RAP defines the architecture for OData services based on CDS semantic data models and ABAP behavior---this is the current model.

The predecessor is the ABAP Programming Model for SAP Fiori (BOPF/CDS-based), which can be migrated into RAP; it also exposes ABAP backend logic via CDS semantics.

ABAP Cloud Development Model (B) is the rule set/contract (release contracts, checks), not the service-building model. CAP (C) targets Node.js/Java on BTP, not ABAP-based backend services.

Tier 1 (cloud-ready) extensions ''follow ABAP Cloud rules and hence by default can only access the public SAP interfaces (objects released for cloud development).'' This directly supports using released APIs (C) and cloud-enabled/released technologies (D).

The three-tier extensibility model separates safe cloud extensions (Tier 1) from classic code; Tier 2 wrappers exist only to mitigate missing public APIs, but they are not the recommended pattern for S/4HANA Cloud public-edition extensions (therefore B is not a rule).

In S/4HANA Cloud, object changes are not allowed; instead, customers must use predefined extension points (E)---for example, whitelisted extension includes, released BAdIs, or CDS extension points exposed for cloud usage---consistent with the ABAP Cloud principle of public, released artifacts only. (This is the prescribed approach in the ABAP Cloud extensibility guidance that accompanies the three-tier model.)

UI layout is defined with @UI annotations; it is recommended to maintain the UI annotations in metadata extensions to separate concerns and keep CDS clean.

Metadata extensions provide CDS annotations (such as @UI) outside the data definition and allow layered, switchable UI metadata.

In the RAP tutorial, the ''Adding UI Metadata to the Data Model'' section explicitly instructs creating metadata extensions for projection views to control the presentation (line items, identification, hidden fields, search, text arrangement).

Therefore, the RAP artifact used to organize how fields are displayed in the app is the Metadata Extension.

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.

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.

Study Guide Reference: SAP RAP Help -- Business Object Projection Layer.

avg(expr) Allows numeric expressions (e.g., (f1 + f2) / 2).

sum(expr) Accepts numeric expressions.

max() Requires a single column, not expressions.

count(*) Counts rows only, doesn't accept expressions.

Study Guide Reference: ABAP SQL Documentation -- Aggregate Functions.

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.

Study Guide Reference: ABAP CDS User Guide -- CDS View Features and Annotations.

A Recommended to define attributes for message placeholders.

C Inheriting from cx_static_check enforces compile-time checks to ensure exceptions are handled.

E Implementing if_t100_message allows integration with message classes.

B Misleading, design-time warning is about handling, not raising.

D Not a recommended practice in ABAP Cloud (system classes are not extendable).

Study Guide Reference: ABAP Objects Guide -- Defining Exception Classes.

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.

In ABAP Cloud/RAP examples, test classes are created inside the development object (e.g., inside the behavior implementation) and are marked FOR TESTING---these are local classes (they live in the program/class include, not as separate global repository classes). The guides show creating test classes under the Test Classes tab and referencing the Local Types section of the implementation (friends etc.), i.e., local to the program/object.

This contrasts with global classes that exist as standalone repository objects; the RAP test patterns explicitly model the former (local) for unit tests within the object's context.
