The object that can be used to set a field to read-only in all applications of the RESTful Application Programming model (RAP) is the behaviour definition. The behaviour definition is a CDS artefact that defines the business logic and the UI behaviour of a business object. A business object is a CDS entity that represents a business entity or concept, such as a customer, an order, or a product. The behaviour definition can specify the properties of the fields of a business object, such as whether they are mandatory, read-only, or transient.These properties are valid for all applications that use the business object, such as transactional, analytical, or draft-enabled apps12. For example:

The following code snippet defines a behaviour definition for a business object ZI_PB_APPLICATION. It sets the field APPLICATION to read-only for all applications that use this business object:

define behavior for ZI_PB_APPLICATION { field ( read only ) APPLICATION; ... }

You cannot do any of the following:

A . Service definition: A service definition is a CDS artefact that defines the interface and the binding of a service. A service is a CDS entity that exposes the data and the functionality of one or more business objects as OData, InA, or SQL services. A service definition can specify the properties of the fields of a service, such as whether they are filterable, sortable, or aggregatable.However, these properties are only valid for the specific service that uses the business object, not for all applications that use the business object12.

C . Projection view: A projection view is a CDS artefact that defines a view on one or more data sources, such as tables, views, or associations. A projection view can select, rename, or aggregate the fields of the data sources, but it cannot change the properties of the fields, such as whether they are read-only or not.The properties of the fields are inherited from the data sources or the behaviour definitions of the business objects12.

D . Metadata extension: A metadata extension is a CDS artefact that defines additional annotations for a CDS entity, such as a business object, a service, or a projection view. A metadata extension can specify the properties of the fields of a CDS entity for UI or analytical purposes, such as whether they are visible, editable, or hidden.However, these properties are only valid for the specific UI or analytical application that uses the metadata extension, not for all applications that use the CDS entity12.

ABAP SQL arithmetic expressions have different restrictions depending on the data type of the operands. The following are some of the restrictions:

Floating point types and integer types can be used in the same expression, as long as the integer types are cast to floating point types using the cast function. For example,CAST ( num1 AS FLTP ) / CAST ( num2 AS FLTP )is a valid expression, where num1 and num2 are integer types.

The operator / is allowed only in floating point expressions, where both operands have the type FLTP or f. For example,num1 / num2is a valid expression, where num1 and num2 are floating point types. If the operator / is used in an integer expression or a decimal expression, a syntax error occurs.

Decimal types and integer types can be used in the same expression, as long as the expression is a decimal expression. A decimal expression has at least one operand with the type DEC, CURR, or QUAN or p with decimal places. For example,num1 + num2is a valid expression, where num1 is a decimal type and num2 is an integer type.

The operator ** is allowed only in floating point expressions, where both operands have the type FLTP or f. For example,num1 ** num2is a valid expression, where num1 and num2 are floating point types. If the operator ** is used in an integer expression or a decimal expression, a syntax error occurs.

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.

The annotation that can be used to provide a short description of the data definition for developers that will be attached to the database view is the @EndUserText.label annotation. This annotation is used to specify a text label for the data definition that can be displayed in the development tools or in the documentation.The annotation can be inserted on line #27 in the code snippet provided in the question12. For example:

The following code snippet uses the @EndUserText.label annotation to provide a short description of the data definition for the CDS view ZCDS_VIEW:

@AbapCatalog.sqlViewName: 'ZCDS_VIEW' @AbapCatalog.compiler.compareFilter: true @AbapCatalog.preserveKey: true @AccessControl.authorizationCheck: #CHECK @EndUserText.label: 'CDS view for flight data' 'short description for developers define view ZCDS_VIEW as select from sflight { key carrid, key connid, key fldate, seatsmax, seatsocc }

You cannot do any of the following:

@UI.headerInfo.description.label: This annotation is used to specify a text label for the description field of the header information of a UI element.This annotation is not relevant for the data definition of a database view12.

@UI.badge.title.label: This annotation is used to specify a text label for the title field of a badge UI element.This annotation is not relevant for the data definition of a database view12.

@EndUserText.quickInfo: This annotation is used to specify a quick information text for the data definition that can be displayed as a tooltip in the development tools or in the documentation.This annotation is not the same as a short description or a label for the data definition12.

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.
