C_CPI_2506 SAP Certified Associate - Integration Developer Questions and Answers

The “Open Integration” principle of SAP Integration Suite emphasizes openness beyond SAP-to-SAP integrations.

SAP provides pre-built content and adapters for SAP solutions (S/4HANA, SuccessFactors, Ariba, Concur, etc.).

Additionally, it supports third-party applications and ecosystems through:

Open Connectors (over 160+ third-party apps like Salesforce, HubSpot, Workday).

Open APIs and standards (REST, OData, SOAP, JMS, AMQP, etc.).

Thus, the principle ensures SAP + non-SAP integration scenarios are fully supported by default.

In SAP BTP, SAP Event Mesh provides messaging capabilities (queues, topics, and subscriptions) that require specific role collections to enable developers and administrators to perform tasks. SAP delivers two dedicated role collections for Event Mesh:

EventMeshDeveloper:

Manages queues and topic subscriptions

Monitors Event Mesh and its queues

Performs testing of queues and message flows

EventMeshAdmin:

Includes all developer capabilities

Provides additional administration rights for lifecycle management of Event Mesh instances and configurations

When a user is assigned these role collections, they gain the ability to:

Create and manage queues and topic subscriptions.

Monitor usage and resources such as queue depth, consumers, connections, and spool size within Event Mesh.

Other provided options are incorrect:

ApplicationAdmin/ApplicationDevelop → These are not SAP Event Mesh role collections, they do not provide queue or topic subscription access.

SecurityAdmin/SecurityDevelop → These roles are tied to security configurations and do not allow Event Mesh operations.

IntegrationAdmin/IntegrationDevelop → These roles belong to SAP Integration Suite (Cloud Integration) capability, not Event Mesh.

Therefore, the correct and verified answer according to SAP Integration Developer documentation is:

B. EventMeshAdmin and EventMeshDevelop

In SAP Event Mesh, topic subscriptions follow a defined hierarchical string structure:

Namespace → Defines the domain or context (e.g., sap/s4/beh/businesspartner).

Topic name → Specifies the exact event (e.g., BusinessPartner/Changed).

Separators (/) → Used to concatenate namespace and event details into a full subscription string.

Other options:

API key, Client ID, and Authentication token → Used for connectivity but not part of the topic string.

Business Partner ID, Change type, Event timestamp → Payload details, not part of the subscription string.

Source/Target system → Not required for constructing the topic name.

Thus, the correct components are Namespace, Topic name, Separator.

SAP Event Mesh supports two key asynchronous messaging patterns:

Publish/Subscribe → Producers publish an event once, multiple subscribers consume independently.

Point-to-Point (Queue-based) → Messages sent from one producer to a single consumer via a queue.

Other options are incorrect:

Request/Reply → Synchronous pattern, not the focus of Event Mesh.

Multicast messaging → Not explicitly supported; handled through Pub-Sub.

Thus, Event Mesh supports Publish/Subscribe and Point-to-Point messaging patterns.

For asynchronous processing in a SOAP adapter (SAP Cloud Integration):

Use Message Exchange Pattern = One-Way → Indicates no response is expected.

Choose Process Settings = Robust → Ensures message reliability and error handling in async flows.

Other combinations:

Request-Reply → Used for synchronous scenarios, not async.

WS Standard → Not the correct configuration for async reliability in CPI SOAP adapter.

Thus, correct async configuration is: One-Way + Robust.

For an asynchronous integration architecture, the best design pattern is Event-Driven Architecture (EDA):

Events (notifications) are published by producers and consumed by interested partners asynchronously.

Enables decoupled, scalable, and resilient communication.

Other options:

Serverless design → A runtime execution model, not a messaging pattern.

Request-driven design → Synchronous, not asynchronous.

Hexagonal design → A software architecture pattern, not messaging-driven.

Thus, for exchanging asynchronous notifications between partners, the correct design is Event-driven design.

To activate Event Mesh (EMIS) capability in SAP Integration Suite, the required role collections are:

Integration_Provisioner → Allows provisioning of new capabilities (including Event Mesh) in Integration Suite.

Subaccount Administrator → Grants permission to manage and configure subaccount-level entitlements and service activations.

Other options:

Integration_Administrator, API_Manager, Monitoring_Viewer → Used for operational tasks, not provisioning.

Process_orchestrator → Refers to on-premise PI/PO, not BTP roles.

Security_Auditor → Auditing role, not activation.

Thus, the correct roles are Integration_Provisioner and Subaccount Administrator.

When generating a Service Key for an SAP Integration Suite Event Mesh message client, the credentials contain details required for authentication and connection.

Event Mesh uses OAuth 2.0 client credential flow for secure access.

The Service Key includes:

Client ID

Client Secret

OAuth Token URL

These values are used by applications to authenticate and obtain tokens before accessing Event Mesh queues or topics.

Other methods (Basic Authentication, API Keys, X.509 certificates) are not used by default for Event Mesh service keys.

In Event-Driven Architecture, resilience is ensured by:

Loose coupling → Services do not depend on each other’s runtime availability. A failure in one service does not directly impact others.

This design minimizes cascading failures that can occur in tightly coupled systems.

Asynchronous communication and error handling help further, but loose coupling is the fundamental characteristic that limits failure propagation.

Incorrect options:

A → Robust error handling is important but not the main architectural limiter of cascading failures.

C → Centralized logging helps with troubleshooting, not failure prevention.

D → Asynchronous buffering mitigates impact but loose coupling fundamentally prevents direct propagation.

In SAP Cloud Integration, when defining Content Modifier properties, the Java data type names are case-sensitive.

Correct type → java.lang.String

In the configuration, java.lang.string was used (lowercase “s”), which causes a ClassNotFoundException, since Java cannot find the class.

Other options are correct in form:

Source Type = XPath → Valid.

Source Value = //ProductID → Valid XPath.

Name = ProductID → Valid.

Thus, the error occurred because of incorrect data type specification.

In SAP API Management, supported API description languages include:

RAML (RESTful API Modeling Language)

OpenAPI Specification (OAS, formerly Swagger)

Both are industry-standard languages for modeling REST APIs.

Other options:

A. HTML → A markup language for UI, not an API modeling language.

D. CXML (Commerce XML) → A B2B procurement standard, not for API modeling.

In SAP Integration Development, particularly when working with OData V2.0 interfaces, the correct way to identify the available entity sets is by retrieving the metadata document from the OData service. The metadata document, accessible via the $metadata endpoint of the OData service, provides a comprehensive description of the service's data model, including all entity sets, entity types, properties, associations, and navigation properties. This document is formatted in XML (CSDL - Conceptual Schema Definition Language) and is essential for understanding the structure and capabilities of the OData service.

Why Option B is Correct:

Metadata Document Role: The metadata document is a standard feature of OData V2.0 services, as defined by the OData protocol. It exposes the schema of the service, listing all entity sets and their properties. For example, accessing https:// /$metadata returns an XML document detailing the entity sets, such as Customers, Orders, or other resources exposed by the service.

SAP Reference: According to SAP documentation, such as the SAP Gateway Developer Guide and OData V2.0 Protocol Specification, the metadata document is the primary source for discovering the structure of an OData service. In SAP Gateway, which is commonly used for OData services in SAP environments, the $metadata endpoint is automatically generated when an OData service is created using the Service Builder (transaction SEGW).

Practical Usage: In SAP Integration Suite or SAP Cloud Integration, developers use the metadata document to configure integration flows (iFlows) that interact with OData services. Tools like SAP Business Application Studio or Eclipse with SAP plugins allow developers to import this metadata to generate client code or configure adapters.

Why Other Options are Incorrect:

A. Retrieve the service document from the interface: The service document (accessed via the root URL of the OData service, e.g., https:// /) provides a list of entity sets but only includes their names and URLs, not the detailed structure (e.g., properties, types, or relationships). While it’s useful for navigating to entity sets, it lacks the comprehensive schema information provided by the metadata document, making it insufficient for fully understanding the entity sets’ structure.

C. Search in the Global Directory of all available OData interfaces: There is no such thing as a "Global Directory" for OData interfaces in SAP or the broader OData ecosystem. OData services are specific to individual systems or applications, and their discovery is typically done via the service’s metadata or service document, not a centralized directory.

D. Contact the OData interface manufacturer: This option is not practical or standard. OData is a protocol, not a product with a "manufacturer." The metadata document is the standard, self-contained way to explore an OData service, and no external contact is required.

SAP Integration Developer Workflow Example:

Access the OData Service: In an SAP environment, an Integration Developer identifies the OData service URL (e.g., https:// :/sap/opu/odata/sap/).

Retrieve Metadata: Append / $metadata to the service URL to download the metadata XML. For example, https:// :/sap/opu/odata/sap/ZCUSTOMER_SRV/$metadata.

Analyze Entity Sets: Parse the elements in the metadata XML to identify available entity sets, their properties, and navigation paths.

Use in Integration: In SAP Cloud Integration, import the metadata into an iFlow’s OData adapter to configure operations like querying or updating specific entity sets.

In SAP Cloud Integration (part of Integration Suite), the Data Store operations allow temporary or persistent storage of messages for asynchronous processing or correlation.

WRITE → Used to save/store data (e.g., Customer ID) in the Data Store.

GET → Retrieves stored data.

SELECT → Reads stored data with filters.

POST → Not a valid Data Store operation in SAP CPI (it’s an HTTP verb).

Hence, to save a customer ID, the correct operation is WRITE.

In a microservices architecture, applications are decomposed into multiple smaller services communicating via APIs. This results in:

Increased API traffic due to inter-service communication.

Higher need for governance: enforcing policies, security, throttling, and quotas.

Comprehensive monitoring required to trace calls across multiple distributed services to ensure performance, reliability, and compliance.

SAP Integration Suite’s API Management provides these capabilities:

Traffic management (quotas, rate limiting).

Security policies (OAuth, API keys).

End-to-end monitoring & analytics for distributed calls.

Thus, the correct answer highlights the need for more robust API management and monitoring in high-volume, microservices-driven landscapes.

Key API Management components in SAP Integration Suite:

API Designer → Used to design APIs, import specifications (OpenAPI, RAML), and define metadata.

Product → Groups one or more APIs into a package that can be published to API Business Hub Enterprise.

Other options:

Authorization Server → Part of security infrastructure, not a direct API Management component.

API Entity → Not a defined component; the actual entities are API Proxies, Providers, and Products.

Thus, correct components are API Designer and Product.
