NEW QUESTION # 17
Which type of legacy code does SAP recommend you eliminate when you review modifications as part of an SAP S/4HANA system conversion? Note: There are 2 correct answers to this question.
- A. Code that now is identical to a standard SAP object
- B. Code that supports a critical business process
- C. Code that has less than 10% usage according to usage statistics
- D. Code that can be redesigned as a key user extension
Answer: A,D
Explanation:
SAP recommends that you eliminate the following types of legacy code when you review modifications as part of an SAP S/4HANA system conversion:
Code that now is identical to a standard SAP object. This type of code is redundant and unnecessary, as it does not provide any additional functionality or customization. It can also cause conflicts or errors during the system conversion, as the standard SAP object may have changed or been replaced in SAP S/4HANA. Therefore, you should delete this type of code and use the standard SAP object instead.
Code that can be redesigned as a key user extension. This type of code is usually related to UI or business logic adaptations that can be achieved using the in-app tools provided by SAP S/4HANA. By redesigning this type of code as a key user extension, you can simplify and standardize your code base, reduce maintenance efforts, and avoid compatibility issues during the system conversion. Therefore, you should migrate this type of code to the key user extensibility framework and delete the original code.
The other types of legacy code are not recommended to be eliminated, as they may still be relevant or necessary for your business processes. However, you should still review and adjust them according to the SAP S/4HANA simplification items and best practices. These types of code are:
Code that supports a critical business process. This type of code is essential for your business operations and cannot be easily replaced or removed. However, you should check if this type of code is compatible with SAP S/4HANA, and if not, you should adapt it accordingly. You should also consider if this type of code can be optimized or enhanced using the new features and capabilities of SAP S/4HANA.
Code that has less than 10% usage according to usage statistics. This type of code is rarely used and may not be worth maintaining or converting. However, you should not delete this type of code without verifying its relevance and impact on your business processes. You should also consider if this type of code can be replaced or consolidated with other code that has higher usage or better performance.
NEW QUESTION # 18
While debugging an ABAP program, you want the program to stop whenever the value of a variable changes.
Which of the following do you use?
- A. Conditional breakpoint
- B. Exception breakpoint
- C. Watchpoint
Answer: C
Explanation:
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.
Study Guide Reference: ABAP Debugging Guide - Breakpoints and Watchpoints.
NEW QUESTION # 19
In what order are objects created to generate a RESTful Application Programming application?
Answer:
Explanation:
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.
Reference: SAP Help 1, pages 4-6 - RAP design time development flow (data modeling, business service provisioning, service consumption).
NEW QUESTION # 20
What is the purpose of a foreign key relationship between two tables in the ABAP Dictionary?
- A. To create a corresponding foreign key relationship in the database
- B. None of the above
- C. To document the relationship between the two tables
- D. To ensure the integrity of data in the corresponding database tables
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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.
Reference: SAP Help 1, page 6 - Explains how data consistency is handled through metadata definitions including foreign key relationships as part of data modeling and behavior layer.
NEW QUESTION # 21
What are some features of the current ABAP programming language? Note: There are 2 correct answers to this question.
- A. A data object's type can change at runtime.
- B. It has built-in database access.
- C. Keywords are case-sensitive.
- D. The code is expression-based.
Answer: B,D
NEW QUESTION # 22
Which of the following is a technique for defining access controls?
- A. Inheritance
- B. Casting
- C. Redefinition
- D. Singleton
Answer: A
Explanation:
Comprehensive and Detailed Explanation from Exact Extract:
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.

Answer: B,C,E
NEW QUESTION # 26
In a subclass subl you want to redefine a component of a superclass superl. How do you achieve this? Note: There are 2 correct answers to this question.
- A. You add the clause REDEFINITION to the component in subl.
- B. You add the clause REDEFINITION to the component in superl.
- C. You implement the redefined component in subl.
- D. You implement the redefined component for a second time in superl.
Answer: A,C
Explanation:
To redefine a component of a superclass in a subclass, you need to do the following12:
You add the clause REDEFINITION to the component declaration in the subclass. This indicates that the component is inherited from the superclass and needs to be reimplemented in the subclass. The redefinition must happen in the same visibility section as the component declaration in the superclass. For example, if the superclass has a public method m1, the subclass must also declare the redefined method m1 as public with the REDEFINITION clause.
You implement the redefined component in the subclass. This means that you provide the new logic or behavior for the component that is specific to the subclass. The redefined component in the subclass will override the original component in the superclass when the subclass object is used. For example, if the superclass has a method m1 that returns 'Hello', the subclass can redefine the method m1 to return 'Hi' instead.
You cannot do any of the following:
You implement the redefined component for a second time in the superclass. This is not possible, because the superclass already has an implementation for the component that is inherited by the subclass. The subclass is responsible for providing the new implementation for the redefined component, not the superclass.
You add the clause REDEFINITION to the component in the superclass. This is not necessary, because the superclass does not need to indicate that the component can be redefined by the subclass. The subclass is the one that needs to indicate that the component is redefined by adding the REDEFINITION clause to the component declaration in the subclass.
NEW QUESTION # 27

Answer: A,B
NEW QUESTION # 28
What RESTful Application Programming feature is used to ensure the uniqueness of a semantic key?
- A. Determination
- B. Action
- C. Validation
Answer: A
Explanation:
The RESTful Application Programming feature that is used to ensure the uniqueness of a semantic key is determination. A determination is a type of behavior implementation that defines a logic that is executed automatically when certain events occur, such as create, update, delete, or activate. A determination can be used to calculate or derive values for certain fields, such as semantic keys, based on other fields or external sources. A determination can also be used to check the uniqueness of a semantic key by comparing it with the existing values in the database or the transaction buffer. A determination can use the ABAP SQL or the EML syntax to access and manipulate data. A determination can be defined using the DETERMINE action clause in the behavior definition of a CDS view entity or a projection view. A determination can also be annotated with the @ObjectModel.determination annotation to specify the event, the timing, and the scope of the determination12 The other RESTful Application Programming features are not used to ensure the uniqueness of a semantic key, but have different purposes and effects. These features are:
Validation: A validation is a type of behavior implementation that defines a logic that is executed automatically when certain events occur, such as create, update, delete, or activate. A validation can be used to check the consistency and correctness of the data, such as mandatory fields, data types, value ranges, or business rules. A validation can use the ABAP SQL or the EML syntax to access and manipulate data. A validation can be defined using the VALIDATE action clause in the behavior definition of a CDS view entity or a projection view. A validation can also be annotated with the @ObjectModel.validation annotation to specify the event, the timing, and the scope of the validation12 Action: An action is a type of behavior implementation that defines a logic that is executed explicitly by the user or the application. An action can be used to perform a specific business operation, such as creating, updating, deleting, or activating an entity instance, or triggering a workflow or a notification. An action can use the ABAP SQL or the EML syntax to access and manipulate data. An action can be defined using the ACTION clause in the behavior definition of a CDS view entity or a projection view. An action can also be annotated with the @ObjectModel.action annotation to specify the name, the description, the parameters, and the visibility of the action12
NEW QUESTION # 29
Refer to the exhibit.
with which predicate condition can you ensure that the CAST will work?
- A. IS INSTANCE OF
- B. IS NOT INITIAL
- C. IS SUPPLIED
- D. IS BOUND
Answer: A
Explanation:
The predicate condition that can be used to ensure that the CAST will work is IS INSTANCE OF. The IS INSTANCE OF predicate condition checks whether the operand is an instance of the specified class or interface. This is useful when you want to perform a downcast, which is a conversion from a more general type to a more specific type. A downcast can fail if the operand is not an instance of the target type, and this can cause a runtime error. Therefore, you can use the IS INSTANCE OF predicate condition to check whether the downcast is possible before using the CAST operator12. For example:
The following code snippet uses the IS INSTANCE OF predicate condition to check whether the variable g_super is an instance of the class lcl_super. If it is, the CAST will work and the variable g_sub1 will be assigned the value of g_super.
DATA: g_super TYPE REF TO lcl_super, g_sub1 TYPE REF TO lcl_sub1. IF g_super IS INSTANCE OF lcl_super. g_sub1 = CAST #( g_super ). g_sub1->method( ... ). ENDIF.
You cannot do any of the following:
IS SUPPLIED: The IS SUPPLIED predicate condition checks whether an optional parameter of a method or a function module has been supplied by the caller. This is useful when you want to handle different cases depending on whether the parameter has a value or not. However, this predicate condition has nothing to do with the CAST operator or the type of the operand12.
IS NOT INITIAL: The IS NOT INITIAL predicate condition checks whether the operand has a non-initial value. This is useful when you want to check whether the operand has been assigned a value or not. However, this predicate condition does not guarantee that the CAST will work, because the operand may have a value but not be an instance of the target type12.
IS BOUND: The IS BOUND predicate condition checks whether the operand is a bound reference variable. This is useful when you want to check whether the operand points to an existing object or not. However, this predicate condition does not guarantee that the CAST will work, because the operand may point to an object but not be an instance of the target type12.

When you join two database tables, which of the following rules applies to the database fields you use in the join?
- A. They must always have an alias name.
- B. They must be compared with an ON condition.
- C. They must have the same name, e.g. col1 = col1.
- D. They must be the same position in their table, for example left_table-col1 = rigght_table-col1.
Answer: B
NEW QUESTION # 32
In a class you use the statement DATA var TYPE ...
What may stand in place of the type?
(Select 2 correct answers)
- A. The name of a type defined privately in class ZCL_CLASS_A
- B. The name of a data element from the ABAP Dictionary
- C. The name of a type defined privately in another class
- D. The name of a domain from the ABAP Dictionary
Answer: A,B
Explanation:
Comprehensive and Detailed Explanation from Exact Extract:
The ABAP DATA statement declares a variable with an assigned type.
* A. Private type in the same class (ZCL_CLASS_A) # # Allowed. A class can use its own local type definitions, declared using TYPES.
* B. Domain from ABAP Dictionary # # Not allowed directly. Domains define technical attributes but cannot be referenced directly in DATA; they must be wrapped in a data element.
* C. Type defined privately in another class # # Not accessible, since private definitions are encapsulated.
* D. Data element from ABAP Dictionary # # Allowed, because data elements are global dictionary objects.
This follows ABAP Cloud extensibility rules, ensuring encapsulation and strict typing.

NEW QUESTION # 33
How do you make class sub1 a subclass of class super1?
- A. In super1 use clause "sub1 REDEFINITION" in the IMPLEMENTATION part.
- B. In sub1 use clause "INHERITING FROM super1" in the DEFINITION part.
- C. In sub1 use clause "INHERITING FROM super1" in the IMPLEMENTATION part.
- D. In super1 use clause "sub1 REDEFINITION" in the DEFINITION part.
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
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 <superclass>.(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.)
NEW QUESTION # 34
Which of the following results in faster access to internal tables? Note: There are 3 correct answers to this question.
- A. In a sorted internal table, specifying the primary key partially from the left without gaps.
- B. In a hashed internal table, specifying the primary key completely.
- C. In a hashed internal table, specifying the primary key partially from the left without gaps.
- D. In a standard internal table, specifying the primary key partially from the left without gaps.
- E. In a sorted internal table, specifying the primary key completely.
Answer: B,C,E
Explanation:
The access to internal tables can be optimized by using the appropriate table type and specifying the table key. The table key is a set of fields that uniquely identifies a row in the table and determines the sorting order of the table. The table key can be either the primary key or a secondary key. The primary key is defined by the table type and the table definition, while the secondary key is defined by the user using the KEY statement1.
The following results in faster access to internal tables:
B . In a sorted internal table, specifying the primary key completely. A sorted internal table is a table type that maintains a predefined sorting order, which is defined by the primary key in the table definition. The primary key can be either unique or non-unique. A sorted internal table can be accessed using the primary key or the table index. The access using the primary key is faster than the access using the table index, because the system can use a binary search algorithm to find the row. However, the primary key must be specified completely, meaning that all the fields of the primary key must be given in the correct order and without gaps2.
D . In a hashed internal table, specifying the primary key partially from the left without gaps. A hashed internal table is a table type that does not have a predefined sorting order, but uses a hash algorithm to store and access the rows. The primary key of a hashed internal table must be unique and cannot be changed. A hashed internal table can only be accessed using the primary key, not the table index. The access using the primary key is very fast, because the system can directly calculate the position of the row using the hash algorithm. The primary key can be specified partially from the left without gaps, meaning that some of the fields of the primary key can be omitted, as long as they are the rightmost fields and there are no gaps between the specified fields.
E . In a hashed internal table, specifying the primary key completely. A hashed internal table is a table type that does not have a predefined sorting order, but uses a hash algorithm to store and access the rows. The primary key of a hashed internal table must be unique and cannot be changed. A hashed internal table can only be accessed using the primary key, not the table index. The access using the primary key is very fast, because the system can directly calculate the position of the row using the hash algorithm. The primary key can be specified completely, meaning that all the fields of the primary key must be given in the correct order.
The following do not result in faster access to internal tables, because:
A . In a sorted internal table, specifying the primary key partially from the left without gaps. A sorted internal table is a table type that maintains a predefined sorting order, which is defined by the primary key in the table definition. The primary key can be either unique or non-unique. A sorted internal table can be accessed using the primary key or the table index. The access using the primary key is faster than the access using the table index, because the system can use a binary search algorithm to find the row. However, the primary key must be specified completely, meaning that all the fields of the primary key must be given in the correct order and without gaps. If the primary key is specified partially from the left without gaps, the system cannot use the binary search algorithm and has to perform a linear search, which is slower2.
C . In a standard internal table, specifying the primary key partially from the left without gaps. A standard internal table is a table type that does not have a predefined sorting order, but uses a sequential storage and access of the rows. The primary key of a standard internal table is the standard key, which consists of all the fields of the table row in the order in which they are defined. A standard internal table can be accessed using the primary key or the table index. The access using the primary key is slower than the access using the table index, because the system has to perform a linear search to find the row. The primary key can be specified partially from the left without gaps, but this does not improve the access speed, because the system still has to perform a linear search.
NEW QUESTION # 35
when you attempt to activate the definition, what will be the response?
- A. Activation error because the key fields of the union do not match
- B. Activation error because the field names of the union do not match
- C. Activation error because the field types of the union do not match
- D. Activation successful
Answer: B
Explanation:
The response will be an activation error because the field names of the union do not match. This is because the field names of the union must match in order for the definition to be activated. The union operator combines the result sets of two or more queries into a single result set. The queries that are joined by the union operator must have the same number and type of fields, and the fields must have the same names1. In the given code, the field names of the union do not match, because the first query has the fields carrname, connid, cityfrom, and cityto, while the second query has the fields carrname, carrier_id, cityfrom, and cityto. The field connid in the first query does not match the field carrier_id in the second query. Therefore, the definition cannot be activated.
