NEW QUESTION # 18
In class ZCL_CLASS_A, you use the statement DATA var TYPE ***
What may stand in place of ***? Note: There are 2 correct answers to this question.
- A. The name of a domain from the ABAP Dictionary
- B. The name of a type defined privately in another class
- C. The name of a type defined privately in class ZCL_CLASS_A
- D. The name of a data element from the ABAP Dictionary
Answer: A,D
Explanation:
In class ZCL_CLASS_A, you use the statement DATA var TYPE *** to declare a data object named var with a data type specified by ***. The data type can be any of the following1:
* A predefined ABAP type, such as i, f, c, string, xstring, and so on.
* A data element from the ABAP Dictionary, such as matnr, carrid, bukrs, and so on. A data element defines the semantic and technical attributes of a data field, such as the domain, the length, the data type, the description, and the value range2.
* A domain from the ABAP Dictionary, such as matnr_d, carrid_d, bukrs_d, and so on. A domain defines the technical attributes of a data field, such as the data type, the length, the output length, the number of decimal places, and the value range3.
* A type defined globally in a class, an interface, or a type pool, such as zcl_class_b=>type_a, zif_interface_c=>type_b, ztype_pool_d=>type_c, and so on. A global type is a type that is defined in a global repository object and can be used in any program or class4.
* A type defined locally in the current class, such as type_a, type_b, type_c, and so on. A local type is a type that is defined in the declaration part of a class and can only be used within the class5.
Therefore, the possible values for *** are B. the name of a data element from the ABAP Dictionary and D. the name of a domain from the ABAP Dictionary. The other options are not valid because:
* A. The name of a type defined privately in class ZCL_CLASS_A is a local type and cannot be used with the DATA statement. A local type can only be used with the TYPES statement5.
* C. The name of a type defined privately in another class is a private type and cannot be accessed from outside the class. A private type can only be used within the class that defines it.

NEW QUESTION # 19
What are the effects of this annotation? Note: There are 2 correct answers to this question.
- A. The value of sy-langu will be passed to the CDS view automatically both when you use the -1 CDS view in ABAP and in another CDS view entity (view on view).
- B. You can still override the default value with a value of your own.
- C. It is no longer possible to pass your own value to the parameter.
- D. The value of sy-langu will be passed to the CDS view automatically when you use the CDS view in ABAP but not when you use it in another view entity
Answer: A,B
Explanation:
The annotation @Environment.systemField: #LANGUAGE is used to assign the ABAP system field sy-langu to an input parameter of a CDS view or a CDS table function. This enables the implicit parameter passing in Open SQL, which means that the value of sy-langu will be automatically passed to the CDS view without explicitly specifying it in the WHERE clause. This also applies to the CDS views that use the annotated CDS view as a data source, which means that the value of sy-langu will be propagated to the nested CDS views (view on view)12. For example:
* The following code snippet defines a CDS view ZI_FLIGHT_TEXTS with an input parameter p_langu that is annotated with @Environment.systemField: #LANGUAGE:
define view ZI_FLIGHT_TEXTS with parameters p_langu : syst_langu @<Environment.systemField:
#LANGUAGE as select from sflight left outer join scarr on sflight.carrid = scarr.carrid left outer join stext on scarr.carrid = stext.carrid { sflight.carrid, sflight.connid, sflight.fldate, scarr.carrname, stext.text as carrtext } where stext.langu = :p_langu
* The following code snippet shows how to use the CDS view ZI_FLIGHT_TEXTS in ABAP without specifying the value of p_langu in the WHERE clause. The value of sy-langu will be automatically passed to the CDS view:
SELECT carrid, connid, fldate, carrname, carrtext FROM zi_flight_texts INTO TABLE @DATA(lt_flights).
* The following code snippet shows how to use the CDS view ZI_FLIGHT_TEXTS in another CDS view ZI_FLIGHT_REPORT. The value of sy-langu will be automatically passed to the nested CDS view ZI_FLIGHT_TEXTS:
define view ZI_FLIGHT_REPORT with parameters p_langu : syst_langu @<Environment.systemField:
#LANGUAGE as select from zi_flight_texts(p_langu) { carrid, connid, fldate, carrname, carrtext, count(*) as flight_count } group by carrid, connid, fldate, carrname, carrtext The annotation @Environment.systemField: #LANGUAGE does not prevent the possibility of overriding the default value with a value of your own. You can still specify a different value for the input parameter p_langu in the WHERE clause, either in ABAP or in another CDS view. This will override the value of sy-langu and pass the specified value to the CDS view12. For example:
* The following code snippet shows how to use the CDS view ZI_FLIGHT_TEXTS in ABAP with a specified value of p_langu in the WHERE clause. The value 'E' will be passed to the CDS view instead of the value of sy-langu:
SELECT carrid, connid, fldate, carrname, carrtext FROM zi_flight_texts WHERE p_langu = 'E' INTO TABLE @DATA(lt_flights).
* The following code snippet shows how to use the CDS view ZI_FLIGHT_TEXTS in another CDS view ZI_FLIGHT_REPORT with a specified value of p_langu in the WHERE clause. The value 'E' will be passed to the nested CDS view ZI_FLIGHT_TEXTS instead of the value of sy-langu:
define view ZI_FLIGHT_REPORT with parameters p_langu : syst_langu @<Environment.systemField:
#LANGUAGE as select from zi_flight_texts(p_langu) { carrid, connid, fldate, carrname, carrtext, count(*) as flight_count } where p_langu = 'E' group by carrid, connid, fldate, carrname, carrtext References: 1: ABAP CDS - parameter_annot - ABAP Keyword Documentation - SAP Online Help 2: ABAP CDS - session_variable - ABAP Keyword Documentation - SAP Online Help
NEW QUESTION # 20
Exhibit:
Which of the following statements are correct? Note: There are 2 correct answers to this question.
- A. row is a predefined name and cannot be chosen arbitrarily.
- B. source_itab is only visible within the loop.
- C. row is only visible within the loop.
- D. FOR defines a loop that runs over the content of source_itab
Answer: C,D
Explanation:
The code snippet in the image is an example of using the FOR statement to create an internal table with a constructor expression. The FOR statement introduces an iteration expression that runs over the content of source_itab and assigns each row to the variable row. The variable row is then used to populate the fields of target_itab12. Some of the correct statements about the code snippet are:
* FOR defines a loop that runs over the content of source_itab: This is true. The FOR statement iterates over the rows of source_itab and assigns each row to the variable row. The iteration expression can also specify a range or a condition for the loop12.
* row is only visible within the loop: This is true. The variable row is a local variable that is only visible within the scope of the iteration expression. It cannot be accessed outside the loop12.
You cannot do any of the following:
* source_itab is only visible within the loop: This is false. The variable source_itab is not a local variable that is defined by the FOR statement. It is an existing internal table that is used as the data source for the iteration expression. It can be accessed outside the loop12.
* row is a predefined name and cannot be chosen arbitrarily: This is false. The variable row is not a predefined name that is reserved by the FOR statement. It is a user-defined name that can be chosen arbitrarily. However, it must not conflict with any existing names in the program12.

NEW QUESTION # 21
What are some properties of database tables? Note: There are 2 correct answers to this question.
- A. They can have relationships to other tables.
- B. They can have any number of key fields.
- C. They may have key fields.
- D. They store information in two dimensions.
Answer: A,D
Explanation:
Explanation
Database tables are data structures that store information in two dimensions, using rows and columns. Each row represents a record or an entity, and each column represents an attribute or a field. Database tables may have key fields, which are columns that uniquely identify each row or a subset of rows. Key fields can be used to enforce data integrity, perform efficient searches, and establish relationships to other tables. Database tables can have relationships to other tables, which are associations or links between the key fields of two or more tables. Relationships can be used to model the logical connections between different entities, join data from multiple tables, and enforce referential integrity12.

NEW QUESTION # 23
In this nested join below in which way is the join evaluated?
- A. From the bottom to the top in the order of the on conditions:
1.
a is joined with b
2.
b is joined with c - B. From the left to the right in the order of the tables:
1.
a is joined with b
2.
b is joined with c - C. From the right to the left in the order of the tables:
1.
b is joined with c.
2.
b is joined with a. - D. From the top to the bottom in the order of the on conditions
1.
b is joined with c
2.
a is joined with b
Answer: D
Explanation:
The nested join is evaluated from the top to the bottom in the order of the ON conditions. This means that the join expression is formed by assigning each ON condition to the directly preceding JOIN from left to right.
The join expression can be parenthesized implicitly or explicitly to show the order of evaluation. In this case, the implicit parentheses are as follows:
SELECT * FROM (a INNER JOIN (b INNER JOIN c ON b~c = c~c) ON a~b = b~b) This means that the first join expression is b INNER JOIN c ON b~c = c~c, which joins the columns of tables b and c based on the condition that b~c equals c~c. The second join expression is a INNER JOIN (b INNER JOIN c ON b~c = c~c) ON a~b = b~b, which joins the columns of table a and the result of the first join expression based on the condition that a~b equals b~b. The final result set contains all combinations of rows from tables a, b, and c that satisfy both join conditions.

NEW QUESTION # 24
What is the sequence priority when evaluating a logical expression?
A) NOT 1
B) OR 3
C) AND 2
- A. A B C
- B. A C B
- C. CAB
- D. B A C
Answer: B
Explanation:
The sequence priority when evaluating a logical expression is C. A C B, which means NOT, AND, OR. This is the order of precedence of the Boolean operators in ABAP, which determines how the system implicitly parenthesizes all logical expressions that are not closed by explicit parentheses. The operator with the highest priority is evaluated first, and the operator with the lowest priority is evaluated last. The order of precedence of the Boolean operators in ABAP is as follows12:
NOT: The NOT operator is a unary operator that negates the logical expression that follows it. It has the highest priority and is evaluated before any other operator. For example, in the expression NOT a AND b, the NOT operator is applied to a first, and then the AND operator is applied to the result and b.
AND: The AND operator is a binary operator that returns true if both logical expressions on its left and right are true, and false otherwise. It has the second highest priority and is evaluated before the OR and EQUIV operators. For example, in the expression a AND b OR c, the AND operator is applied to a and b first, and then the OR operator is applied to the result and c.
OR: The OR operator is a binary operator that returns true if either or both logical expressions on its left and right are true, and false otherwise. It has the third highest priority and is evaluated after the NOT and AND operators, but before the EQUIV operator. For example, in the expression a OR b EQUIV c, the OR operator is applied to a and b first, and then the EQUIV operator is applied to the result and c.
EQUIV: The EQUIV operator is a binary operator that returns true if both logical expressions on its left and right have the same truth value, and false otherwise. It has the lowest priority and is evaluated after all other operators. For example, in the expression a AND b EQUIV c OR d, the EQUIV operator is applied to a AND b and c last, after the AND and OR operators are applied.
NEW QUESTION # 25
For the assignment, gv_target = gv_source.
which of the following data declarations will always work without truncation or rounding? Note: There are 2 correct answers to this question.
- A. DATA gv_source TYPE c. to DATA gv_target TYPE string.
- B. DATA gv_source TYPE string, to DATA gv_target TYPE c.
- C. DATA gv_source TYPE p LENGTH 8 DECIMALS 3. to DATA gv_target TYPE p LENGTH 16 DECIMALS 2.
- D. DATA gv_source TYPE d. to DATA gv_target TYPE string.
Answer: A,D
Explanation:
Explanation
The data declarations that will always work without truncation or rounding for the assignment gv_target = gv_source are B and C. This is because the target data type string is a variable-length character type that can hold any character string, including those of data types c (fixed-length character) and d (date). The assignment of a character or date value to a string variable will not cause any loss of information or precision, as the string variable will adjust its length to match the source value12.
You cannot do any of the following:
A: DATA gv_source TYPE string, to DATA gv_target TYPE c.: This data declaration may cause truncation for the assignment gv_target = gv_source. This is because the target data type c is a fixed-length character type that has a predefined length. If the source value of type string is longer than the target length of type c, the source value will be truncated on the right to fit the target length12.
D: DATA gv_source TYPE p LENGTH 8 DECIMALS 3. to DATA gv_target TYPE p LENGTH 16 DECIMALS 2.: This data declaration may cause rounding for the assignment gv_target = gv_source.
This is because the target data type p is a packed decimal type that has a predefined length and number of decimal places. If the source value of type p has more decimal places than the target type p, the source value will be rounded to the target number of decimal places12.

NEW QUESTION # 26
In an Access Control Object, which clauses are used? Note: There are 3 correct answers to this question.
- A. Revoke (to remove access to the data source)
- B. Define role (to specify the role name)
- C. Return code (to assign the return code of the authority check)
- D. Where (to specify the access conditions)
- E. Crant (to identify the data source)
Answer: A,B,D
Explanation:
An Access Control Object (ACO) is a CDS annotation that defines the access control rules for a CDS view entity. An ACO consists of one or more clauses that specify the role name, the data source, the access conditions, and the return code of the authority check12. Some of the clauses that are used in an ACO are:
* Where (to specify the access conditions): This clause is used to define the logical expression that determines whether a user has access to the data source or not. The expression can use the fields of the data source, the parameters of the CDS view entity, or the predefined variables $user and $session. The expression can also use the functions check_authorization and check_role to perform additional authority checks12.
* Define role (to specify the role name): This clause is used to assign a name to the role that is defined by the ACO. The role name must be unique within the namespace of the CDS view entity and must not contain any special characters. The role name can be used to reference the ACO in other annotations, such as @AccessControl.authorizationCheck or @AccessControl.grant12.
* Revoke (to remove access to the data source): This clause is used to explicitly deny access to the data source for a user who meets the conditions of the where clause. The revoke clause overrides any grant clause that might grant access to the same user. The revoke clause can be used to implement the principle of least privilege or to enforce data segregation12.
You cannot do any of the following:
* Grant (to identify the data source): This is not a valid clause in an ACO. The grant clause is a separate annotation that is used to grant access to a CDS view entity or a data source for a user who has a specific role. The grant clause can reference an ACO by its role name to apply the access conditions defined by the ACO12.
* Return code (to assign the return code of the authority check): This is not a valid clause in an ACO. The return code of the authority check is a predefined variable that is set by the system after performing the access control check. The return code can be used in the where clause of the ACO to specify different access conditions based on the outcome of the check12.

NEW QUESTION # 30
Which internal table type allows unique and non-unique keys?
- A. Sorted
- B. Hashed
- C. Standard
Answer: 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.
NEW QUESTION # 31 
To adhere to the most recent ABAP SQL syntax conventions from SAP, on which line must you insert the
"INTO TABLE @gt flights" clause to complete the SQL statement?
- A. #4
- B. #6
- C. #8
- D. #15
Answer: A
Explanation:
Explanation
To adhere to the most recent ABAP SQL syntax conventions from SAP, you must insert the "INTO TABLE
@gt flights" clause on line #4 to complete the SQL statement. This is because the INTO or APPENDING clause should be specified immediately after the SELECT clause, according to the ABAP SQL syntax conventions1. The INTO or APPENDING clause defines the data object to which the results set of the SELECT statement is assigned. The data object can be an internal table, a work area, or an inline declaration.
In this case, the data object is an internal table named gt_flights, which is created using the inline declaration operator @DATA. The inline declaration operator allows you to declare and create a data object in the same statement where it is used, without the need for a separate DATA statement2.
The other lines are not suitable for inserting the "INTO TABLE @gt flights" clause, as they would violate the ABAP SQL syntax conventions or cause syntax errors. These lines are:
#6: This line is not suitable for inserting the "INTO TABLE @gt flights" clause, as it would cause a syntax error. This is because the FROM clause must be specified before the INTO or APPENDING clause, according to the ABAP SQL syntax conventions1. The FROM clause defines the data sources from which the data is read, such as database tables, CDS view entities, or CDS DDIC-based views. In this case, the data source is the database table flights.
#8: This line is not suitable for inserting the "INTO TABLE @gt flights" clause, as it would cause a syntax error. This is because the ORDER BY clause must be specified after the INTO or APPENDING clause, according to the ABAP SQL syntax conventions1. The ORDER BY clause defines the sort order of the results set of the SELECT statement. In this case, the results set is sorted by the fields carrid, connid, and fltime.
#15: This line is not suitable for inserting the "INTO TABLE @gt flights" clause, as it would violate the ABAP SQL syntax conventions. This is because the INTO or APPENDING clause should be specified as close as possible to the SELECT clause, according to the ABAP SQL syntax conventions1. The INTO or APPENDING clause should not be separated from the SELECT clause by other clauses, such as the WHERE clause, the GROUP BY clause, the HAVING clause, the UNION clause, or the ORDER BY clause. This is to improve the readability and maintainability of the ABAP SQL statement.

What is the sequence priority when evaluating a logical expression?
- A. A B C
- B. AND 2
- C. A C B
- D. OR 3
- E. CAB
- F. B A C
- G. NOT 1

NEW QUESTION # 35
In ABAP SQL, which of the following retrieves the association field_Airline-Name of a CDS view?
- A. \_Airline-Name
- B. /_Airline Name
- C. "_Airline Name
- D. @_Airline-Name
Answer: D
Explanation:
In ABAP SQL, the syntax to retrieve the association field of a CDS view is to use the @ sign followed by the association name and the field name, separated by a period sign (.). For example, to retrieve the association field _Airline-Name of a CDS view, the syntax is @_Airline.Name. This syntax allows the access to the fields of the target data source of the association without explicitly joining the data sources1. The other options are incorrect because they use the wrong symbols or formats to access the association field.

Which of the following integration frameworks have been released for ABAP cloud development? Note:
There are 3 correct answers to this question.
- A. Business Events
- B. CDS Views
- C. OData services
- D. SOAP consumption
- E. Business Add-ins (BAdls)
Answer: A,C,D
Explanation:
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.

NEW QUESTION # 37
In this nested join below in which way is the join evaluated?
- A. From the bottom to the top in the order of the on conditions:
1.
a is joined with b
2.
b is joined with c - B. From the left to the right in the order of the tables:
1.
a is joined with b
2.
b is joined with c - C. From the right to the left in the order of the tables:
1.
b is joined with c.
2.
b is joined with a. - D. From the top to the bottom in the order of the on conditions
1.
b is joined with c
2.
a is joined with b
Answer: D
Explanation:
The nested join is evaluated from the top to the bottom in the order of the ON conditions. This means that the join expression is formed by assigning each ON condition to the directly preceding JOIN from left to right.
The join expression can be parenthesized implicitly or explicitly to show the order of evaluation. In this case, the implicit parentheses are as follows:
SELECT * FROM (a INNER JOIN (b INNER JOIN c ON b~c = c~c) ON a~b = b~b) This means that the first join expression is b INNER JOIN c ON b~c = c~c, which joins the columns of tables b and c based on the condition that b~c equals c~c. The second join expression is a INNER JOIN (b INNER JOIN c ON b~c = c~c) ON a~b = b~b, which joins the columns of table a and the result of the first join expression based on the condition that a~b equals b~b. The final result set contains all combinations of rows from tables a, b, and c that satisfy both join conditions.

NEW QUESTION # 38
In an Access Control Object, which clauses are used? Note: There are 3 correct answers to this question.
- A. Revoke (to remove access to the data source)
- B. Define role (to specify the role name)
- C. Return code (to assign the return code of the authority check)
- D. Where (to specify the access conditions)
- E. Crant (to identify the data source)
Answer: A,B,D
Explanation:
An Access Control Object (ACO) is a CDS annotation that defines the access control rules for a CDS view entity. An ACO consists of one or more clauses that specify the role name, the data source, the access conditions, and the return code of the authority check12. Some of the clauses that are used in an ACO are:
Where (to specify the access conditions): This clause is used to define the logical expression that determines whether a user has access to the data source or not. The expression can use the fields of the data source, the parameters of the CDS view entity, or the predefined variables $user and $session. The expression can also use the functions check_authorization and check_role to perform additional authority checks12.
Define role (to specify the role name): This clause is used to assign a name to the role that is defined by the ACO. The role name must be unique within the namespace of the CDS view entity and must not contain any special characters. The role name can be used to reference the ACO in other annotations, such as @AccessControl.authorizationCheck or @AccessControl.grant12.
Revoke (to remove access to the data source): This clause is used to explicitly deny access to the data source for a user who meets the conditions of the where clause. The revoke clause overrides any grant clause that might grant access to the same user. The revoke clause can be used to implement the principle of least privilege or to enforce data segregation12.
You cannot do any of the following:
Grant (to identify the data source): This is not a valid clause in an ACO. The grant clause is a separate annotation that is used to grant access to a CDS view entity or a data source for a user who has a specific role. The grant clause can reference an ACO by its role name to apply the access conditions defined by the ACO12.
Return code (to assign the return code of the authority check): This is not a valid clause in an ACO. The return code of the authority check is a predefined variable that is set by the system after performing the access control check. The return code can be used in the where clause of the ACO to specify different access conditions based on the outcome of the check12.

NEW QUESTION # 40
Which field is defined incorrectly?
- A. field1
- B. field4
- C. field2
- D. field3
Answer: B
Explanation:
The field4 is defined incorrectly in the ABAP code snippet. The reason is that the data type c (character) cannot have a decimal places specification. The decimal places specification is only valid for the data types p (packed number) and f (floating point number)1. Therefore, the field4 definition should either omit the decimal places specification or change the data type to p or f.
