NEW QUESTION # 35
What are some best practices for writing SQLScript for use with calculation views? Note: There are 2 correct answers to this question.
- A. Use dynamic SQL.
- B. Control the flow logic using IF-THEN-ELSE conditions.
- C. Break up large statements by using variables.
- D. Choose declarative language instead of imperative language.
Answer: C,D
NEW QUESTION # 36
In your calculation view, you want to consume a custom data source defined using SQLScript. In which type of object do you write your code?
- A. Anonymous block
- B. Table function
- C. Scalar function
- D. Procedure
Answer: B
Explanation:
To consume a custom data source defined using SQLScript, you write the SQLScript logic in atable function.
Table functions are used to return tabular data, which can then be consumed in calculation views for further processing and analysis.
NEW QUESTION # 37
Why would you implement SQL in calculation views? Note: There are 2 correct answers to this question.
- A. To implement custom functions
- B. To increase the possibilities for consumption
- C. To define dynamic analytic privileges
- D. To fine-tune performance
Answer: C,D
Explanation:
* To fine-tune performance (B):Implementing SQL in calculation views can help optimize performance by leveraging advanced SQL features and minimizing unnecessary data movement.
* To define dynamic analytic privileges (D):SQL enables the implementation of conditions for dynamic analytic privileges, ensuring fine-grained and context-sensitive data access.
Options A and C are less relevant as SQL is not primarily for expanding consumption possibilities or implementing functions, which are handled by other mechanisms in SAP HANA.
NEW QUESTION # 38

Answer: B,C
NEW QUESTION # 42
What are some of the restrictions that apply when defining parallelization blocks in calculation views? Note: There are 2 correct answers to this question.
- A. The block must start with a node that defines a table as a data source.
- B. The block must have only one start node.
- C. Only one block can be defined across a stack of calculation views.
- D. Multiple blocks can be defined only within a single calculation view.
Answer: A,C
NEW QUESTION # 43
You want to map an input parameter of calculation view A to an input parameter of calculation view B using the parameter mapping feature in the calculation view editor. However, the input parameters of calculation view B are not proposed as source parameters.
What might be the reason for this?
- A. Your source calculation view is of type DIMENSION.
- B. You selected the wrong parameter mapping TYPE.
- C. You already mapped the input parameters in another calculation view.
- D. The names of the input parameters do not match.
Answer: C
Explanation:
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.
NEW QUESTION # 44
What is the objective of calculation view instantiation?
- A. Generate an optimized run-time model based on a calling query
- B. Identify potential performance issues
- C. Trace of the run-time of a calculation view
- D. Deploy a calculation view to a production system
Answer: A
NEW QUESTION # 45
Why do you nest flowgraphs? Note: There are 2 correct answers to this question.
- A. To reduce flowgraph maintenance
- B. To improve flowgraph performance
- C. To start multiple flowgraphs at the same time
- D. To access additional node types
Answer: A,B
NEW QUESTION # 46
What are some best practices when developing calculation views? Note: There are 2 correct answers to this question.
- A. Aggregate at the lowest possible node.
- B. Include all data flow logic within one calculation view.
- C. Define filters on calculated columns.
- D. Avoid defining joins on calculated columns.
Answer: B,D
NEW QUESTION # 47
You have products that appear in table A and sometimes they also appear in table B. You want to select the products that appear ONLY in tableA. Which node type do you use?
- A. Minus
- B. Intersect
- C. Aggregation
- D. Union
Answer: A
NEW QUESTION # 48

- C. space
- D. src folder
Answer: D
NEW QUESTION # 49
In a calculation view, why would you choose the DEPRECATED setting?Note: There are 2 correct answers to this question.
- A. To lock the calculation view from further modifications
- B. To warn developers that the calculation view is no longer supported
- C. To indicate that it should not be used as a data source to other calculation views
- D. To ensure it is not exposed to reporting tools for consumption
Answer: B,D
NEW QUESTION # 50
What can you identify using Performance Analysis mode?Note: There are 2 correct answers to this question.
- A. Joins that are defined on calculated columns
- B. Expected memory consumption
- C. Information about join cardinality
- D. Usage statistics of the calculation view
Answer: A,C
NEW QUESTION # 51
You combine two tables in a join node using multiple columns in each table.
Why do you enable the dynamic join option? Note: There are 2 correct answers to this question.
- A. To ensure that the aggregation always happens after the join execution
- B. To allow data analysis at different levels of granularity with the same calculation view
- C. To ensure that the join execution uses only the join columns requested in the query
- D. To force the calculation at the relevant level of granularity, even if this level is not the grouping level defined by the query
Answer: B,C
Explanation:
TheDynamic Joinoption in SAP HANA calculation views enables flexibility when joining tables with multiple columns. The reasons for enabling it include:
* B. To allow data analysis at different levels of granularity with the same calculation view:
Dynamic joins adjust to the query's granularity requirements, enabling analysis at various levels without redesigning the calculation view.
* D. To ensure that the join execution uses only the join columns requested in the query: This ensures efficient execution by only processing the relevant columns, reducing unnecessary computations.
