SAP API Management, a core capability of the SAP Integration Suite, is designed to manage, secure, and publish synchronous, web-based APIs. It provides direct, out-of-the-box support for creating API proxies from backend services that expose industry-standard protocols. These include REST (Representational State Transfer) APIs, often described using OpenAPI specifications; SOAP (Simple Object Access Protocol) web services, defined by WSDL files; and OData (Open Data Protocol), a REST-based protocol for which API Management can parse metadata (EDMX) to understand the service structure. These three protocols represent the primary types of endpoints that API Management is built to handle.

B. RFC: RFC (Remote Function Call) is a proprietary SAP protocol for synchronous communication between SAP systems and is not a web-based protocol directly managed by API Management.

E. IDoc: IDoc (Intermediate Document) is a standard SAP data container for asynchronous data exchange, not a synchronous request-response protocol that API Management proxies.

1. SAP Help Portal

SAP Integration Suite Documentation: In the section on API Management

the process for creating an API proxy explicitly lists the supported sources. It states

"You can create an API from: ... A service definition. Supported service definitions are: OpenAPI

WSDL

RAML

EDMX

and WADL."

OpenAPI corresponds to REST.

WSDL (Web Services Description Language) corresponds to SOAP.

EDMX (Entity Data Model for XML) corresponds to OData.

This documentation does not list RFC or IDoc as directly supported sources for API proxy creation.

SAP Cloud Integration is built upon the Apache Camel integration framework. It utilizes Apache Camel's Simple Expression Language as the standard way to access and manipulate message content, including headers, properties, and the message body, within various integration flow steps. This language uses a straightforward ${...} notation to dynamically retrieve values at runtime. For example, ${header.myHeader} accesses a message header named 'myHeader', and ${property.myProperty} accesses an exchange property.

A. JavaScript is a scripting language used within a dedicated Script step for complex transformations, not the standard expression language for component configuration.

B. "XML expression language" is not a standard term. While XPath is used specifically for navigating XML documents, Simple language is for general message access.

C. SAP Cloud Integration does not expose the Spring Expression Language (SpEL) for developers to use in integration flow components.

Cloud Integration: Define Message Headers and Exchange Properties. This document explicitly shows the use of Simple Expression Language for setting header and property values. It states

"You can use expressions to specify the value dynamically. The expression language supported is Camel Simple Expression Language."

In SAP API Management, an API provider represents the backend system that hosts the actual service or API. An API proxy is an intermediary layer created within the API Management platform. The primary function of the API proxy is to act as a facade for the backend service. It decouples the consumer-facing API from the backend implementation. When an API proxy is created, API Management generates a new, unique URL (the proxy endpoint) that consumers use. The proxy then forwards incoming requests to the target endpoint of the configured API provider.

A. The API provider manages secure API access for an API proxy.

This is incorrect. The API proxy, through the application of policies within API Management (e.g., Verify API Key, OAuth), is responsible for managing secure access, not the backend API provider.

C. The API provider provides a unique URL for an API proxy.

This reverses the relationship. The API Management platform generates the unique URL for the API proxy. The API provider simply has its own target URL that the proxy calls.

When testing a connection to an on-premise system via the Cloud Connector from SAP Cloud Integration, the Location ID is a mandatory parameter. The Location ID serves as a unique identifier for a specific Cloud Connector instance connected to an SAP BTP subaccount. This allows the SAP BTP connectivity service to route the test request to the correct Cloud Connector, especially in scenarios where multiple Cloud Connectors are connected to the same subaccount for high availability or to access different on-premise landscapes. The "Test Connectivity" tool in the monitoring section explicitly requires this parameter for the 'On-Premise' proxy type.

A. Connector ID: "Connector ID" is not the correct terminology for the parameter used in the Cloud Integration connectivity test tool. The official parameter name to identify the Cloud Connector instance is "Location ID".

B. Host: While the virtual host and port of the backend system are also required for the test (entered in the 'Address' field), the Location ID is the specific parameter that identifies the Cloud Connector itself, which is the connection provider.

D. Subaccount ID: The test is performed within the context of a specific SAP BTP subaccount where the Cloud Integration tenant is running. Therefore, the Subaccount ID is implicitly known and not a parameter you need to provide manually.

Performing Connectivity Tests:

In the section describing the HTTP connectivity test

the documentation states

"For the On-Premise proxy type

you also need to specify the location ID. The location ID identifies the Cloud Connector that is used for the connection to the on-premise system." This directly confirms that the Location ID is a required parameter for this specific function.

(Document: SAP Integration Suite > Operating and Monitoring > Monitoring Integration Content > Performing Connectivity Tests)

Cloud Connector

Initial Configuration:

The documentation defines the Location ID: "An optional

unique ID that identifies the Cloud Connector. It is used for routing purposes within a subaccount. For example

if you have two Cloud Connectors connected to the same subaccount

you can distinguish them using different location IDs." This explains the fundamental purpose of the Location ID in the BTP landscape.

The Open Connectors capability within SAP Integration Suite simplifies connectivity to third-party applications by providing harmonized RESTful APIs. These APIs are exposed as standard HTTPS endpoints. To consume these endpoints from an integration flow, it is mandatory to use an HTTP-based client. SAP Cloud Integration provides the dedicated OpenConnectors adapter for this purpose, which acts as a specialized HTTP client that handles the specific authentication and communication protocol required to interact with the Open Connectors service. The fundamental interaction pattern with Open Connectors is exclusively via HTTPS.

A. API Management capability within SAP Integration Suite: An integration flow can call an API Proxy using an HTTP client, but this is not the only interaction pattern. API Management can also be used to enforce policies on non-HTTP based services.

C. SAP Integration Suite, advanced event mesh: This is a message broker service for event-driven architectures. It is primarily accessed using messaging protocols and adapters like AMQP or JMS, not a generic HTTP client for its core functions.

D. SAP Business Application Studio: This is an Integrated Development Environment (IDE) for building applications. It is not a runtime service endpoint that an integration flow would call.

About Open Connectors: "Open Connectors simplifies and accelerates connectivity to third-party cloud applications by providing harmonized RESTful APIs and pre-built connectors." This establishes that the core offering is RESTful APIs

which are accessed via HTTP/S. (Source: SAP Integration Suite > Open Connectors > About Open Connectors).

OpenConnectors Adapter: "The OpenConnectors adapter allows you to connect to the APIs of the third-party cloud applications that you have connected in the Open Connectors capability of SAP Integration Suite."
