SAP BTP Connectivity

SAP BTP Connectivity is a development skill for configuring cloud-to-on-premise system integration, covering connection management, destination setup, and secure data exchange

What Is This?

Overview

SAP BTP Connectivity enables seamless communication between SAP Business Technology Platform (BTP) cloud applications and on-premise systems. It provides a secure bridge for data exchange, allowing cloud-based solutions to access legacy systems without exposing them directly to the internet. The connectivity framework handles authentication, encryption, and routing automatically, ensuring that sensitive data remains protected during transit.

This skill covers establishing connections through SAP Cloud Connector, configuring destinations, managing credentials, and implementing secure protocols. You will learn to set up both HTTP and RFC connections, handle proxy configurations, and troubleshoot connectivity issues between cloud and on-premise environments. The framework also supports advanced features such as principal propagation, which allows user identities to be securely transferred from the cloud to on-premise systems, maintaining end-to-end security and auditability.

Who Should Use This

Cloud architects, integration developers, and SAP system administrators managing hybrid environments should master this skill. Anyone building cloud applications that need access to on-premise SAP systems will benefit from understanding connectivity patterns and best practices. Additionally, IT security professionals responsible for safeguarding enterprise data flows, and DevOps engineers tasked with maintaining continuous integration and deployment pipelines involving SAP systems, will find this skill essential for ensuring secure and reliable operations.

Why Use It?

Problems It Solves

Organizations running hybrid SAP landscapes need secure ways to connect cloud applications with on-premise systems. Manual connectivity setup is error-prone and time-consuming. Without proper configuration, you risk security vulnerabilities, data loss, or failed integrations. This skill eliminates guesswork by providing structured approaches to establishing reliable connections, reducing the risk of misconfiguration and ensuring compliance with corporate security policies.

Core Highlights

Cloud Connector acts as a reverse proxy, enabling secure outbound connections from BTP to on-premise systems without requiring inbound firewall modifications. Destinations abstract connection details, allowing applications to reference connections by name rather than managing credentials directly. SAP BTP provides built-in encryption and authentication mechanisms that comply with enterprise security standards. Connection pooling and load balancing optimize performance for high-volume data exchanges. The platform also supports monitoring and logging of connectivity events, aiding in troubleshooting and compliance auditing.

How to Use It?

Basic Usage

To configure a destination for an on-premise system, you typically define it in the SAP BTP cockpit or via API:

POST /destination-configuration/v1/destinations
{
  "Name": "OnPremiseERP",
  "Type": "HTTP",
  "URL": "http://erp-system:8000",
  "Authentication": "BasicAuthentication",
  "User": "sap_user",
  "Password": "encrypted_password"
}

This configuration allows your cloud application to reference the destination by name, abstracting away sensitive connection details.

Real-World Examples

Example one shows configuring an HTTP destination for accessing on-premise OData services. Your cloud application retrieves this destination configuration and uses it to make authenticated requests to the backend system without hardcoding credentials, ensuring both security and maintainability.

GET /destination-configuration/v1/destinations/OnPremiseERP
Authorization: Bearer token
Accept: application/json

Example two demonstrates RFC connectivity for calling ABAP function modules. The Cloud Connector translates RFC calls from your cloud application into on-premise system calls, maintaining protocol compatibility and security.

var destination = destinations.getDestination("OnPremiseERP");
var client = destination.createRFCClient();
var result = client.call("Z_GET_SALES_DATA", params);

Advanced Tips

Use destination certificates and mutual TLS authentication for maximum security in production environments. Implement connection pooling and caching strategies to reduce latency and improve throughput for frequently accessed on-premise systems. Leverage principal propagation to maintain user context across system boundaries, and use SAP BTP’s monitoring tools to track connection health and performance metrics.

When to Use It?

Use Cases

Migrating legacy applications to the cloud while maintaining connections to on-premise ERP systems requires robust connectivity setup. Building real-time dashboards that pull data from multiple on-premise SAP systems demands secure, efficient connections. Extending on-premise systems with cloud-based analytics and machine learning services needs reliable data pipelines. Implementing hybrid workflows that span cloud and on-premise processes requires seamless system integration. Additionally, scenarios involving regulatory compliance or data residency requirements benefit from the controlled and auditable connectivity provided by SAP BTP.

SAP Cloud Connector, SAP Integration Suite, and OAuth 2.0 authentication patterns complement this skill for comprehensive integration solutions. Understanding SAP Destination Service, SAP API Management, and secure network architecture further enhances your ability to design robust hybrid landscapes.

Important Notes

Requirements

SAP BTP subscription with Cloud Connector installed in your on-premise network. Valid credentials for both cloud and on-premise systems. Network access between Cloud Connector and on-premise systems. Administrative access to configure destinations and manage security certificates.

Usage Recommendations

• Always configure destinations using secure authentication methods such as OAuth2 or mutual TLS, especially for production environments.
• Regularly update and rotate credentials and certificates stored in the destination configuration to minimize security risks.
• Use descriptive and consistent naming conventions for destinations to simplify maintenance and troubleshooting across multiple applications.
• Monitor connectivity logs and set up alerts for failed connection attempts or unusual activity to quickly identify and resolve issues.
• Test connectivity configurations in a staging environment before deploying changes to production to prevent disruptions to critical business processes.

Limitations

• Does not support direct inbound connections from external cloud services to on-premise systems; all access must be initiated from the cloud side via the Cloud Connector.
• Limited to protocols supported by SAP BTP and Cloud Connector (primarily HTTP(S) and RFC), restricting integration with systems using unsupported protocols.
• Network or firewall misconfigurations between Cloud Connector and on-premise systems can cause connectivity failures that are not always easily diagnosable from the BTP side.
• Principal propagation requires compatible configuration across all involved systems and may not be available for all authentication scenarios.
