ABAP Cloud Development Quiz

The 'Count' function counts the occurrences of a substring within a string. The 'sub' keyword specifies the substring to search for. In this case, 'AB' occurs three times in the string 'ABAP ABAP abap'.

The 'find_any_of' function finds the first occurrence of a substring within a string. The '=' operator indicates that the substring is specified directly.

The 'find_any_not_of' function finds the position of the first character that doesn't match the specified substring. In this case, the first character that's not 'AB' is the first 'A' in 'ABAP'

The ABAP Cloud Development Model is used for SAP BTP, ABAP environment and SAP S/4HANA Cloud, public edition.

A Metadata extension allows you to organize the display of fields in a RESTful Application Programming (RAP) application.

Through the go_super keyword, you can access inherited public components of the superclass, as well as call redefined methods.

In the SAP S/4HANA Cloud private edition, function modules from a 'Standard ABAP' software component can only be called if they are released for cloud development.

Attaching a system field as an input parameter lets you pass the value of that field when the CDS view is used. You can still override this default value with your own value and it works both in ABAP and other CDS view entities.

Dividing an integer by another integer results in an integer value.

A class uses an interface by implementing it. The interface method 'if-m1' is named with the interface name 'if' and the method name 'm1'.

Casting a subclass object to its superclass is always possible, but casting a superclass object to a subclass is only possible if the superclass object was originally a subclass object.

You set the field to read-only in the 'Behavior definition' of your RAP application. This will ensure that the field is read-only in all applications in the model.

A unique secondary key is created when a table is first read and updated whenever the table is modified. This is needed to speed up accessing information in huge tables.

Access to sorted internal tables is faster when you specify the complete key or a part of the key from the left without gaps. This is because a sorted table is organized like a dictionary.

Built-in ABAP Dictionary types and data elements are valid replacements for '?'. A built-in ABAP type is not a valid replacement.

Numeric functions have the highest priority, followed by multiplication and division, and then addition and subtraction.

A database table definition includes a field list, which defines the fields it contains, and semantic table attributes that give the table its properties.

In RAP applications, you use data model views, behavior definitions, and metadata extensions to bind a CDS view to create a value help.

The ABAP types 'P' and 'C' are incomplete, meaning they require additional information like 'Decimals' or 'Length' to be fully defined. 'String' is a complete type and 'T' is not an ABAP type.

The following integration frameworks have been released for ABAP cloud development: OData services, Business Events, and SOAP consumption.

Go_if1 can call methods m1 and m2, and go_cl1 can call method m1. You can use 'go_if1 = NEW cl1(...)' instead of 'go_cl1 = NEW #()'.

Both SELECT statements: SELECT FROM /dmo/connection FIELDS MAX(distance) AS dist_max MIN(distance) AS dist_min INTO TABLE @DATA(It_hits). and SELECT FROM /dmo/connection FIELDS carrid, airpfrom, MAX(distance) AS dist_max, MIN( distance) AS dist_min GROUP BY carrid, airpfrom INTO TABLE @DATA(It_hits) are valid.

In an SAP S/4HANA Cloud private edition tenant, a function module from a 'ABAP Cloud' software component must be released for cloud development to be called.

In ABAP SQL, the association field name '_Airline-Name' retrieves the association field, connecting to another entity in the CDS view.

Sorted internal table types allow unique and non-unique keys.

Both fields and database tables can be assigned aliases in ABAP SQL.

DATA: gv_target TYPE p DECIMALS 3. CONSTANTS: gco_int1 TYPE i VALUE 2. gv_target = EXACT #(2 / gco_int1). causes an exception because integer division results in an integer value which cannot be assigned to a type p DECIMALS 3. The other two statements also cause exceptions due to type mismatches

Core Data Services (CDS) features include associations for linking entities, annotations to add metadata, and a Structured Query Language (SQL) to access data.

Access controls with CDS views enforce authorization checks without requiring explicit AUTHORITY CHECK statements and ensure only authorized data reaches the application layer.

You use the 'INTO' clause in ABAP SQL to create inline declarations.

A projection view contains only those fields that are required for a specific RAP application.

After you create a database table in the RAP model, create a data model view to connect the table to your application.

In ABAP class ZCL_CLASS_A, the statement 'DATA var TYPE...' can take the name of a type defined privately within the class or the name of a data element from the ABAP Dictionary.

SAP recommends using 'Key user' extensions to enhance the existing UI for an SAP Fiori app. This is because key user extensions allow for customization without requiring extensive coding.

In RAP, the 'Read entity' statement is used to retrieve an object.

Using a field symbol for internal table row access eliminates the need for a MODIFY statement and is faster than using a work area.

A foreign key relationship ensures data integrity by enforcing referential constraints between tables. This means that data in one table must match related data in another table.

The system variable 'sy-tabix' contains the current row number when processing an internal table using a LOOP.

When generating a RAP application, you first create a database table, followed by a data model view, then a service binding projection view, and finally a service definition.

Core Data Services are advantageous because they transfer computational results to the application server and implement code pushdown, which optimizes performance.

In RAP, the 'Validation' feature ensures the uniqueness of a semantic key by validating data input and preventing duplicate entries.

In the code provided, it has been assumed that 'zcx1' is dictionary structure and 'param1' and 'param2' are fields of that structure. This code creates an exception object and raises an exception. The exception raised and its content may be caught and processed by an exception handler. The 'previous' reference will point to the exception currently being handled.

The 'FOR' statement defines the loop using the content of 'source_itab' and 'row' is just a variable and can be chosen arbitrarily. Both 'source_itab' and 'row' are only visible within the loop.

On-stack developer extensions are recommended when you need to access SAP S/4HANA data using complex SQL or integrate data from different systems.

The @EndUserText.label annotation provides a short description of the CDS data definition, which can be helpful for developers.

Pragma is a pseudo-comment that is not checked by the syntax checker, but can be used for documentation or to provide information that may be useful for other tools. ##NEEDED and #EC_NEEDED are pseudo-comments, also not checked by the syntax checker but are used for system-specific purposes.

In an SAP S/4HANA Cloud private edition tenant, a function module in the same software component as a class can be called directly. No release for cloud development is needed.

Both CDS DDIC-based view and a database table from the ABAP Dictionary are valid types that can be used for the 'source' on line #4

Arithmetic expressions in ABAP SQL have restrictions when using the '/' operator and when combining decimal types with integer types. You can't divide variables of type I or P by variables of type P and vice versa, and you cannot combine types I and P in the same expression.

You should use a hashed table when you read a single record and specify the complete key, and a sorted table when you read a subset in a loop and specify a part of the key from the left without gaps

SAP recommends eliminating legacy code which is identical to a standard SAP object and code that has low usage. This reduces complexity and maintenance effort.

The system variable 'sy-index' contains the implicit loop counter when processing a loop using the 'DO... ENDDO' statement.

Changing the length of a domain or deleting a field from a structure that is part of a table definition causes indirect changes and requires a table conversion.

The constructor of the superclass must be called before using components of your own instance, and you can change the method signature of the subclass constructor.

Both 'contains_any_of()' and 'matches()' are predicate functions. A predicate function is a function that returns a boolean value (TRUE or FALSE) depending on a condition.

A business object in RAP consists of a CDS view that defines the data and a behavior definition that defines the logic and interactions for the object.

In the given definition of an SAP HANA database table, the field 'field1' is defined incorrectly because it lacks a data type. A data type specification is required for every field in a database table.

When creating an instance of a subclass, the constructors are executed in the following sequence: class constructor of superclass, instance constructor of superclass, class constructor of subclass, and instance constructor of subclass.

Database tables can have relationships to other tables, and they store information in two dimensions, with rows representing records and columns representing fields.

In nested joins, the join evaluation starts from the top to the bottom in the order of the ON conditions. This means that the 'b' table is joined with the 'c' table first, followed by the join of the 'a' table with the 'b' table.

In the CDS view entity data definition, the expression '_spfli.connid' selects the 'connid' field from the 'spfli' data source. This is a valid way to access fields within a CDS view entity.

In the scenario described, the customer can use the 'RAP BO Node Extension' to add the new button. This extension type allows for UI modifications in SAP Fiori elements applications and can be used to add new elements, functions, and behavior without modifying standard SAP code.

In a scenario where the program accesses a large table rarely, setting the 'Load Unit' to 'Column Loadable' and the 'Storage Type

Multiple secondary keys are allowed for any kind of internal table. Secondary keys are chosen explicitly when reading data, and hashed secondary keys do not need to be unique. However, sorted secondary keys do not need to be unique.

Both '$session.system_date' and ' @(cl_abap_context_info->get_system_date ())' are valid ABAP SQL expressions that can provide a value for the 'p_date' parameter in the CDS view entity.

The correct ON condition to use for the join is '$projection.carrier_id = _source2.carrier_id'. This condition ensures that the 'carrier_id' field in the projection (called '$projection') is matched with the 'carrier_id' field in the 'Source2' data source.

Fields with the same name and type will be copied from itab2 to itab1, and itab1 and itab2 must have at least one field name in common. However, fields with different types can be copied, but there might be data loss or type conversion issues.

The correct ABAP SQL expression to change 'mr joe doe' into 'JOE' is 'substring(upper('mr joe doe'), 4, 3) AS f2_sub_up'. This expression converts the string to uppercase and extracts the substring starting at the 4th character and taking 3 characters.

The data declarations 'DATA gv_source TYPE d. to DATA gv_target TYPE string.' and 'DATA gv_source TYPE c. to DATA gv_target TYPE string.' will always work without truncation or rounding because the target types (string) are large enough to accommodate the source values. Types c and d are compatible with string.

The activation will result in an error because the key fields of the union do not match. This is because a union requires that the key fields of the participating entities have the same name and data type.

The SELECT statement 'SELECT mat FROM demo_sales_cds_so_i_ve...' selects the 'mat' field from the 'demo_sales_cds_so_i_ve' view entity. This is because the 'mat' field is defined in this entity.

An INDEX TABLE is a generic internal table type. It is not a specific type but rather a general term used for any internal table that is not specifically SORTED or HASHED. This is the base type upon which other table types are built.

The variable 'connection_full' is typed as a structure. This is because it is declared using the type name of a CDS view, which represents a structure.

Both SELECT statements are valid. In the first, the CASE statement uses ELSE to handle all other cases, while the second uses WHEN OTHERS. Both syntaxes provide valid ways to assign values based on conditions within an ABAP SQL SELECT statement.
