Comprehensive and Detailed Explanation from Exact Extract:

from_mixed converts a mixed-case string into uppercase with a chosen separator between words.

Given input 'LorelpsumFactum', the function splits at uppercase letters, uppercases the parts, and joins them with _.

Output: LORE_IPSUM_FACTUM.

condense only removes extra spaces, to_upper only changes case, and to_mixed does the reverse of from_mixed.

The consumption layer in ABAP CDS views is used to define views for user-facing applications, analytical scenarios, and UI services. The valid view types used at this layer include:

Table Function: Used where custom logic or complex data transformations are required. These are implemented with AMDP or class-based logic and exposed via CDS consumption views.

Analytical Query: Designed for analytical use cases with annotations like @Analytics.query: true to allow exposure to Fiori Analytical apps.

Hierarchy: Used for defining and consuming hierarchical data in CDS. These can be displayed in Fiori Tree tables and analytical contexts.

The following options are incorrect:

Transactional Interface and Transactional Query are not standard view types or part of the CDS view hierarchy used in the consumption layer. These terms may have been incorrectly stated and do not reflect supported CDS artifacts.

Use ABAP Development Tools (ADT) in Eclipse: For ABAP Cloud development, ADT must be used, and modern object types such as CDS View Entities and Behavior Definitions can only be edited in ADT. This confirms option B.

Use SAP-released/predefined extension points: RAP extensibility is opt-in; every possible extension point must be defined explicitly in the original BO artifacts. Extensions are performed only at these predefined points to ensure lifecycle stability—this is exactly the “use SAP-released extension points” rule. This confirms option A.

In contrast, directly modifying SAP objects is not part of the clean-core, upgrade-stable model for public cloud; extensions must adhere to released APIs and predefined points (therefore C is not correct). The classic Web Dynpro UI technology is not the target for ABAP Cloud development in S/4HANA Cloud public edition (therefore D is not correct). (Context anchored by the extensibility/clean-core guidance above.)

Study-Guide anchors: ABAP Cloud development with ADT only; RAP opt-in extensibility and predefined extension points for cloud-ready, upgrade-safe extensions.

Comprehensive and Detailed Explanation from Exact Extract:

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:

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.)

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

Comprehensive and Detailed Explanation From Exact Extract:

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.

Comprehensive and Detailed Explanation From Exact Extract:

OData services are the standard way to expose RAP services; service bindings bind a service definition to a protocol such as OData.

Business events are a released RAP capability for integration; RAP BOs can define, raise, and consume business events, with remote consumption via SAP Event Mesh and event bindings.

CDS views define the semantic data models used for exposure and consumption; ADT defines CDS entities for the data model that can be used in applications. Together, CDS (data modeling) + OData (service exposure) + Events (event-driven integration) constitute the released, recommended integration building blocks in ABAP Cloud/RAP. (BAdIs are classic enhancement spots and not positioned as the primary integration frameworks for ABAP Cloud developer extensibility; SOAP is not the recommended channel in the RAP guidance above.)
