SAP C_ABAPD_2507 Online Questions & Answers

• Question 1:

  In what order are objects created to generate a RESTful Application Programming application?

  

  

  Explanation

  Database table

  Data model view

  Projection view

  Service definition

  Service binding

  In RAP, the development flow follows a bottom-up approach , beginning with persistence and ending with OData exposure:

  Database table:The persistence layer where data is stored. This is the foundation of the business object model.

  Data model view (CDS entity):The CDS view is defined on top of the database table to provide a semantic data model. It represents entities like Travel or Booking.

  Projection view:Provides an abstraction of the data model view and controls which fields and associations are exposed externally.

  Service definition:Specifies which projection views (entities) are exposed in the OData service.

  Service binding:Connects the service definition to a communication protocol (e.g., OData V2 or V4), generating the final consumable service endpoint.

  This sequence ensures a layered architecture consistent with RAP guidelines:

  Persistence layer # Data model layer # Projection layer # Service layer # Binding to protocol.

• Question 2:

  What are some features of the current ABAP programming language? (Select 2)

  A. A data object's type can change at runtime.
  B. Keywords are case-sensitive.
  C. The code is expression-based.
  D. It has built-in database access.
  C. The code is expression-based.
  D. It has built-in database access.

  ---

  explanation:

  Explanation

  ABAP for Cloud Development emphasizes expression-oriented, typed programming with strong static checks (e.g., constructor/operators, REDUCE, COND, etc.), which is the modern ABAP style used in RAP. ABAP integrates built-in database access tightly via CDS and Open SQL; CDS entities are the building blocks and govern data access that the runtime executes via the SQL view.

  (A)

  is false (ABAP is statically typed).

  (B)

  is false (ABAP keywords are not case-sensitive).

• Question 3:

  In a booking record, how can you calculate the difference in days between the order date (type D) and the flight date (type D) of a flight?

  A. data(gv_diff_days) = conv d( gs_booking-flight_date - gs_booking-order_date ).
  B. data(gv_diff_days) = gs_booking-flight_date - gs_booking-order_date.
  C. data(gv_diff_days) = gs_booking-order_date - gs_booking-flight_date.
  D. data(gv_diff_days) = conv d( gs_booking-order_date - gs_booking-flight_date ).
  B. data(gv_diff_days) = gs_booking-flight_date - gs_booking-order_date.

  ---

  explanation:

  Explanation

  In ABAP, when calculating the difference between two date fields (type DATS) , the result is directly a type i (integer) representing the difference in days.

  Statement B is correct:

  data(gv_diff_days) = gs_booking-flight_date - gs_booking-order_date.

  This directly subtracts two DATS fields, resulting in an integer value for the number of days difference. No conversion is necessary.

  Statements A and D are incorrect because the conv d( ... ) attempts to convert the result back to a DATS type, which is invalid since the result is an integer (number of days), not a date.

  Statement C is syntactically correct but would produce the negative of the desired value (flight date - order date). It is semantically incorrect for the use case.

  This approach is consistent with ABAP for Cloud Development , which requires explicit typing , and ABAP language version strict mode , where automatic type inference is restricted.

  ABAP Language Documentation ?DATS arithmetic and date operations section; consistent with ABAP Cloud version restrictions.

• Question 4:

  You want to check the behavior of an ordinary class ZCL_ORDINARY with class LTCL_TEST. How do you specify LTCL_TEST as a test class?

  A. Use the addition FOR TESTING in the class declaration of LTCL_TEST.
  B. Create a parameter in the SETUP method of LTCL_TEST and set its value to "Test".
  C. Use the addition FOR TESTING: LTCL_TEST in the class declaration of ZCL_ORDINARY.
  D. Create LTCL_TEST in a special package that is reserved for test classes.
  A. Use the addition FOR TESTING in the class declaration of LTCL_TEST.

  ---

  explanation:

  Explanation

  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.

• Question 5:

  How can you execute test classes? (Select 3)

  A. As a mass test when executing an ABAP Test Cockpit (ATC) check variant.
  B. As a mass test when releasing a transport request with the ABAP Transport Organizer.
  C. Interactively by calling function "Run as a unit test" from within the tested object.
  D. Interactively by calling function "Run as a unit test" from within the test class.
  E. Interactively during the release of transport request.
  A. As a mass test when executing an ABAP Test Cockpit (ATC) check variant.
  C. Interactively by calling function "Run as a unit test" from within the tested object.
  D. Interactively by calling function "Run as a unit test" from within the test class.

  ---

  explanation:

  Explanation

  Interactive runs from the tested object or its test class in ADT: In RAP/ABAP Cloud test guides, you specify a test relation , which then lets you run unit tests directly from the context menu of the behavior definition (tested object) in ADT . This is the "Run as unit test" interaction from the tested object.

  Interactive runs from the test class itself: Test classes are declared with FOR TESTING , and the same RAP guides show the canonical test-class structure used for ABAP Unit . In ADT, you can execute the test class via its context menu ("Run as Unit Test").

  Mass execution with ATC: The same document set prescribes governance via ABAP Test Cockpit (ATC) check variants applied across many objects, supporting mass test/check execution . ATC is used broadly to enforce ABAP Cloud rules and quality gates across developments, which covers running checks/tests at scale (mass).

  There is no built-in mechanism to execute unit tests during transport release ; the recommended mass execution path is via ATC , not via the Transport Organizer. (Hence B and E are not correct.)

• Question 6:

  How do you make class sub1 a subclass of class super1?

  A. In super1 use clause "sub1 REDEFINITION" in the DEFINITION part.
  B. In sub1 use clause "INHERITING FROM super1" in the IMPLEMENTATION part.
  C. In sub1 use clause "INHERITING FROM super1" in the DEFINITION part.
  D. In super1 use clause "sub1 REDEFINITION" in the IMPLEMENTATION part.
  C. In sub1 use clause "INHERITING FROM super1" in the DEFINITION part.

  ---

  explanation:

  Explanation

  In ABAP, inheritance is declared in the class DEFINITION using the keyword INHERITING FROM. The RAP documentation shows this exact syntax in multiple class definitions, for example:

  "CLASS lcl_local_event_consumption DEFINITION INHERITING FROM cl_abap_behavior_event_handler." This proves the inheritance clause belongs to the DEFINITION section, not the IMPLEMENTATION, and uses the form INHERITING FROM .(Back- End Developer ?ABAP Cloud study areas: RAP handler/event classes use standard ABAP OO rules; architecture shows inheritance declared in DEFINITION with INHERITING FROM.)

• Question 7:

  Which of the following results in faster access to internal tables? (Select 3 correct answers)

  A. In a sorted internal table, specifying the primary key completely .
  B. In a standard internal table, specifying the primary key partially from the left without gaps .
  C. In a sorted internal table, specifying the primary key partially from the left without gaps .
  D. In a hashed internal table, specifying the primary key partially from the left without gaps .
  E. In a hashed internal table, specifying the primary key completely .
  A. In a sorted internal table, specifying the primary key completely .
  C. In a sorted internal table, specifying the primary key partially from the left without gaps .
  E. In a hashed internal table, specifying the primary key completely .

  ---

  explanation:

  Explanation

  Sorted tables:

  Full key lookup uses a binary search # efficient (A).

  Left-aligned partial key lookup also benefits from sort order to find ranges efficiently (C).

  Hashed tables:

  Require the complete key for O(1) access; partial key is not supported. Hence (E) is correct and (D) is not.

  Standard tables:

  Have no inherent ordering/index for key-based access; specifying a key (even partially) results in linear search unless you maintain sort and specify BINARY SEARCH explicitly, which still doesn't change the fundamental case in this question;

  thus (B) is not considered a faster pattern here.

• Question 8:

  Which statements apply to the TRY-ENDTRY construct? (Select 3 correct answers)

  A. A CATCH clause can be used as a handler for several exception classes.
  B. A CLEANUP clause catches remaining exceptions.
  C. All matching CATCH clauses are always executed.
  D. A superclass in a CATCH clause catches exceptions of itself and of its subclasses.
  E. CATCH clauses should be organized ascending from most specific to most general.
  A. A CATCH clause can be used as a handler for several exception classes.
  D. A superclass in a CATCH clause catches exceptions of itself and of its subclasses.
  E. CATCH clauses should be organized ascending from most specific to most general.

  ---

  explanation:

  Explanation

  A-. Valid: A CATCH block can list multiple exception classes separated by |.

  B-. Wrong: CLEANUP is not a catch mechanism; it executes after try/catch, regardless of exception, but does not handle exceptions.

  C-. Wrong: Only the first matching CATCH executes, not all.

  D-. Valid: A superclass exception handler can catch its subclasses.

  E-. Valid: Best practice is to order CATCH blocks from most specific # most general.

• Question 9:

  Given this code,

  INTERFACE if1. METHODS m1. ENDINTERFACE.

  CLASS cl1 DEFINITION.

  PUBLIC SECTION.

  INTERFACES if1. METHODS m2. ENDCLASS.

  " in a method of another class

  DATA go_if1 TYPE REF TO if1. DATA go_cl1 TYPE REF TO cl1. go_cl1 = NEW #( ... ).

  go_if1 = go_cl1. What are valid statements? (Select 3 correct answers)

  A. Instead of go_cl1 = NEW #( ... ) you could use go_if1 = NEW cl1( ... ).
  B. Instead of go_cl1 = NEW #( ... ) you could use go_if1 = NEW #( ... ).
  C. go_if1 may call method m2 with go_if1->m2( ... ).
  D. go_if1 may call method m1 with go_if1->m1( ... ).
  E. go_cl1 may call method m1 with go_cl1->if1~m1( ... ).
  A. Instead of go_cl1 = NEW #( ... ) you could use go_if1 = NEW cl1( ... ).
  D. go_if1 may call method m1 with go_if1->m1( ... ).
  E. go_cl1 may call method m1 with go_cl1->if1~m1( ... ).

  ---

  explanation:

  Explanation

  An interface reference (go_if1) can point to any object of a class that implements that interface. Therefore, creating an instance with NEW cl1( ... ) and directly assigning it to the interface-typed variable is valid (A).

  Type inference with NEW #( ... ) cannot infer a class from an interface-typed target (no unique implementing class), so (B) is invalid.

  An interface reference exposes only the interface's methods ; it cannot call class-specific methods (so (C) is invalid).

  Calling interface method m1 via the interface reference is valid (D).

  From the class reference, the interface method can be called (implicitly or explicitly qualified) as go_cl1->if1~m1( ... ) (E).

  This reflects ABAP OO rules in ABAP Cloud (method visibility via static type, interface implementation, and explicit interface method calls).

• Question 10:

  Which of the following types of Core Data Services Views can be used at the consumption layer? Note: There are 3 correct answers to this question.

  A. Table Function
  B. Transactional Interface
  C. Transactional Query
  D. Analytical Query
  E. Hierarchy
  A. Table Function
  D. Analytical Query
  E. Hierarchy

  ---

  explanation:

  Explanation

  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.
