Free Practice Questions for SAP C_ABAPD_2507 Exam

Comprehensive and Detailed Explanation From Exact Extract:

Multi-column internal tables are defined using a structured row type, meaning each row is defined by a structure (either defined inline or as a global structure type in the Dictionary).

Option B is correct because it describes how internal tables with multiple fields are built using structured rows.

Option A is incorrect because the row type must be complete and consistent.

Option C is incorrect because nested components are not a requirement.

Option D is misleading. Though “complete data type” may sound correct, it lacks specificity. The correct technical description is that the row type is a structure.

Comprehensive and Detailed Explanation From Exact Extract:

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.

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:

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:

In the ABAP RESTful Application Programming Model (RAP), development follows a bottom-up approach. The sequence starts with the database table (persistence), followed by creating a data model view (interface view), and then a projection view.

The projection view is the next artifact after the database table because it exposes only the fields needed for the app, aligning with the encapsulation principle of RAP. This ensures that only the required subset of the underlying data model is made available.

Comprehensive and Detailed Explanation from Exact Extract:

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).

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:

A watchpoint halts program execution when the content of a specified variable changes.

Exception breakpoints → Trigger when exceptions are raised.

Conditional breakpoints → Stop only if a Boolean condition is true at that line.

Thus, watchpoint is the correct tool for variable-change monitoring.

Comprehensive and Detailed Explanation From Exact Extract:

In SAP S/4HANA Cloud, public edition, database tables are only extendable if SAP has explicitly enabled extensibility for them via metadata. This is a strict limitation in the ABAP Cloud model to ensure upgrade-stability and isolation of extensions from SAP-owned objects.

Key facts:

The annotation @AbapCatalog.dataMaintenance : #RESTRICTED implies that this table is not editable or extensible by default.

The table resides in a delivered component and unless SAP marks it as extensible, customers cannot add fields like zz_countrycode.

Even if the table is in an ABAP Cloud-compliant software component, extensibility must be explicitly enabled by SAP.

Therefore, Option B is the only correct and valid answer.

Incorrect options:

Option A and D are wrong because extensibility is not determined by the software component type alone.

Option C is wrong because customers cannot enable extensibility for SAP-delivered tables; it must be pre-approved by SAP.
