Using ABAP SQL, the select statement that selects the mat field on line #17 is:

SELECT mat FROM demo_sales_cds_so_i_ve...

This statement selects the mat field from the CDS view demo_sales_cds_so_i_ve, which is defined on line #1. The CDS view demo_sales_cds_so_i_ve is a projection view that projects the fields of the CDS view demo_sales_cds_so_i, which is defined on line #2. The CDS view demo_sales_cds_so_i is a join view that joins the fields of the database table demo_sales_so_i, which is defined on line #3, and the CDS view demo_sales_cds_material_ve, which is defined on line #4. The CDS view demo_sales_cds_material_ve is a value help view that provides value help for the material field of the database table demo_sales_so_i.The mat field is an alias for the material field of the database table demo_sales_so_i, which is defined on line #91.

The other options are not valid because:

A) SELECT mat FROM Material... is not valid because Material is not a valid data source in the given code. There is no CDS view or database table named Material.

C) SELECT mat FROM demo_sales_so_i... is not valid because demo_sales_so_i is not a valid data source in the given code. There is no CDS view named demo_sales_so_i, only a database table. To access a database table, the keyword TABLE must be used, such as SELECT mat FROM TABLE demo_sales_so_i...

D) SELECT mat FROM demo sales cds material ve... is not valid because demo sales cds material ve is not a valid data source in the given code. There is no CDS view or database table named demo sales cds material ve. The correct name of the CDS view is demo_sales_cds_material_ve, with underscores instead of spaces.

The code snippet in the image is an example of using the RAISE EXCEPTION statement to raise a class-based exception and create a corresponding exception object.The code snippet also uses the EXPORTING addition to pass parameters to the instance constructor of the exception class12. Some of the valid statements about the code snippet are:

The code creates an exception object and raises an exception: This is true. The RAISE EXCEPTION statement raises the exception linked to the exception class zcxl and generates a corresponding exception object.The exception object contains the information about the exception, such as the message, the source position, and the previous exception12.

''previous'' expects the reference to a previous exception: This is true. The previous parameter is a predefined parameter of the instance constructor of the exception class cx_root, which is the root class of all class-based exceptions. The previous parameter expects the reference to a previous exception object that was caught during exception handling.The previous parameter can be used to chain multiple exceptions and preserve the original cause of the exception12.

You cannot do any of the following:

''zcxl'' is a dictionary structure, and ''paraml'' and ''param2'' are this structure: This is false. zcxl is not a dictionary structure, but a user-defined exception class that inherits from the predefined exception class cx_static_check. param1 and param2 are not components of this structure, but input parameters of the instance constructor of the exception class zcxl.The input parameters can be used to pass additional information to the exception object, such as the values that caused the exception12.

''paraml'' and ''param2'' are predefined names: This is false. param1 and param2 are not predefined names, but user-defined names that can be chosen arbitrarily. However, they must match the names of the input parameters of the instance constructor of the exception class zcxl.The names of the input parameters can be declared in the interface of the exception class using the RAISING addition12.

The function module ZF1 is in a software component with the language version set to ''ABAP Cloud''. This means that it follows the ABAP Cloud Development Model, which requires the usage of public SAP APIs and extension points to access SAP functionality and data.These APIs and extension points are released by SAP and documented in the SAP API Business Hub1. Customer-created function modules are not part of the public SAP APIs and are not released for cloud development. Therefore, calling a function module directly from a class with the language version set to ''Standard ABAP'' is not allowed and will result in a syntax error. However, there is a possible way to call a function module indirectly from a class with the language version set to ''Standard ABAP'':

Create a wrapper class or interface for the function module and release it for cloud development. A wrapper is a class or interface that encapsulates the function module and exposes its functionality through public methods or attributes. The wrapper must be created in a software component with the language version set to ''ABAP Cloud'' and must be marked as released for cloud development using the annotation @EndUserText.label.The wrapper can then be called from a class with the language version set to ''Standard ABAP'' using the public methods or attributes2.

For example, the following code snippet shows how to create a wrapper class for the function module ZF1 and call it from the class zcl_demo_class:

@EndUserText.label: 'Wrapper for ZF1' CLASS zcl_wrapper_zf1 DEFINITION PUBLIC FINAL CREATE PUBLIC. PUBLIC SECTION. CLASS-METHODS: call_zf1 IMPORTING iv_a TYPE i iv_b TYPE i EXPORTING ev_result TYPE i. ENDCLASS.

CLASS zcl_wrapper_zf1 IMPLEMENTATION. METHOD call_zf1. CALL FUNCTION 'ZF1' EXPORTING a = iv_a b = iv_b IMPORTING result = ev_result. ENDMETHOD. ENDCLASS.

CLASS zcl_demo_class DEFINITION. METHODS: m1. ENDCLASS.

CLASS zcl_demo_class IMPLEMENTATION. METHOD m1. DATA(lv_result) = zcl_wrapper_zf1=>call_zf1( iv_a = 2 iv_b = 3 ). WRITE: / lv_result. ENDMETHOD. ENDCLASS.

The output of this code is:

When accessing the subclass instance through go_super, you can do both of the following:

Access the inherited private components: A subclass inherits all the private attributes and methods of its superclass, unless they are explicitly overridden by the subclass.Therefore, you can access the inherited private components of the superclass through go_super, as long as they are not hidden by other attributes or methods in the subclass12.

Access the inherited public components: A subclass inherits all the public attributes and methods of its superclass, unless they are explicitly overridden by the subclass.Therefore, you can access the inherited public components of the superclass through go_super, as long as they are not hidden by other attributes or methods in the subclass12.

You cannot do any of the following:

Call a subclass specific public method: A subclass does not have any public methods that are not inherited from its superclass.Therefore, you cannot call a subclass specific public method through go_super12.

Call inherited public redefined methods: A subclass does not have any public methods that are redefined from its superclass.Therefore, you cannot call inherited public redefined methods through go_super12.

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.

The statement that can be used to expose the field ''connid'' of the data source ''demo_ods_assoc_spfli'' in the element list is A. demo_ods_assoc_spfli.connid,. This statement uses the dot notation to access the field ''connid'' of the data source ''demo_ods_assoc_spfli'', which is an association defined on line #4. The association ''demo_ods_assoc_spfli'' links the data source ''demo_ods'' with the table ''spfli'' using the field ''carrid''.The statement also ends with a comma to separate it from the next element in the list12.

You cannot do any of the following:

B) demo_ods_assoc_spfli-connid/: This statement uses the wrong syntax to access the field ''connid'' of the data source ''demo_ods_assoc_spfli''. The dash notation is used to access the components of a structure or a table, not the fields of a data source.The statement also ends with a slash, which is not a valid separator for the element list12.

C) spfli-connid,: This statement uses the wrong data source name to access the field ''connid''. The data source name should be ''demo_ods_assoc_spfli'', not ''spfli''.The statement also uses the wrong syntax to access the field ''connid'', as explained above12.

D) _spfli.connid/: This statement uses the wrong data source name and the wrong separator to access the field ''connid''. The data source name should be ''demo_ods_assoc_spfli'', not ''_spfli''.The statement also ends with a slash, which is not a valid separator for the element list12.

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.

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:

A) ON Z_Sourcel.camer_id = 7_Source2 carrier_id is not valid because Z_Sourcel and 7_Source2 are not valid data sources in the given code. There is no CDS view or database table named Z_Sourcel or 7_Source2. The correct names are Z_Source1 and Z_Source2. Moreover, the field camer_id is not a valid field in the given code. There is no field named camer_id in any of the data sources. The correct name is carrier_id.

B) ON Sprojection Camer=Source2 carrier_id is not valid because Sprojection and Source2 are not valid data sources in the given code. There is no CDS view or database table named Sprojection or Source2. The correct names are Sprojection and Z_Source2. Moreover, the field Camer is not a valid field in the given code. There is no field named Camer in any of the data sources. The correct name is carrier_id.Furthermore, the ON condition is missing the dot (.) operator between the data source name and the field name, which is required to access the fields of the data source1.

C) ON Sprojection. Carrier Source2.carrier is not valid because Carrier and carrier are not valid fields in the given code. There is no field named Carrier or carrier in any of the data sources. The correct name is carrier_id.Moreover, the ON condition is missing the dot (.) operator between the data source name and the field name, which is required to access the fields of the data source1.

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
