Question #21
Which of the following integration frameworks have been released for ABAP cloud development? Note: There are 3 correct answers to this question.
- A . SOAP consumption
- B . CDS Views
- C . Business Add-ins (BAdls)
- D . Business Events
- E . OData services
Correct Answer: A, D, E
A, D, E
Explanation:
The following are the integration frameworks that have been released for ABAP cloud development: SOAP consumption: This framework allows you to consume SOAP web services from ABAP cloud applications. You can use the ABAP Development Tools in Eclipse to create a service consumption model based on a WSDL file or URL. The service consumption model generates the required ABAP artifacts, such as proxy classes, data types, and constants, to access the web service. You can then use the proxy classes to call the web service operations from your ABAP code1
Business Events: This framework allows you to publish and subscribe to business events from ABAP cloud applications. Business events are messages that represent a change in the state of a business object or process. You can use the ABAP Development Tools in Eclipse to create a business event definition based on a CDS view entity or a projection view. The business event definition specifies the event key, the event payload, and the event metadata. You can then use the ABAP Messaging Channel (AMC) framework to publish and subscribe to business events using the AMC API2
OData services: This framework allows you to expose and consume OData services from ABAP cloud applications. OData is a standardized protocol for creating and consuming RESTful APIs. You can use the ABAP RESTful Application Programming Model (RAP) to create OData services based on CDS view entities or projection views. The RAP framework generates the required OData metadata and runtime artifacts, such as service definitions, service bindings, and service implementations. You can then use the SAP Gateway framework to register and activate your OData services. You can also use the ABAP Development Tools in Eclipse to consume OData services from other sources using the service consumption model3
The other integration frameworks are not released for ABAP cloud development, as they are either not supported or not recommended for cloud scenarios.
These frameworks are:
CDS Views: CDS views are not an integration framework, but a data modeling framework. CDS views are used to define data models based on database tables or other CDS view entities. CDS views can have associations, aggregations, filters, parameters, and annotations. CDS views can also be used as the basis for other integration frameworks, such as OData services or business events4
Business Add-ins (BAdls): BAdls are not supported for ABAP cloud development, as they are part of the classic ABAP enhancement framework. BAdls are used to implement custom logic in predefined enhancement spots in the standard SAP code. BAdls are not compatible with the cloud strategy and the clean core paradigm, as they modify the SAP code and can cause upgrade and maintenance issues. For ABAP cloud development, SAP recommends using the key user extensibility tools or the side-by-side extensibility approach instead of BAdls.

Question #25
Refer to Exhibit.
When accessing the subclass instance through go_super, what can you do? Note: There are 2 correct answers to this question.
- A . Access the inherited private components.
- B . Access the inherited public components.
- C . Call a subclass specific public method
- D . Call inherited public redefined methods.
Correct Answer: BD
BD
Explanation:
In object-oriented programming (OOP), particularly in ABAP OOP, when you have a reference to a superclass and you’re working with an instance of a subclass, here’s what you can do:
Access the inherited public components – This is correct. You can always access public components of the superclass through a reference to the superclass, even if the actual object is an instance of a subclass.
Call inherited public redefined methods – This is also correct. If the subclass has redefined a method that was public in the superclass, and you call this method through a reference of the superclass type, the redefined version in the subclass will be executed. This is known as polymorphism.

Question #28
Exhibit:
What are valid statements? Note: There are 3 correct answers to this question.
- A . go_if 1 may call method ml with go_ift->ml().
- B . Instead of go ell = NEW #(…) you could use go ifl = NEW cll(. … ).
- C . go_cll may call method ml with go_dl->ifl-ml().
- D . Instead of go_cll = NEW #() you could use go_iff – NEW #(…).
- E . go_ifl may call method m2 with go if->m2(…).
Correct Answer: ABE
ABE
Explanation:
Based on the exhibit and standard ABAP object-oriented programming concepts, let’s evaluate each statement:
go_if1 may call method m1 with go_if1->m1(). – This is correct. go_if1 is typed as a reference to interface if1, which contains the method m1. Hence, go_if1 can be used to call m1.
Instead of go_cl1 = NEW #(…), you could use go_if1 = NEW cl1(…). – This is correct. Since cl1 implements interface if1, you can create an instance of cl1 and assign it to a variable typed with the interface if1.
go_cl1 may call method m1 with go_cl1->if1~m1(). – This is correct. The syntax go_cl1->if1~m1() is used to call an interface method implemented by a class in ABAP, and since cl1 implements if1, which has method m1, this is valid.
