All features of the MQTT Adapter
Complete MQTT connectivity for SAP PO – from simple pub/sub integration to complex IoT scenarios with QoS guarantees.
Publish / Subscribe
SAP PO acts as publisher or subscriber on MQTT topics. Supports durable subscriptions and last retained messages.
- Wildcard subscriptions with # and +
- Durable subscriptions (persistent sessions)
- Last retained messages
- Multi-topic subscriptions
QoS Levels 0, 1 and 2
Full control over message reliability. Choose between at-most-once, at-least-once, and exactly-once depending on your use case.
- QoS 0: At most once (Fire and Forget)
- QoS 1: At least once (Acknowledged)
- QoS 2: Exactly once (Assured)
- Configurable per channel
Security & Authentication
Comprehensive security options for enterprise environments. All common MQTT authentication mechanisms are supported.
- TLS/SSL Encryption
- Username/Password Authentication
- Client Certificates
- SOCKS Proxy Support
Request / Reply Pattern
Synchronous and asynchronous request/reply communication without complex module configuration. Ideal for bidirectional IoT control scenarios.
- Async/Sync bridge integrated
- Correlation ID handling
- Timeout Configuration
- Response Topic Mapping
Payload Flexibility
Supports XML, JSON, and arbitrary binary payloads. Raw data from IoT sensors can be processed directly and transformed into SAP formats.
- XML, JSON, Binary Payloads
- Automatic Payload Transformation
- Custom Serializer/Deserializer
- Compression (GZIP)
SAP Cloud Connector & BTP
Seamless integration with SAP Cloud Connector for secure on-premise to cloud connections. Easy migration to SAP BTP and SAP Integration Suite.
- SAP Cloud Connector Support
- BTP / Integration Suite Ready
- Automatic Reconnect
- Migration Path from SAP PO

Frequently Asked Questions about the MQTT Adapter
What is the KaTe MQTT Adapter for SAP PO?
The KaTe MQTT Adapter for SAP PO enables seamless integration of SAP Process Orchestration with MQTT brokers. SAP PO can act as publisher or subscriber and process IoT data in real time. The adapter supports MQTT 3.1.1 and MQTT 5.0 according to OASIS standards.
Which MQTT versions are supported?
The adapter supports MQTT 3.1.1 and MQTT 5.0 according to OASIS standards. MQTT 5.0 offers extended features such as User Properties, Shared Subscriptions, Message Expiry, and improved error handling.
How is the security of MQTT connections ensured?
The adapter supports TLS/SSL encryption as well as all common MQTT authentication mechanisms. Additionally, usage via SAP Cloud Connector and SOCKS proxy is possible to establish secure connections from on-premise environments.
What are QoS levels and which are supported?
QoS (Quality of Service) defines the reliability of message delivery. The adapter supports all three QoS levels: QoS 0 (At most once), QoS 1 (At least once), and QoS 2 (Exactly once). This allows message delivery to be configured according to requirements.
Which IoT scenarios are typical for the MQTT Adapter?
Typical scenarios include: transmitting machine data from production plants to SAP PO, sending control commands from SAP PO to IoT devices, processing telemetry data from smart buildings, integrating mobile scenarios with MQTT-enabled devices, and embedding edge computing data into SAP processes.
Does the adapter support wildcard subscriptions?
Yes, the adapter supports wildcard subscriptions with MQTT standard wildcards # (multi-level) and + (single-level). This allows subscribing to multiple topics simultaneously without configuring each individually.
Can the MQTT Adapter be used for request/reply scenarios?
Yes, the adapter supports the request/reply pattern without complex module configuration. Synchronous and asynchronous bridges can be easily configured, significantly simplifying integration of SAP PO processes with MQTT-based services.
How does migration to SAP BTP/Integration Suite work?
The MQTT Adapter is available for SAP PO and SAP Integration Suite. Existing MQTT interfaces from SAP PO can be migrated to SAP Integration Suite with minimal effort. KaTe also offers migration consulting.
Which payload formats are supported?
The adapter supports XML, JSON, and arbitrary binary payloads. This enables processing of both structured data and raw data from IoT sensors.
Is the MQTT adapter suitable for production environments?
Yes, the adapter is designed for productive use and supports durable subscriptions, last retained messages, and automatic reconnect. A 30-day free trial allows evaluation in your own environment.
