C_ABAPD_2507 Exam Dumps and Practice Questions

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.

In ABAP CDS access controls, the technique used is inheritance, which allows one access control object to reuse rules defined in another.

This makes authorization definitions consistent, reusable, and maintainable, which is essential in RAP applications where business objects require layered and reusable authorization concepts.

Options such as Redefinition, Singleton, or Casting belong to OO concepts, not to access control in CDS.

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.

The purpose of a foreign key relationship in the ABAP Dictionary is to ensure the integrity of data between the related database tables. This relationship checks that values entered in the foreign key field exist in the check table, thereby preventing invalid or orphaned entries.

While foreign key relationships do not automatically enforce constraints at the database level, they are used for enforcing referential integrity at the application layer and play a key role in:

Input help (F4 Help)

Validation checks during data modification

Ensuring consistency of master and transaction data

This aligns with the standard ABAP development model, where the application layer (not the database) handles logical consistency using metadata from the ABAP Dictionary.

SAP recommends using CDS view entities over classic CDS DDIC-based views due to the following benefits:

Simpler and stricter syntax: CDS view entities enforce a clearer separation of concerns and reduce ambiguity, which helps ensure consistency across the stack. This makes Option C correct.

Elimination of the need for a database view: With CDS view entities, there's no dependency on a separate DDIC SQL view object, reducing redundancy and improving activation performance. This makes Option D correct.

Incorrect options:

Automated client handling (Option A) is supported in both CDS view entities and classic CDS views via annotations like @ClientHandling.

Simplified syntax check (Option B) is not a distinct feature of CDS view entities. Syntax checking is part of ABAP Development Tools regardless of the CDS flavor used.
