C_CPI_15 SAP Certified Development Associate - SAP Integration Suite Questions and Answers

The API Management capability of the SAP Integration Suite requires API providers to incorporate APIs from source systems. An API provider is a system or application that exposes the interface and functionality of an API. The API Management capability allows you to connect to different types of API providers, such as OData, SOAP, REST, or RFC, and manage their lifecycle, security, and consumption. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

Some advantages of the cloud integration capability within SAP Integration Suite are:

• A local installation is not required. The cloud integration capability is a cloud-based service that runs on SAP Business Technology Platform (BTP). It does not require any installation or maintenance on your local system. You can access it from any web browser and start developing and deploying integration flows using a graphical user interface or an Eclipse-based tooling.
• Predefined scenarios can be used out-of-the-box. The cloud integration capability provides a rich set of predefined integration scenarios that cover various use cases and domains, such as SAP-to-SAP integration, SAP-to-non-SAP integration, hybrid integration, process orchestration, and so on. You can browse and discover these scenarios from the Discover page of the cloud integration web UI or from the SAP API Business Hub. You can use these scenarios as they are or customize them according to your needs. References: Cloud Integration Capability Overview | SAP Help Portal, Discover Integration Content | SAP Help Portal

To find out which entity sets are available in the OData V2.0 interface, you must retrieve the metadata document from the interface. The metadata document is an XML document that describes the data model of the OData service, including the entity types, entity sets, associations, functions, and actions. The metadata document can be accessed by appending $metadata to the service root URL of the OData service. For example, if the service root URL is https://services.odata.org/OData/OData.svc/, then the metadata document URL is https://services.odata.org/OData/OData.svc/$metadata. The metadata document can be used to discover the structure and capabilities of the OData service and to generate client code or proxies. References: Overview (OData Version 2.0) | OData - The Best Way to REST, OData API v2 Reference | SAP Help Portal

You use exception-handling subprocesses in an integration flow to handle unexpected errors. Exception-handling subprocesses are special types of subprocesses that are triggered when an error occurs in the main process or another subprocess. You can define custom actions and logic to handle different types of errors using exception-handling subprocesses. References:  Modernize Integration with SAP Integration Suite | openSAP

To prevent overload in an OData request and reply call, you can use paging. Paging is a technique that allows you to retrieve a large number of data sets in smaller chunks or pages. You can use the OData query options $top and $skip to specify how many records you want to fetch and how many records you want to skip in each request. This reduces the network load and improves the performance of the OData service. References: OData API | SAP Help Portal, SAP Integration Suite: enrich a payload with OData Service | SAP Blogs

To connect an SAP backend system through the Cloud Connector with an API provider, you must use the on-premise connection type. The Cloud Connector acts as a link between SAP Integration Suite and on-premise systems, enabling secure and controlled access to the backend resources. The on-premise connection type allows you to specify the internal host and port of the backend system, as well as the virtual host and port that will be exposed to SAP Integration Suite. You can also define access control rules and protocols for the on-premise connection. References: Part 2: Connect to on-premise APIs from SAP Cloud Platform API Management Cloud Foundry Environment | SAP Blogs, How to configure SAP Cloud Connector & Create API using SCP API Management | SAP Blogs

 In the Cloud Integration capability within SAP Integration Suite, XML is the internal message format that is used. XML stands for Extensible Markup Language and is a standard format for representing structured data. All messages that are processed by the Cloud Integration capability are converted to XML internally and then transformed to the desired format at the outbound channel. References:   Modernize Integration with SAP Integration Suite | openSAP

You can configure a static payload in a Data Store Operation component or in a Content Modifier component of the Message Body tab. A Data Store Operation component allows you to store or retrieve messages in a data store. You can use the Write operation to store a static payload in a data store entry with a specified key. A Content Modifier component allows you to modify the message content, headers, and properties. You can use the Message Body tab to define a static payload for the message. References:  Modernize Integration with SAP Integration Suite | openSAP

To access the message body of the previous Content Modifier step in an integration flow, you must use the notation S{in body) in the current Content Modifier step. This notation means that you want to read the value from the in-message body of the exchange container. The exchange container is used to store additional data besides the message that is being processed by SAP Integration Suite. It has two message containers: in-message and out-message. The in-message contains the original message that was received by the integration flow, while the out-message contains the modified message that will be sent by the integration flow. References: Content Modifier Basics | SAP Help Portal, Exchange Container | SAP Help Portal

After creating an API in the API management capability within SAP Integration Suite using Edit in API Designer, the next step to consolidate the resources is to generate the server stubs. Server stubs are code snippets that implement the API operations on a server-side application. They can be generated in different languages and frameworks, such as Java, Node.js, Python, or Spring Boot. Generating server stubs can help you to quickly prototype and test your API functionality without writing much code. References: Create an API Using the API Designer | SAP Help Portal, Generate Server Stubs | SAP Tutorials

To test a connection to a backend system that is provided by a Cloud Connector, you must specify the location ID as a parameter for the connection test. The location ID is a unique identifier that represents a Cloud Connector instance in a specific network location. It is used to route requests from SAP Integration Suite to the correct Cloud Connector instance and then to the backend system. You can find the location ID in the Cloud Connector administration UI under Configuration Location ID. References: Cloud Connector Connectivity Tests | SAP Help Portal, Cloud Connector Configuration | SAP Help Portal

The “Trace” log level expires after 10 minutes and the log files are removed after 1 hour. The “Trace” log level is the most detailed log level that can be set for an integration flow. It records all the information about the message processing, such as headers, properties, payloads, attachments, and exceptions. However, it also consumes more resources and storage space than other log levels. Therefore, it is recommended to use it only for troubleshooting purposes and for a short duration. The “Trace” log level can be activated from the Monitor Message Processing view or from the integration flow editor. References: Log Levels | SAP Help Portal, Activating Trace Log Level | SAP Help Portal

You can use an HTTPS adapter to call an OData v4.0 interface in the Cloud Integration capability within SAP Integration Suite. An HTTPS adapter allows you to send and receive messages over HTTP or HTTPS protocols. You can use an HTTPS adapter to communicate with RESTful services, such as OData v4.0, that support HTTP methods and formats. References: Integration Software | SAP Integration Suite, Modernize Integration with SAP Integration Suite | openSAP

The messaging model of the Apache Camel Data Model consists of three parts: header, body, and attachment. The header contains information related to the message, such as addressing, routing, or metadata. The body contains the payload or the content of the message. The attachment contains optional data that can be attached to the message, such as files or images. The Apache Camel Data Model is used by SAP Integration Suite to process messages of any format using various components and data formats. References: The Camel Data Model in a Nutshell | SAP Help Portal, Data Formats :: Apache Camel

An API proxy is an API that acts as a proxy for another API, which is usually the backend service that provides the actual functionality. An API proxy can be used to add security, monitoring, caching, transformation, and other features to the backend API. An API provider is a logical grouping of APIs that share a common connection to the backend service. An API provider can be used to discover and import APIs from the backend service into the API Management capability within SAP Integration Suite. The relationship between an API provider and an API proxy is that the API proxy uses the API provider as a source of information and configuration for accessing the backend service. The API proxy also provides a unique URL that can be used by clients to invoke the API without exposing the details of the backend service. References: SAP Integration Suite | SAP Community, Create an API Proxy | SAP Tutorials
