When defining a METHOD, which parameter type can only have 1 value?
D
Explanation:
In ABAP Object-Oriented Programming within ABAP Cloud, methods can define multiple parameters
of type IMPORTING, EXPORTING, or CHANGING. However, for RETURNING parameters, only one
value is permitted per method.
This restriction ensures that RAP BOs and ABAP Cloud classes expose methods with clear,
unambiguous outputs, aligning with best practices of encapsulation and functional programming
design.
IMPORTING → multiple allowed
EXPORTING → multiple allowed
CHANGING → multiple allowed
RETURNING → exactly one allowed

In a class you use the statement DATA var TYPE …
What may stand in place of the type?
(Select 2 correct answers)
A, D
Explanation:
The ABAP DATA statement declares a variable with an assigned type.
A . Private type in the same class (ZCL_CLASS_A) → Allowed. A class can use its own local type
definitions, declared using TYPES.
B . Domain from ABAP Dictionary → Not allowed directly. Domains define technical attributes but
cannot be referenced directly in DATA; they must be wrapped in a data element.
C . Type defined privately in another class → Not accessible, since private definitions are
encapsulated.
D . Data element from ABAP Dictionary → Allowed, because data elements are global dictionary
objects.
This follows ABAP Cloud extensibility rules, ensuring encapsulation and strict typing.

After you created a database table in the RESTful Application Programming model, what do you
create next?
D
Explanation:
In the ABAP RESTful Application Programming Model (RAP), development follows a bottom-up
approach. The sequence starts with the database table (persistence), followed by creating a data
model view (interface view), and then a projection view.
The projection view is the next artifact after the database table because it exposes only the fields
needed for the app, aligning with the encapsulation principle of RAP. This ensures that only the
required subset of the underlying data model is made available.

Views.
What are some principles of encapsulation?
(Select 2 correct answers)
A, D
Explanation:
Encapsulation in ABAP OO and ABAP Cloud ensures that internal object details are hidden from
outside consumers.
A . Attributes can be changed through public methods → Correct, because controlled access is
provided through getter/setter or other methods.
B . Attributes can be changed by the client program directly → Incorrect, this violates encapsulation.
C . Attributes cannot be changed → Incorrect, they can be changed, but only via allowed
mechanisms.
D . Attributes can only be changed by the class itself → Correct, ensuring business logic consistency.
This aligns with RAP behavior definitions (BDEF) where internal attributes are encapsulated and only
manipulated through behavior implementation methods.

Given the following ABAP code, which exception will be raised on execution?
CONSTANTS c_char TYPE c LENGTH 1 VALUE ' '.
TRY.
result = 2 / c_char.
out->write( |Result: { result }| ).
CATCH cx_sy_zerodivide.
out->write( |Error: Division by zero is not defined| ).
CATCH cx_sy_conversion_no_number.
out->write( |Error: { c_char } is not a number!| ).
CATCH cx_sy_itab_line_not_found.
out->write( |Error: Itab contains less than { 2 / c_char } rows| ).
ENDTRY.
B
Explanation:
Here, c_char is defined as a character type with a space ' ' as its value.
When attempting 2 / c_char, ABAP tries to interpret the character ' ' as a number. Since it is not a
numeric value, ABAP raises the conversion error cx_sy_conversion_no_number.
cx_sy_zerodivide would occur only if the denominator was zero numeric.
cx_sy_itab_line_not_found applies to internal table access errors, not relevant here.
This is consistent with ABAP Cloud runtime exception handling, where strict typing and error
categories are clearly defined.

DATA: regex TYPE string VALUE '[0-9]{4}(-[0-9]{2})(2}'.
In which of the following functions can you use regular expressions?
(Select 3 correct answers)
B, D, E
Explanation:
In ABAP Cloud, string functions that support regular expressions (PCRE) include:
match( ) → returns the first substring matching the regex.
matches( ) → checks if the whole string matches the regex.
find( ) → finds a substring based on regex pattern.
Functions such as reverse( ) and condense( ) do not support regex patterns; they are purely string
manipulation utilities.

Expressions.
Which of the following custom code use cases falls under Tier 1 extensibility guidelines?
B
Explanation:
Tier 1 extensibility in ABAP Cloud corresponds to the safe and upgrade-stable extension layer.
Adding custom fields to released DB tables or CDS views via released extension includes is fully
supported.
Using classic user exits (A), manual note corrections (C), or wrappers for unreleased APIs (D) belong
to Tier 2 or Tier 3, and are not part of Tier 1 safe extensibility.
This guarantees that custom code in Tier 1 is cloud-ready, upgrade-stable, and based only on
released extension points and APIs.

How can you control data access of a business user?
(Select 3 correct answers)
B, C, D
Explanation:
In ABAP Cloud / RAP, authorization control follows a structured approach:
Read access → can be controlled implicitly via an Access Control object (D).
Create, Update, Delete access → can be controlled both:
Explicitly with AUTHORITY-CHECK (B),
Or implicitly through Access Control object definitions (C).
General implicit control via Access Control (A) or explicit checks for Read (E) are not correct because
the system differentiates access levels precisely.
This ensures that business users can only access the data they are authorized for, following RAP’s
security-by-default principle.
Verified Study Guide Reference: RAP Security & Access Control Documentation – Authorization in
RAP BOs.
Which of the following is a technique for defining access controls?
A
Explanation:
In ABAP CDS access controls, the technique used is inheritance, which allows one access control
object to reuse rules defined in another.
This makes authorization definitions consistent, reusable, and maintainable, which is essential in RAP
applications where business objects require layered and reusable authorization concepts.
Options such as Redefinition, Singleton, or Casting belong to OO concepts, not to access control in
CDS.

In CDS views, what do joins and associations have in common?
(Select 2 correct answers)
A, C
Explanation:
In CDS views:
A . Aliases → Allowed for data sources and their fields, both in joins and associations.
C . ON clause → Both joins and associations use ON conditions to link data sources.
B . Expose entire data source without fields → Incorrect; explicit field selection is required.
D . Field list without data source prefix → Incorrect; unless aliased, fields must be qualified.
Thus, the overlap between joins and associations lies in aliasing and ON clause usage.

You want to define the following CDS view entity with an input parameter:
define view entity Z_CONVERT
with parameters i_currency : ???
Which of the following can you use to replace ????
(Select 2 correct answers)
A, D
Explanation:
CDS view parameters must be defined with types that are visible in the ABAP Dictionary.
A . Built-in ABAP Dictionary type → Supported (e.g., CURR, CHAR).
D . Data element → Supported, as data elements are dictionary-level types.
B . Built-in ABAP type (like i, string) → Not supported directly, CDS requires dictionary-compatible
types.
C . Component of a structure → Not supported directly; parameters cannot reference structure
components.
This ensures that CDS definitions remain database-compatible and semantically rich, which is critical
for RAP services.

Which internal table type allows unique and non-unique keys?
B
Explanation:
Sorted tables can be declared with unique keys (ensuring no duplicates) or with non-unique keys
(allowing duplicates).
Hashed tables only allow unique keys.
Standard tables allow non-unique keys only.
Thus, sorted internal tables are the only type that can be configured with both unique and non-
unique keys.

Constructors have which of the following properties?
(Select 2 correct answers)
A, B
Explanation:
A . Automatic execution → A constructor (CONSTRUCTOR) is automatically invoked when an
instance of a class is created.
B . Importing parameters → Constructors can have importing parameters to initialize the object with
values.
C . First method called by client → Not correct, because constructors are called by the system, not
the client explicitly.
D . Returning parameters → Constructors cannot return values; they only set up the object.
This behavior is consistent across ABAP Cloud OOP classes, ensuring encapsulated initialization logic.

Which of the following Core Data Services built-in functions returns a result of type INT4?
(Select 2 correct answers)
C, D
Explanation:
dats_add_days → Returns the number of days added/subtracted to a given date → INT4.
dats_days_between → Returns the number of days between two dates → INT4.
dats_add_months → Returns a DATE, not INT4.
dats_is_valid → Returns a BOOLEAN (flag), not INT4.
In CDS, these date functions are used for calculations in queries, supporting business logic
pushdown.

You have a superclass super1 and a subclass sub1 of super1. Each class has an instance constructor
and a static constructor. The first statement of your program creates an instance of sub1.
In which sequence will the constructors be executed?
B
Explanation:
Execution order when creating an instance of a subclass:
Class constructor of the superclass (super1) executes first.
Class constructor of the subclass (sub1) executes second.
Then the instance constructor of the superclass (super1) executes.
Finally, the instance constructor of the subclass (sub1) executes.
This sequence guarantees that both the static (class-level) and instance-level initializations of the
superclass are complete before the subclass is constructed.
