Question No : 1
Which statement creates a reference variable for class CL_VEHICLE?

A.TYPES lo_vehicle TYPE cl_vehicle.
B.DATA lo_vehicle TYPE REF OF cl_vehicle.
C.DATA lo_vehicle LIKE REF cl_vehicle.
D.DATA lo_vehicle TYPE REF TO cl_vehicle.

正解:
Explanation:
In ABAP, object references must be declared with TYPE REF TO <class>.
Option D is correct: DATA lo_vehicle TYPE REF TO cl_vehicle. creates a reference variable.
Option A → Incorrect, TYPES defines a type, not a variable.
Option B → Syntax error, correct keyword is REF TO, not REF OF.
Option C → Invalid, LIKE REF is not supported in ABAP.

Question No : 2
In a RAP business object, where is the validation implementation code contained?

A.Local class
B.Function
C.Global class
D.Subroutine

正解:
Explanation:
In RAP, validations, determinations, and actions are implemented inside the local handler class (lhc_...) of the behavior pool.
Global classes are not used directly for RAP BO logic, only for reusable utilities.
Functions or subroutines are not cloud-compliant for RAP implementation.
Thus, validation code always resides in the local handler class inside the RAP behavior pool.

To which of the following rules must extensions in SAP S/4HANA, public cloud edition adhere? (Select 2 correct answers)

A.Build at the UX layer
B.Use predefined extension points
C.Use CI / CD pipelines
D.Use released APIs

正解:
Explanation:
Extensions in SAP S/4HANA Cloud must follow the ABAP Cloud Extensibility Model.
Use released APIs (D) → Only released and whitelisted APIs are permitted.
Use predefined extension points (B) → Extensions can only be made where SAP has defined extension includes or APIs.
Build at UX layer (A) and Use CI/CD pipelines (C) are good practices but not mandatory extension rules.

Question No : 4
Which of the following are features of Core Data Services (CDS)? (Select 3 correct answers)

A.Associations
B.Delegation
C.Structured Query Language (SQL)
D.Inheritance
E.Annotations

正解:
Explanation:
Associations → Supported in CDS to define relationships between entities without materializing joins.
SQL (Structured Query Language) → CDS is built on SQL semantics and supports declarative data modeling with SQL-based syntax.
Annotations → Used to enrich CDS artifacts with metadata for UI, OData exposure, and behavior.
Delegation → Not a CDS feature; belongs to OO or API design patterns.
Inheritance → Not supported in CDS entities; CDS focuses on associations and compositions.

Question No : 5
Given the following code:
DATA gv_text1 TYPE string. "#EC_NEEDED
DATA gv_text2 TYPE string ##NEEDED.
What are valid statements? (Select 2 correct answers)

A.The pseudo-comment is checked by the syntax checker.
B.The pragma is not checked by the syntax checker.
C.##NEEDED is checked by the syntax checker.
D.#EC_NEEDED is not checked by the syntax checker.

正解:
Explanation:
Pragmas (##) are evaluated by the syntax check and runtime check tools (e.g., ATC, Code Inspector).
##NEEDED is recognized and processed (C).
Pseudo-comments (#EC) are not checked; they are legacy directives to suppress specific findings, hence (D) is correct.
Therefore, A and B are invalid.

Question No : 6
What RAP object contains only the fields required for a particular app?

A.Projection view
B.Metadata extension
C.Database view
D.Data model view

正解:
Explanation:
In RAP, the Projection View is designed to expose only the fields relevant for a specific app, keeping the UI lean and controlled.
Metadata extension → adds UI-related metadata, not fields.
Database view → technical representation, not app-specific.
Data model view → defines the data structure, not app-specific projection.
Verified by RAP documentation: Projection views are application-specific representations of the underlying data model.

Question No : 7
Which statements apply to the TRY-ENDTRY construct? (Select 3 correct answers)

A.A CATCH clause can be used as a handler for several exception classes.
B.A CLEANUP clause catches remaining exceptions.
C.All matching CATCH clauses are always executed.
D.A superclass in a CATCH clause catches exceptions of itself and of its subclasses.
E.CATCH clauses should be organized ascending from most specific to most general.

正解:
Explanation:
A . Valid: A CATCH block can list multiple exception classes separated by |.
B . Wrong: CLEANUP is not a catch mechanism; it executes after try/catch, regardless of exception, but does not handle exceptions.
C . Wrong: Only the first matching CATCH executes, not all.
D . Valid: A superclass exception handler can catch its subclasses.
E. Valid: Best practice is to order CATCH blocks from most specific → most general.

Question No : 8
Given the following Core Data Service View Entity Data Definition:
@AccessControl.authorizationCheck: #NOT_REQUIRED
DEFINE VIEW ENTITY demo_flight_info_union AS
SELECT FROM scustom {
KEY id,
KEY 'Customer' AS partner,
name,
city,
country
}
UNION
SELECT FROM stravelag {
KEY agencynum AS id,
'Agency' AS partner,
name,
city,
country
}
When you attempt to activate the definition, what will be the response?

A.Activation error because the field types of the union do not match
B.Activation error because the key fields of the union do not match
C.Activation successful
D.Activation error because the field names of the union do not match

正解:
Explanation:
In CDS UNION, field names and positions must match exactly across all SELECT statements.
In this case, the first SELECT uses id, while the second uses agencynum AS id, which is fine. However, the literal 'Customer' AS partner and 'Agency' AS partner create inconsistencies.
SAP CDS guidelines specify that for a UNION, field names must be identical and aligned in order; mismatches cause an activation error.

Question No : 9
You have the following CDS definition (aliases shown):
define view entity Z_ENTITY
as select from Z_SOURCE1 as _Source1
association to Z_SOURCE2 as Source2 on ???
{
key carrier_id as Carrier,
key connection_id as Connection,
cityfrom as DepartureCity,
cityto as ArrivalCity,
Source2
}
(The data sources are joined by the field carrier_id. The corresponding field in Z_SOURCE2 is also carrier_id.)
Which ON condition must you insert?

A.ON Z_SOURCE1.carrier_id = Z_SOURCE2.carrier_id
B.ON $projection.carrier_id = Z_SOURCE2.carrier_id
C.ON $projection.Carrier = _Source2.carrier_id
D.ON _Source1.carrier_id = Source2.carrier_id

正解:
Explanation:
In a CDS view entity defined AS SELECT FROM, the association ON condition must use the source aliases defined in the FROM clause.
$projection is used in projection views (AS PROJECTION ON …), not in a basic select view entity.
Therefore, options using $projection (B, C) are invalid here.
Using global names (Z_SOURCE1, Z_SOURCE2) in the ON (A) ignores the declared aliases and is not the recommended/valid form within the view definition.
The correct ON clause uses the aliases _Source1 and Source2 with the matching key fields:
ON _Source1.carrier_id = Source2.carrier_id (D).
This aligns with CDS modeling rules in RAP: use aliases consistently and model associations with precise ON conditions based on keys.

Question No : 10
Which of the following results in faster access to internal tables? (Select 3 correct answers)

A.In a sorted internal table, specifying the primary key completely.
B.In a standard internal table, specifying the primary key partially from the left without gaps.
C.In a sorted internal table, specifying the primary key partially from the left without gaps.
D.In a hashed internal table, specifying the primary key partially from the left without gaps.
E.In a hashed internal table, specifying the primary key completely.

正解:
Explanation:
Sorted tables:
Full key lookup uses a binary search → efficient (A).
Left-aligned partial key lookup also benefits from sort order to find ranges efficiently (C).
Hashed tables:
Require the complete key for O(1) access; partial key is not supported. Hence (E) is correct and (D) is not.
Standard tables:
Have no inherent ordering/index for key-based access; specifying a key (even partially) results in linear search unless you maintain sort and specify BINARY SEARCH explicitly, which still doesn’t change the fundamental case in this question; thus (B) is not considered a faster pattern here.

Question No : 11
Given this code,
INTERFACE if1.
METHODS m1.
ENDINTERFACE.
CLASS cl1 DEFINITION.
PUBLIC SECTION.
INTERFACES if1.
METHODS m2.
ENDCLASS.
" in a method of another class DATA go_if1 TYPE REF TO if1. DATA go_cl1 TYPE REF TO cl1.
go_cl1 = NEW #( ... ).
go_if1 = go_cl1.
What are valid statements? (Select 3 correct answers)

A.Instead of go_cl1 = NEW #( ... ) you could use go_if1 = NEW cl1( ... ).
B.Instead of go_cl1 = NEW #( ... ) you could use go_if1 = NEW #( ... ).
C.go_if1 may call method m2 with go_if1->m2( ... ).
D.go_if1 may call method m1 with go_if1->m1( ... ).
E.go_cl1 may call method m1 with go_cl1->if1~m1( ... ).

正解:
Explanation:
An interface reference (go_if1) can point to any object of a class that implements that interface. Therefore, creating an instance with NEW cl1( … ) and directly assigning it to the interface-typed variable is valid (A).
Type inference with NEW #( … ) cannot infer a class from an interface-typed target (no unique implementing class), so (B) is invalid.
An interface reference exposes only the interface’s methods; it cannot call class-specific methods (so (C) is invalid).
Calling interface method m1 via the interface reference is valid (D).
From the class reference, the interface method can be called (implicitly or explicitly qualified) as go_cl1->if1~m1( … ) (E).
This reflects ABAP OO rules in ABAP Cloud (method visibility via static type, interface implementation, and explicit interface method calls).

B.The documentation has to be positioned directly after the declarative statement.
C.The documentation can contain links to other repository object's documentation.
D.The documentation can be translated.
E.The documentation starts with !.

正解:
Explanation:
ABAP Doc is the integrated documentation system for classes, interfaces, and methods. Rules:
Position → Must be placed directly after the declarative statement (B).
Translatable → ABAP Doc content can be translated (D).
Syntax → Each line must start with ! (E).
HTML tags (A) and repository links (C) are not supported.

Which language is used to add or change data of a business object in RAP?

A.Data manipulation language
B.Entity manipulation language
C.Data modification language
D.RAP editing language

正解:
Explanation:
In RAP, changes to business object data are performed using Entity Manipulation Language (EML).
It provides ABAP statements such as READ ENTITIES, MODIFY ENTITIES, CREATE, and DELETE for RAP BOs.
EML is the cloud-compliant equivalent of SQL DML (insert/update/delete) but tailored to RAP’s transactional consistency.

Which of the following are personas under the SAP S/4HANA Cloud Extensibility Framework? (Select 2 correct answers)

A.Report Writer
B.Business Expert
C.Workflow Administrator
D.Citizen Developer

正解:
Explanation:
SAP S/4HANA Cloud Extensibility Framework defines personas for extension activities:
Business Experts → implement extensions with business knowledge (using in-app extensibility).
Citizen Developers → build extensions with low-code/no-code tools.
Report Writer and Workflow Administrator are roles, but not part of extensibility personas.

Which of the following enforce ABAP Cloud rules? (Select 2 correct answers)

A.ABAP release contracts
B.ABAP platform reuse services
C.ABAP compiler
D.ABAP runtime checks

正解:
Explanation:
ABAP Cloud rules are enforced by:
ABAP Compiler → performs syntax checks against ABAP Cloud rules.
ABAP Runtime Checks → ensure runtime compliance with rules (e.g., avoiding calls to unreleased APIs).
Release contracts and platform reuse services are enablers but do not enforce rules automatically. Verified Study Guide
