Question 1: Correct

Which of the following is a characteristic of ABAP Managed Database Procedures

(AMDP)?

Please choose the correct answer.

• They are written in Java

• They do not support table buffering
• They can only be used in SAP ECC systems
• They are stored in the SAP HANA database (Correct)

Explanation
ABAP Managed Database Procedures (AMDPs) are indeed stored in the SAP HANA
database. They are created and executed in the HANA database through ABAP using an
AMDP Class and AMDP Method. The implementation of AMDP is written in HANA SQL
Script language and executed on the database. So, a characteristic of ABAP Managed
Database Procedures (AMDP) is that they are stored in the SAP HANA database.

Question 2: Correct
How would you describe the function of an Interface in ABAP Object-Oriented
programming?

Please select the correct answer.

• To provide a user interface for an application

• To store data in a structured format
• To execute database transactions
• To define a set of methods that implementing classes must use (Correct)

Explanation
An interface in ABAP Object-Oriented programming is a blueprint or a contract that
defines a set of methods that a class must implement. It provides a standard way to
define the behavior of a group of related classes. Interfaces enable multiple inheritance,
polymorphism, and abstraction in ABAP OO.
Question 3: Correct
What does 'SQL pushdown' refer to in the context of ABAP development? Please choose
the correct answer.
• Pushing SQL code to the application layer for processing
• Transferring all database operations to a secondary database
• Executing data-intensive logic directly in the database layer (Correct)
• Moving SQL statements from the application server to the client side

Explanation
• SQL pushdown is a technique to improve performance by moving data-intensive
computations from the application server to the database layer, where they can
be executed more efficiently using native SQL.
• SQL pushdown reduces the amount of data transferred between the application
server and the database, as well as the memory consumption and CPU load on
the application server.
• SQL pushdown can be achieved by using various features of ABAP for SAP
HANA, such as CDS views, AMDPs, table functions, and database hints.

Question 4: Correct
Which of the following is an example of the 'Singleton' design pattern in ABAP OO?
Please choose the correct answer.
• A class that has multiple instances with shared properties
• A class that groups several related methods
• A class that is used to create complex database queries
• A class that ensures only one instance exists at any time (Correct)

Explanation
The Singleton design pattern is used when we want to ensure that only one instance of
a class is created and that it can be accessed globally. In ABAP OO, an example of the
Singleton design pattern can be seen in the usage of the global class. The global class
can be accessed from anywhere in the program, and only one instance of it is created.
So, the correct answer to your question would be: the global class in ABAP OO.
Question 5: Correct
In ABAP for SAP HANA, what is the purpose of using 'Scalar User Defined Functions' ?

Please choose the correct answer.

• To perform complex calculations on the application server

• To manage user access and permissions in the database
• To define custom functions that return a single value, executed in the
database (Correct)
• To create new data types for database tables

Explanation
The purpose of using ‘Scalar User-Defined Functions’ in ABAP for SAP HANA is to
define custom functions that return a single value, executed in the database. Scalar
User-Defined Functions are a type of user-defined functions that can be called in the
SELECT and WHERE clauses of an SQL statement. They allow the developer to
encapsulate complex algorithms into manageable, reusable code, which can then be
nested within the field list of a SELECT statement. They are written in SQL Script, a
scripting language for SAP HANA, and executed on the database layer. This enables the
developer to leverage the code pushdown paradigm and optimize the performance of
data-intensive applications. So, the purpose of using ‘Scalar User-Defined Functions’ in
ABAP for SAP HANA is indeed to define custom functions that return a single value,
executed in the database.

Question 6: Correct
How does the Side-by-Side Extensibility model benefit SAP S/4HANA Cloud customers?

Please choose the correct answer.

• By enabling extensions to be built in separate systems, such as SAP BTP

(Correct)
• By automating the extension development process
• By allowing direct modifications to the SAP core
• By reducing the need for any kind of system extensions

Explanation
The Side-by-Side Extensibility model benefits SAP S/4HANA Cloud customers by
enabling extensions to be built in separate systems, such as SAP BTP. This model
allows customers to leverage the services and capabilities of SAP BTP, such as
machine learning, AI, integration, and so on, without modifying the core SAP S/4HANA
Cloud system. This way, customers can create custom applications that are loosely
coupled with SAP S/4HANA Cloud and can access and manipulate its data using
remote APIs. This also ensures that the extensions are upgrade-stable and do not
interfere with the core system’s performance and security.
Question 7: Correct
What does ‘Extensibility’ signify within the framework of SAP S/4HANA Cloud?

Please select the correct answer.

• The capacity to add or enhance functionality without disrupting the core

(Correct)
• The ability to modify the core SAP code
• The integration of third-party software
• The process of upgrading the SAP system

Explanation
‘Extensibility’ in the context of SAP S/4HANA Cloud refers to the ability to add or
enhance functionality without disrupting the core system. This allows for customization
and adaptation of the system to meet specific business needs, while ensuring that the
core functionalities remain intact and upgrades can be carried out smoothly.

Question 8: Correct
What role does the ‘ABAP Test Cockpit’ (ATC) play in improving code quality in ABAP
development?

Please select the correct answer.

• By providing a runtime environment for testing

• By automatically correcting syntax errors
• By managing version control of ABAP programs
• By performing static code checks and analysis (Correct)

Explanation
The ‘ABAP Test Cockpit’ (ATC) enhances code quality in ABAP development by
performing static code checks and analysis. It helps to identify and rectify potential
issues early in the development process, ensuring that the code adheres to SAP’s
programming standards and best practices. This leads to more robust, efficient, and
maintainable ABAP programs.
Question 9: Correct
What is the primary benefit of code pushdown in ABAP for SAP HANA? Please choose
the correct answer.
• To simplify the syntax of ABAP code
• To increase the size of the codebase
• To enhance the user interface experience
• To improve performance by executing data-intensive operations in the
database (Correct)

Explanation
The primary benefit of code pushdown in ABAP for SAP HANA is to improve
performance by executing data-intensive operations in the database. Code pushdown
means delegating data intense calculations to the database layer1. This reduces the
number of round trips with the database, exploits the columnar characteristics of SAP
HANA, and benefits from other code-near-the-data effects, such as reduced amount of
data that needs to be transported to the upper layer. The HANA database is optimized
for this, it does all sorts of tricks e.g., parallel database reads. The end result – in theory
– is that if you “push down” data intensive calculations to the database then your
application will run significantly faster. So, the primary benefit of code pushdown in
ABAP for SAP HANA is indeed to improve performance by executing data-intensive
operations in the database.

Question 10: Correct

How does the 'Optimistic Locking' mechanism work in the ABAP RAP? Please choose
the correct answer
• By preventing any access to data during updates
• By locking the entire database during transactions
• By using timestamps to order transactions
• By allowing concurrent access and resolving conflicts during the save
(Correct)

Explanation
The ‘Optimistic Locking’ mechanism in the ABAP RAP works by allowing concurrent
access to the data and resolving conflicts during the save operation. This means that
multiple users can read and modify the same data without locking it, but only one user
can successfully save the changes. If another user tries to save the data that has been
modified by someone else, the system will detect the conflict and reject the save
request. This way, the data integrity is preserved without blocking the access for other
users.
Question 11: Correct
What is 'Service Binding' in the ABAP RAP?

Please choose the correct answer.

• It links a CDS view to a specific database

• It manages user authentication and authorization
• It binds UI elements to backend data
• It exposes a business object as a service (Correct)

Explanation
‘Service Binding’ in the ABAP RAP does not expose a business object as a service. That
is the role of the ‘Service Definition’, which describes which CDS entities of a data model
are to be exposed so that a specific business service can be enabled. The ‘Service
Binding’ is an ABAP Repository object that binds a service definition to a specific
communication protocol, such as OData V2 or OData V4. The ‘Service Binding’ defines
the service name, the binding type, and the service transport. The ‘Service Binding’
enables a service to integrate a variety of service protocols without any kind of re-
implementation. So, the correct answer is: ‘Service Binding’ in the ABAP RAP defines a
specific communication protocol for a service.

Question 12: Correct

What is the main advantage of using AMDPs over classical ABAP database procedures?

Please choose the correct answer.

• AMDPs are easier to debug.

• AMDPs allow the use of native SQL for database-specific operations. (Correct)
• AMDPs do not require knowledge of SQL.
• AMDPs can be used with any database.

Explanation
The main advantage of using ABAP Managed Database Procedures (AMDPs) over
classical ABAP database procedures is that AMDPs allow the use of native SQL for
database-specific operations12. This enables developers to optimize their ABAP code
by calling HANA database procedures from a global ABAP class3. AMDPs can process
and modify data at the database layer124, and they are able to return multiple result
sets on complex logic124. This is particularly useful when CDS views, which are
dedicated for a single set of logic and return only one result set14, encounter some
restrictions1. So, the main advantage of using AMDPs over classical ABAP database
procedures is indeed that AMDPs allow the use of native SQL for database-specific
operations.
Question 13: Correct
In the ABAP RAP, what is the purpose of 'Projections'?

Please choose the correct answer.

• To handle error logging and monitoring

• To create subsets of data for specific use cases (Correct)
• To visualize data in graphical formats
• To manage database replication

Explanation
The purpose of ‘Projections’ in the ABAP RAP is to create subsets of data for specific
use cases. Projections allow you to select only the fields that are relevant for a
particular scenario, and to apply filters or calculations on them. Projections are defined
in the behavior definition of a business object, and can be used in queries or
associations.
Question 14: Correct
What is the purpose of a 'Service Definition' in ABAP RAP?

Please choose the correct answer.

• To expose a business object as a service (Correct)

• To manage database connections
• To define the UI components
• To specify the business logic

Explanation
In ABAP RESTful Application Programming Model (RAP), a ‘Service Definition’ is used to
expose a business object as a service1. It describes which CDS entities of a data model
are to be exposed so that a specific business service, for example, Sales Order handling,
can be enabled1. It is an ABAP Repository object that describes the consumer-specific
but protocol-agnostic perspective on a data model1. You use a service definition to
define which data is to be exposed as a business service using one or more service
bindings1. A service definition itself is independent from the version or type of the
protocol that is used for the business service1. So, the purpose of a ‘Service Definition’
in ABAP RAP is indeed to expose a business object as a service.
Question 15: Correct
Such as semantics and OData, How do CDS Views support different types of
annotations?

Please choose the correct answer.

• By supporting multiple programming languages

• By providing metadata for UI rendering and data services (Correct)
• By enabling integration with non-SAP systems
• By allowing direct manipulation of database indexes

Explanation
Core Data Services (CDS) Views support different types of annotations, such as
semantics and OData, by providing metadata for UI rendering and data services.
Annotations are metadata that provide additional information about the elements of a
CDS view, such as fields, entities, or views. They can be used to describe the semantics
of the data elements, define constraints, specify default values, or provide
documentation. For example, the ABAP annotation @OData.publish:true ensures that an
OData service is created when the CDS view is activated. The annotations @UI.lineItem
ensures that a column is created5. So, CDS Views support different types of
annotations, such as semantics and OData, by providing metadata for UI rendering and
data services.

Question 16: Correct

How does the utilization of ‘Open SQL’ evolve in the context of ABAP development for
SAP HANA?

Please select the correct answer.

• Open SQL is replaced entirely by CDS views

• Open SQL is enhanced to leverage SAP HANA’s capabilities (Correct)
• Open SQL usage remains unchanged in SAP HANA
• Open SQL is no longer supported in SAP HANA

Explanation
With ABAP development for SAP HANA, Open SQL is enhanced to leverage the
capabilities of SAP HANA. This includes the ability to handle larger data volumes,
perform complex calculations, and utilize advanced features like full-text search and
predictive analysis. This makes Open SQL a powerful tool for developing efficient and
high-performing applications on SAP HANA.
Question 17: Correct
What is the advantage of using Advanced View Building techniques in CDS, In the
context of ABAP on HANA?

Please choose the correct answer.

• To build sophisticated data models leveraging database capabilities (Correct)

• To enable direct update of database tables
• To manage database transactions
• To create complex UI designs
Explanation
The advantage of using Advanced View Building techniques in Core Data Services (CDS)
in the context of ABAP on HANA is to build sophisticated data models leveraging
database capabilities. Advanced View Building with CDS allows for the creation of
semantically enriched data models that can be defined in DDL Source objects
integrated with the ABAP dictionary. This approach supports code pushdown through
view building functionality, which was not provided by open SQL. The use of CDS views
enables the optimization of applications based on open SQL. So, the advantage of using
Advanced View Building techniques in CDS, in the context of ABAP on HANA, is indeed
to build sophisticated data models leveraging database capabilities.

Question 18: Correct

Which statement about the 'AT SELECTION-SCREEN' event is true?

Please choose the correct answer.

• It is triggered after the user executes a report

• It is used to validate user input on the selection screen (Correct)
• It is used to modify the selection screen dynamically
• It occurs only once during the program execution

Explanation
The ‘AT SELECTION-SCREEN’ event is used to validate user input on the selection
screen. This event occurs after the runtime environment has passed all input data from
the selection screen to the ABAP program. The user input can be checked in this event
block, and any warning or error messages can be sent to make the fields ready for input
again. So, the statement about the ‘AT SELECTION-SCREEN’ event is true that it is used
to validate user input on the selection screen.
Question 19: Correct
In ABAP CDS Views, What is the purpose of using Associations? Please choose the
correct answer.
• To optimize the performance of CDS views
• To link CDS views with external databases
• To define relationships between different CDS views (Correct)
• To encrypt data within CDS views

Explanation
In ABAP Core Data Services (CDS) Views, the purpose of using Associations is to define
relationships between different CDS views. Associations are a part of the CDS syntax
used to define the relationship between two or more entities. This allows you to easily
query, navigate, and access related data. They are kind of Joins to fetch data from
multiple tables on Join Conditions but these are ‘JOINS ON-DEMAND’ i.e., they will only
be triggered when the user would access the required data which needs the Association
of tables1. So, the purpose of using Associations in ABAP CDS Views is indeed to
define relationships between different CDS views.

Question 20: Correct

Where do you implement non-standard operations for customized business-logic
behavior in the RESTful Application Programming model?

Please choose the correct answer.

• Determination
• Action (Correct)
• Validation
• Draft

Explanation
In the RESTful Application Programming model, you implement non-standard
operations for customized business-logic behavior using actions. Actions are self-
implemented operations that change the data of a business object entity. They are
defined in the behavior definition of the business object and implemented in the
behavior implementation class. Actions can be used to perform complex calculations,
validations, or transformations on the data. Actions can also have input parameters and
return values. So, in the RESTful Application Programming model, you implement non-
standard operations for customized business-logic behavior using actions.
Question 21: Correct
Which of the following is a key feature of ABAP CDS views?

Please choose the correct answer.

• They can be used to create updateable views

• They support complex event processing
• They require additional middleware for deployment
• They are independent of the underlying database system (Correct)

Explanation
ABAP CDS views are not independent of the underlying database system. ABAP CDS
views are platform-independent in the sense that they can be used with any database
that is supported by SAP.

Question 22: Correct

What does the ALV Grid Control provide in SAP ABAP?

Please choose the correct answer.

• An interactive and customizable table display (Correct)

• A method for data encryption
• A tool for user authentication
• A framework for mobile applications

Explanation
The ALV Grid Control in SAP ABAP provides an interactive and customizable table
display. It is a flexible tool for displaying lists. The tool provides common list operations
as generic functions and can be enhanced by self-defined options. This allows you to
use the ALV Grid Control in a large range of application programs. So, the ALV Grid
Control in SAP ABAP indeed provides an interactive and customizable table display.

Question 23: Correct

How do ABAP RESTful Application Programming Model (RAP) and SAP BTP
complement each other in the context of extensibility?

Please choose the correct answer

• RAP provides a framework for building OData services, which can be

consumed in BTP (Correct)
• BTP replaces the need for RAP in modern SAP development
• RAP is used for backend development, while BTP is for frontend only
• RAP and BTP operate independently without any interaction
Explanation
RAP and BTP complement each other in the context of extensibility by enabling cloud-
ready, SAP HANA-optimized, OData-based Fiori UI services and Web APIs in ABAP,
supporting both greenfield and brownfield development scenarios, following the clean
core principle, and leveraging the proven infrastructure of the ABAP Workbench.

Question 24: Correct

Identify a feature of the New ABAP SQL from the options below.

Please select the correct answer.

• Enhanced performance and optimization for SAP HANA (Correct)

• Exclusive use for non-HANA databases
• Limited integration with SAP HANA features
• Inability to handle complex calculations

Explanation
One of the features of the New ABAP SQL is performance optimization. With the New
ABAP SQL, developers can write optimized SQL statements that can improve the
performance of their applications. This is achieved through features such as table
expressions, subqueries, and window functions, which allow for more efficient
processing of data.

Question 25: Correct

What is a "Transport Request" in SAP ABAP?

Please choose the correct answer.

• A method to request system resources

• A user request for program execution
• A request for data from the database
• A package for transporting changes across systems (Correct)

Explanation
A “Transport Request” in SAP ABAP is indeed a package for transporting changes
across systems. It is a kind of ‘Container / Collection’ of changes that are made in the
development system. It records the information regarding the type of change, the
purpose of transport, request category, and the target system. Each Transport Request
contains one or more change jobs, also known as change Tasks. All the Tasks are
stored inside a Transport Request. So, a “Transport Request” in SAP ABAP is indeed a
package for transporting changes across systems.
Question 26: Correct
What is the role of 'Behavior Definitions' in RAP?

Please choose the correct answer.

• To define the UI behavior

• To describe the business logic of a service (Correct)
• To specify the data model
• To manage service deployment

Explanation
The role of ‘Behavior Definitions’ in RAP is to describe the business logic of a service.
Behavior definitions define the behavior of a business object in terms of allowed
actions, events, and determinations. They specify the application logic and define how
the business object behaves. Behavior definitions are a crucial part of any CDS data
model, as they determine what we can do with our data, such as creating, updating, and
deleting records. So, the role of ‘Behavior Definitions’ in RAP is indeed to describe the
business logic of a service.

Question 27: Correct

In Restful application programming, what is the advantage of using 'Managed
Transactional Processing'?

Please choose the correct answer.

• It allows direct access to the database

• It automates CRUD operations and ensures data consistency (Correct)
• It enables the use of custom SQL queries
• It provides a mechanism for offline data synchronization

Explanation
In RESTful application programming, ‘Managed Transactional Processing’ provides
significant advantages. It automates CRUD (Create, Read, Update, Delete) operations,
which can greatly simplify the development process. Additionally, it ensures data
consistency, which is crucial for maintaining the integrity of the application’s data. By
managing transactions effectively, it helps prevent data conflicts and inconsistencies
that can occur in concurrent processing environments
Question 28: Correct
In the ABAP RESTful Application Programming Model, which protocol is primarily used
for data exchange?

Please choose the correct answer.

• OData (Correct)
• HTTP
• SOAP
• MQTT

Explanation
The OData protocol is primarily used for data exchange in the ABAP RESTful Application
Programming Model. The OData protocol is used for stateless communication, and it is
through this protocol that business services are exposed. So, in the ABAP RESTful
Application Programming Model, the OData protocol is primarily used for data
exchange.

Question 29: Correct

In Object-Oriented Programming Which of the following principles is NOT a part of the
four basic principles?

Please choose the correct answer.

• Recursion (Correct)
• Inheritance
• Encapsulation
• Polymorphism
Explanation
Recursion is not one of the four basic principles of Object-Oriented Programming (OOP).
The four basic principles of OOP are:

Abstraction: This principle is about creating a simple model of the more complex real
world.

Encapsulation: This principle is about hiding the internal states and functionality of
objects.

Inheritance: This principle allows a class to be defined that has a certain set of
characteristics (such as methods and variables) and then other classes to be created
which are derived from that class.

Polymorphism: This principle allows one interface to be used for a general class of
actions.
So, in the context of Object-Oriented Programming, recursion is not a basic principle.

Question 30: Correct

What does the annotation '@ClientDependent' indicate in ABAP CDS? Please choose the
correct answer.
• The view will include the client field in the result set. (Correct)
• The view is used for client-side scripting.
• The view can only be accessed by specific clients.
• The view is independent of the client.

Explanation
If one of the data sources used in the view is client-specific, the view is client-specific. If
none of the data sources used in the view is client-specific, the view is a cross-client
view. So, if the "@ClientDependent" annotation is set, the view will include the client field
in the result set.

Question 31: Correct

How do ABAP CDS views enhance performance in comparison to conventional
database views?Please select the correct answer.
• By reducing the amount of data transferred over the network (Correct)
• By enabling client-side data processing
• By executing in the application layer instead of the database layer
• By automatically creating indexes for faster data retrieval

Explanation
ABAP CDS views can improve performance by reducing the amount of data transferred
over the network. They achieve this by pushing data-intensive computations to the
database layer rather than the application layer, thereby minimizing data transfer
between the database and the application server. This is one of the key advantages of
using ABAP CDS views over traditional database views.
Question 32: Correct
What is an In-App Extension in SAP S/4HANA Cloud?Please choose the correct answer.
• Extensions built on external platforms
• Customizations within the core of S/4HANA (Correct)
• Modifications to the SAP GUI
• Extensions using SAP Fiori apps

Explanation
In-App Extensions in SAP S/4HANA Cloud refer to customizations made within the core
of S/4HANA. These extensions allow you to adapt standard business software to your
business processes without modifying the standard software itself. This ensures that
your customizations are preserved when you upgrade your system, providing a high
degree of flexibility and adaptability.
Question 33: Correct
What is the function of the ‘Extend View’ statement in ABAP CDS?

Please select the correct answer.

• To add fields to an existing database table

• To optimize the performance of a CDS view
• To create a backup of a CDS view
• To include additional logic in an existing CDS view (Correct)

Explanation
The ‘Extend View’ statement in ABAP CDS is used to include additional logic in an
existing CDS view. This allows developers to add more fields or change the behavior of
a CDS view without modifying the original view, thereby maintaining the integrity of the
original code while extending its functionality.

Question 34: Correct

An ABAP developer is tasked with enhancing the performance of a data-intensive
application. Which of the following approaches should the developer consider?

Please select all the correct answers that apply.

• Implementing parallel processing (Correct)

• Minimizing the use of internal tables
• Applying appropriate buffering techniques (Correct)
• Using native SQL instead of Open SQL
• Code pushdown to the database layer (Correct)

Explanation
Implementing parallel processing, applying appropriate buffering techniques, and code
pushdown to the database layer are all valid approaches that an ABAP developer can
consider to enhance the performance of a data-intensive application. These approaches
can help reduce database load, improve data retrieval speed, and optimize data
processing logic. However, there are other possible approaches that can also improve
performance, such as:

Database access optimization: This approach involves minimizing database round trips,
using appropriate access methods, restricting the volume of data retrieved, using
aggregate and grouping functions, and avoiding nested or repeated SELECT
statements.

Coding techniques: This approach involves carefully crafting coding practices that can
impact performance, such as using dynamic SQL, using field symbols and references,
using inline declarations, using functional methods, using string templates, and avoiding
unnecessary conversions.

Performance traces and runtime analysis: This approach involves using tools such as
ABAP Trace (SAT), SQL Trace (ST05), SQL Monitor (SQLM), Runtime Analysis (SE30), or
Code Inspector (SCI) to identify and analyze performance bottlenecks, optimize SQL
statements, and check code quality.

Indexing and table partitioning: This approach involves optimizing database indexes
and implementing table partitioning techniques to improve data retrieval and
manipulation speed, especially for large tables.

Memory management: This approach involves managing the memory usage of the
application, avoiding memory leaks, using shared memory objects, and using data
compression techniques.

Question 35: Correct

In a test method, you call the method

cl_abap_unit_assert=>assert_equals( ..) in the following way:

CLASS ltcl1 DEFINITION FOR TESTING RISK LEVEL HARMLESS DURATION SHORT.

PRIVATE SECTION.

METHODS m1 FOR TESTING.

ENDCLASS.

CLASS ltcl1 IMPLEMENTATION.

METHOD m1.

DATA: go_test_object TYPE REF TO zcl_to_be_tested.

CONSTANTS: lco_exp TYPE string VALUE 'test2'.

CREATE OBJECT go_test_object.

cl_abap_unit_assert=>assert_equals(

EXPORTING

act = go_class->mv_attribute
 exp = lco_exp

msg = `assert equals failed ` && go_test_object->mv_attribute && ` ` && lco_exp ).

ENDMETHOD.

ENDCLASS.

What will happen if method parameters act and exp are not equal?

Please choose the correct answer.

• There will be a message in the test log. (Correct)

• The tested unit will automatically be appended to a default ABAP Test Cockpit
Variant.
• The test will be aborted.
• The tested unit cannot be transported.

Explanation
The method cl_abap_unit_assert=>assert_equals is used to check if two objects are
equal in ABAP unit testing. If the objects are not equal, the method will raise a failure
and display the message provided in the msg parameter. In this case, the message will
show the values of go_test_object->mv_attribute and lco_exp, which are the actual and
expected values respectively.

Question 36: Correct

What is the purpose of a Constructor method in Object Oriented ABAP? Please choose
the correct answer.
• To initialize an object when it is created (Correct)
• To clean up resources when an object is deleted
• To perform database updates
• To handle exceptions in object methods

Explanation
The purpose of a Constructor method in Object Oriented ABAP is to initialize an object
when it is created. A Constructor method is a special method that produces a defined
initial state for an object. It is called automatically when an object is created using the
statement CREATE OBJECT. A Constructor method can have importing parameters, but
no exporting parameters. The name of the Constructor method must be
CONSTRUCTOR. So, the purpose of a Constructor method in Object Oriented ABAP is
indeed to initialize an object when it is created.
Question 37: Correct
In ABAP CDS, what is the role of an Association? Please choose the correct answer.
• To manage user roles and permissions
• To optimize database storage
• To link CDS views for data retrieval (Correct)
• To define a connection to external systems

Explanation
In ABAP Core Data Services (CDS), the role of an Association is to link CDS views for
data retrieval. Associations are a part of the CDS syntax used to define the relationship
between two or more entities3. This allows you to easily query, navigate, and access
related data. Associations are kinds of Joins to fetch data from multiple tables on Join
Conditions but these are ‘JOINS ON-DEMAND’ i.e., they will only be triggered when the
user accesses the required data which needs the Association of tables. So, the role of
an Association in ABAP CDS is indeed to link CDS views for data retrieval.

Explanation
Identify the role of the ‘SAP Cloud Application Programming Model’ in ABAP Cloud
development. The SAP Cloud Application Programming Model plays a crucial role in
ABAP Cloud development by providing a comprehensive set of tools and languages for
building cloud-native applications. With this model, developers can easily create and
manage cloud-based applications using a range of programming languages, including
Java, Node.js, and TypeScript. This model also provides a flexible and scalable
framework that makes it easy to integrate with other cloud services and APIs, ensuring
that developers can create powerful and reliable applications quickly and efficiently.
Question 39: Correct
What is the purpose of the 'ENQUEUE' and 'DEQUEUE' functions in ABAP? Please
choose the correct answer.
• To control access to shared resources (Correct)
• To perform asynchronous processing
• To handle file operations
• To manage memory allocation
Explanation
The purpose of the ‘ENQUEUE’ and ‘DEQUEUE’ functions in ABAP is to control access to
shared resources. These functions are used to set and release locks on database
objects, such as tables or records, to prevent data inconsistency and concurrency
issues. The ‘ENQUEUE’ function inserts a lock entry into a lock table, which specifies the
object to be locked, the lock mode, and the lock owner. The ‘DEQUEUE’ function
removes the lock entry from the lock table, which releases the lock on the object. These
functions are automatically generated when a lock object is created in the ABAP
Dictionary. So, the purpose of the ‘ENQUEUE’ and ‘DEQUEUE’ functions in ABAP is
indeed to control access to shared resources.

Question 40: Correct

A developer is designing a data model to represent sales orders and their line items.
Which approach should be used in ABAP CDS for optimal design?

There are 3 correct answers to this question.

• Implement all logic in a single CDS view

• Utilize input parameters to filter data dynamically (Correct)
• Avoid using parameters in CDS views
• Create a CDS view for sales orders and another for line items (Correct)
• Use associations to link sales orders and line items (Correct)

Explanation
Creating a CDS view for sales orders and another for line items, using associations to
link sales orders and line items, and utilizing input parameters to filter data dynamically
are all good practices for designing a data model in ABAP CDS for optimal performance
and flexibility. These practices can help you achieve the following benefits:

Creating a CDS view for sales orders and another for line items allows you to separate
the header and item data, which can have different cardinalities and attributes. This can
improve the readability and maintainability of your data model, as well as reduce the
amount of data transferred from the database.

Using associations to link sales orders and line items allows you to define the
relationships between the CDS views, which can be used to easily query, navigate, and
access related data. Associations are kind of Joins to fetch data from multiple tables
on Join Conditions but these are ‘JOINS ON-DEMAND’ i.e., they will only be triggered
when the user would access the required data which needs the Association of tables.
This can improve the performance and flexibility of your data model, as well as enrich
the semantics of your data elements.

Utilizing input parameters to filter data dynamically allows you to pass values to the
CDS views at runtime, which can be used to restrict the data selection based on certain
criteria. This can improve the performance and flexibility of your data model, as well as
enable the reuse of your CDS views for different scenarios.
