Question #11
What are valid statements? Note: There are 3 correct answers to this question
- A . In class CL1, the interface method is named if-ml.
- B . Class CL2 uses the interface.
- C . Class CL1 uses the interface.
- D . In class CL2, the interface method is named ifl-ml.
- E . Class CL1 implements the interface.
Correct Answer: BDE
BDE
Explanation:
The following are the explanations for each statement:
C: This statement is valid. Class CL1 uses the interface. This is because class CL1 implements the interface ifl using the INTERFACES statement in the public section of the class definition. The INTERFACES statement makes the class compatible with the interface and inherits all the components of the interface. The class can then use the interface components, such as the method ml, by using the interface component selector ~, such as ifl~ml12
E: This statement is valid. Class CL1 implements the interface. This is because class CL1 implements the interface ifl using the INTERFACES statement in the public section of the class definition. The INTERFACES statement makes the class compatible with the interface and inherits all the components of the interface. The class must then provide an implementation for the interface method ml in the implementation part of the class, unless the method is declared as optional or abstract12
D: This statement is valid. In class CL2, the interface method is named ifl~ml. This is because class
CL2 has a data member named m0_ifl of type REF TO ifl, which is a reference to the interface ifl. The interface ifl defines a method ml, which can be called using the reference variable m0_ifl. The interface method ml has the name ifl~ml in the class, where ifl is the name of the interface and the character ~ is the interface component selector12
The other statements are not valid, as they have syntax errors or logical errors.
These statements are:
A: This statement is not valid. In class CL1, the interface method is named ifl~ml, not if-ml. This is because class CL1 implements the interface ifl using the INTERFACES statement in the public section of the class definition. The interface ifl defines a method ml, which can be called using the class name or a reference to the class. The interface method ml has the name ifl~ml in the class, where ifl is the name of the interface and the character ~ is the interface component selector. Using the character – instead of the character ~ will cause a syntax error12
B: This statement is not valid. Class CL2 does not use the interface, but only has a reference to the interface. This is because class CL2 has a data member named m0_ifl of type REF TO ifl, which is a reference to the interface ifl. The interface ifl defines a method ml, which can be called using the reference variable m0_ifl. However, class CL2 does not implement the interface ifl, nor does it inherit the interface components. Therefore, class CL2 does not use the interface, but only references the interface12

Question #12
Which internal table type allows unique and non-unique keys?
- A . Sorted
- B . Hashed
- C . Standard
Correct Answer: C
C
Explanation:
The internal table type that allows both unique and non-unique keys is the standard table. A standard table has an internal linear index that can be used to access the table entries. The key of a standard table is always non-unique, which means that the table can contain duplicate entries. However, the system does not check the uniqueness of the key when inserting new entries, so the programmer can ensure that the key is unique by using appropriate logic. A standard table can be accessed either by using the table index or the key, but the response time for key access is proportional to the table size.
The other two internal table types, sorted and hashed, do not allow non-unique keys. A sorted table is filled in sorted order according to the defined table key, which must be unique. A sorted table can be accessed either by using the table index or the key, but the response time for key access is logarithmically proportional to the table size. A hashed table can only be accessed by using a unique key, which must be specified when declaring the table. A hashed table has no index, and the response time for key access is constant, regardless of the table size.

Question #13
In a RESTful Application Programming application, in which objects do you bind a CDS view to create a value help? Note: There are 3 correct answers to this question.
- A . Data model view
- B . Behavior definition
- C . Metadata Extension
- D . Service Definition
- E . Projection View
Correct Answer: A, C, E
A, C, E
Explanation:
In a RESTful Application Programming (RAP) application, you can bind a CDS view to create a value help in the following objects:
Data model view: A data model view is a CDS view that defines the data structure and the associations of an entity in the RAP application. You can use the annotation @Consumption.valueHelpDefinition to bind a value help provider CDS view to an element of the data model view. The value help provider CDS view must contain the key fields of the value help entity and the fields that are displayed in the value help dialog. The value help annotation specifies the entity name, the element name, and optionally the additional binding conditions for the value help provider1.
Metadata Extension: A metadata extension is a CDS view that extends the metadata of another CDS view without changing its data structure. You can use the annotation @MetadataExtension.extendView to specify the target CDS view that you want to extend. You can then use the same annotation @Consumption.valueHelpDefinition to bind a value help provider CDS view to an element of the target CDS view. The metadata extension allows you to add value help definitions to existing CDS views without modifying them2.
Projection View: A projection view is a CDS view that defines the projection of another CDS view. You
can use the annotation @AbapCatalog.sqlViewType: #PROJECTION to specify that the CDS view is a
projection view. You can then use the same annotation @Consumption.valueHelpDefinition to bind a value help provider CDS view to an element of the projection view. The projection view allows you to add value help definitions to projected elements of another CDS view3.
You cannot bind a value help provider CDS view to a behavior definition or a service definition, because these objects do not define the data structure or the metadata of an entity in the RAP application. A behavior definition defines the behavior and the validation rules of an entity, such as the create, read, update, and delete (CRUD) operations, the draft handling, the authorization checks, and the side effects4. A service definition defines the service exposure and the service binding of an entity, such as the protocol, the version, the namespace, and the service name5.

Question #14
What are some features of a unique secondary key? Note: There are 2 correct answers to this question.
- A . It is created when a table is filled.
- B . It is updated when the modified table is read again.
- C . It is created with the first read access of a table.
- D . It is updated when the table is modified.
Correct Answer: CD
CD
Explanation:
A unique secondary key is a type of secondary key that ensures that the key combination of all the rows in a table is unique. A unique secondary key has two purposes: firstly, to speed up access to the table, and secondly, to enforce data integrity1.
It is created with the first read access of a table: This is true. A unique secondary key is created when an internal table is filled for the first time using the statement READ TABLE or a similar statement. The system assigns a name and an index to each row of the table based on the key fields23.
It is updated when the modified table is read again: This is false. A unique secondary key does not need to be updated when the internal table content changes, because it already ensures data uniqueness. The system uses a lazy update strategy for non-unique secondary keys, which means that it delays updating them until they are actually accessed23. You cannot do any of the following:
It is created when a table is filled: This is false. As explained above, a unique secondary key is created only with the first read access of a table23.
It is updated when the modified table is read again: This is false. As explained above, a unique secondary key does not need to be updated when the internal table content changes23.

Question #17
Which of the following ON conditions must you insert in place of "???"?
- A . ON Z_Sourcel.camer_id = 7_Source2 carrier_id
- B . ON Sprojection Camer=Source2 carrier_id
- C . ON Sprojection. Carrier Source2.carrier
- D . ON Sprojection.carrier_id=Z_Source2.carrier_id
Correct Answer: D
D
Explanation:
The correct ON condition that must be inserted in place of “???” is:
ON Sprojection.carrier_id=Z_Source2.carrier_id
This ON condition specifies the join condition between the CDS view Sprojection and the database table Z_Source2. The join condition is based on the field carrier_id, which is the primary key of both the CDS view and the database table. The ON condition ensures that only the records that have the same value for the carrier_id field are joined together1.
The other options are not valid ON conditions, because:

Question #20
Which of the following string functions are predicate functions? Note: There are 2 correct answers to this question.
- A . find_any_not_of()
- B . contains_any_of()
- C . count_any_of()
- D . matchesQ
Correct Answer: B, D
B, D
Explanation:
String functions are expressions that can be used to manipulate character-like data in ABAP. String functions can be either predicate functions or non-predicate functions. Predicate functions are string functions that return a truth value (true or false) for a condition of the argument text. Non-predicate functions are string functions that return a character-like result for an operation on the argument text1.
The following string functions are predicate functions:
B. contains_any_of(): This function returns true if the argument text contains at least one of the characters specified in the character set. For example, the following expression returns true, because the text ‘ABAP’ contains at least one of the characters ‘A’, ‘B’, or ‘C’:
contains_any_of( val = ‘ABAP’ set = ‘ABC’ ).
D. matches(): This function returns true if the argument text matches the pattern specified in the regular expression. For example, the following expression returns true, because the text ‘ABAP’ matches the pattern that consists of four uppercase letters:
matches( val = ‘ABAP’ regex = ‘[A-Z]{4}’ ).
The following string functions are not predicate functions, because they return a character-like result, not a truth value:
