignore multiple outputs for filters" property in a calculation view ensures that filters are applied consistently and correctly at thelowest node. This setting forces filters to be applied as early as possible in the data flow, ensuring that redundant or incorrect data processing does not occur at higher nodes. This improves performance and maintains the integrity of the filter logic.

AnInner Joinsupports temporal conditions in SAP HANA calculation views. Temporal conditions involve filtering data based on time-based attributes, such as effective dates or validity periods. Inner joins are capable of including such conditions directly in the join logic to ensure that only matching records based on the temporal criteria are included in the results.

Dynamic (A):Analytic privileges can dynamically restrict data based on runtime parameters.

SQL Expression (B):SQL expressions define specific conditions for data access, offering flexibility in analytic privilege design.

Attributes (E):Attributes are standard components for defining static or dynamic access rules based on attribute values.

Options C and D (Hierarchy function and Graph) are not standard methods for defining analytic privileges.

Unfolding is a query optimization technique where parts of a calculation view are translated into SQL. Consequences include:

Count-distinct results are incorrect (B):The unfolding process may not preserve distinct counting logic correctly, potentially leading to inaccuracies.

SQL compilation time increases (C):The complexity of unfolded SQL queries can lead to longer compilation times due to the intricate relationships and data structures involved.

Option A is incorrect because unfolding does not relate to static caching, and D is partially correct but not as significant as B and C.

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.

If Table B is not pruned in a referential join, the possible issues could be:

C. The Keep flag is activated for the Customer column: This prevents pruning by forcing the inclusion of the column in query execution.

D. Integrity constraint is set to RIGHT: This setting implies that Table B data must always be considered in the join, disabling pruning.

Pruning depends on join conditions and flags; ensuring no unnecessary constraints is essential for proper optimization.
