Comprehensive and Detailed Explanation from Exact Extract:

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.

In ABAP Cloud, translation is supported for:

Data element texts (short, medium, long descriptions).

Message class texts (used in MESSAGE statements).

Text symbols (defined in programs).

Not translatable:

String variables → runtime values, no translation.

Text literals → hard-coded, not translatable via translation tools.

Comprehensive and Detailed Explanation from Exact Extract:

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.

Study Guide Reference: ABAP Objects Programming Guide – Reference Variable Declarations.

Comprehensive and Detailed Explanation from Exact Extract:

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.

Comprehensive and Detailed Explanation From Exact Extract:

CDS View Entities are the successor of classic DDIC-based CDS views and do not use the CDS-managed DDIC view; therefore @AbapCatalog.sqlViewName (used for classic DDIC-based views) is not required for view entities. This eliminates option B.

RAP and CDS modeling rely on key fields identified by the keyword key in the underlying CDS view to uniquely identify instances; this key is fundamental for BOs and their sources. A view entity without any key elements therefore lacks a primary key and will not pass activation. This supports option A.

Authorization annotations are component annotations; their absence does not by itself block first-time activation of a CDS entity. This rules out option D as the primary cause.

Study-Guide anchors: CDS View Entities (successor of DDIC-based views; no SQL view name), requirement for key elements to define primary keys, and activation behavior for component annotations.

Comprehensive and Detailed Explanation From Exact Extract:

ABAP Open SQL allows CAST( … AS … ) to SQL/Dictionary-compatible types such as CHAR(n) and DEC(p,s), which are valid (A, D).

ABAP numeric integer target is accepted as I in Open SQL casting context on recent ABAP platform levels (E).

N(8) is not a valid SQL cast target (NUMC is an ABAP elementary type, not an SQL cast target), and plain INT8 (without the ABAP type namespace form) is not a generally valid SQL type literal in Open SQL (so B and C are rejected on standard ABAP Cloud systems).

RAP and ABAP Cloud emphasize pushdown with typed SQL expressions and strict static checks; only released, database-compatible types are permitted in CAST, enforced by the language and static checks.

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.

Comprehensive and Detailed Explanation from Exact Extract:

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.

Comprehensive and Detailed Explanation From Exact Extract:

The EXTRACT_YEAR, EXTRACT_MONTH, and EXTRACT_DAY functions in ABAP SQL are SQL built-in functions used for extracting date components. These functions are only supported for timestamp-capable or date-capable fields.

According to the ABAP CDS Development Guide and SAP HANA SQL capabilities available to ABAP SQL via CDS or native SQL:

DATS (ABAP Dictionary data type for dates) is fully supported for extract functions.

TIMESTAMP and UTCLONG are also supported since they represent full date-time values and are mapped internally to TIMESTAMP with time zone considerations.

TIMS is a time-only type and is not valid for extract date functions.

TIMN is for time periods and is also not valid for extracting year, month, or day.

Therefore:

Option B (UTCLONG) – correct

Option C (TIMESTAMP) – correct

Option D (DATS) – correct

Options A (TIMS) and E (TIMN) – incorrect
