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.)

Comprehensive and Detailed Explanation from Exact Extract:

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.

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.

The correct way to change the contents of a row in an internal table is by using the MODIFY statement.

MODIFY allows updating the existing entry in an internal table based on its key or position.

If the row exists, the statement replaces the data; if not, it inserts a new row depending on the internal table type and whether a key is specified.

INSERT adds new rows but does not modify.

APPEND adds entries at the end, and UPDATE is for database tables, not internal tables.

This behavior is consistent with the ABAP programming model used in both classical and RAP-based developments when manipulating internal collections or buffering data in memory during behavior pool execution.

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.

ABAP Unit Test framework defines a fixed sequence for test fixture methods to ensure reliable test execution and cleanup:

class_setup( ):Called once before any tests in the test class are run. Used to prepare global test data or setup that applies to all tests.

setup( ):Called before each individual test method to prepare local test data or preconditions.

teardown( ):Called after each individual test method to clean up what was done in setup( ).

class_teardown( ):Called once after all tests have been executed to clean up class-level resources.

This sequence supports isolation and repeatability of test executions, ensuring that one test's result does not influence another’s.

ABAP Unit test classes are declared with the addition FOR TESTING in the class definition. RAP test guides also show the same ABAP Unit pattern for local test classes:

CLASS ltcl_sc_r_agency DEFINITION FINAL FOR TESTING

DURATION SHORT

RISK LEVEL HARMLESS.

This is the canonical way to mark an ABAP class as a test class.

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

Comprehensive and Detailed Explanation from Exact Extract:

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.

Comprehensive and Detailed Explanation from Exact Extract:

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.
