MQTT Adapter for SAP PO

MQTT Adapter for SAP PO

MQTT Adapter for SAP PO

The Internet of Things (IoT) is the communication and networking of real objects via the Internet. In addition to devices such as computers, smartphones and tablets, more and more objects from the “offline world” are joining them, such as cars, televisions, wristwatches, heaters, weather stations and household appliances.

The KaTe MQTT Adapter for SAP PO connects your SAP system landscape, i.e. SAP Process Integration & SAP Process Orchestration with the Internet of Things.

The KaTe MQTT Adapter is also available for SAP CPI (Cloud Platform Integration) or SAP HCI.

KaTe MQTT Adapter

Message Queueing Telemetry Transport (MQTT) is an open standard for lightweight message transfer between devices, sensors, and applications with high latencies and deployment in low-bandwidth networks.

SAP PI – Process Integration

SAP Process Integration is SAP’s Enterprise Service Bus (ESB) solution for A2A and B2B scenarios, offering a wide range of adapters and integration tools (e.g. transformation, orchestration, routing, reliable messaging and monitoring). SAP Process Orchestration 7.31 additionally provides numerous BPM functions and a rules engine.

MQTT – Message Queue Telemetry Transport

Message Queueing Telemetry Transport (MQTT) is an open standard for lightweight message transfer between devices, sensors, and applications with high latencies and deployment in low-bandwidth networks.

The MQTT protocol has been standardized by Oasis as the “Internet of Things” protocol since 2013. In addition to its traditional use in sensor networks, connected manufacturing and home automation, MQTT is also increasingly used in mobile scenarios (e.g. in Facebook Messenger).

Core technical functions of the KaTe MQTT Adapters

  • Fully compatible with the MQTT v3.1 and MQTT 5 Standard.
  • Publish/Subscribe to MQTT topics with wildcards, durable subscriptions and last retained Messages.
  • Use of common messaging patterns like pub/sub and request/reply without complicated module configuration (ex. async/sync bridge).
  • By using the Adapter Framework, full support of SAP PI tools (design, configuration, monitoring).
  • Connects to MQTT brokers
    direct, via Socks Proxy or SAP Cloud Connector On premise

KaTe MQTT Adapter Features

  • The KaTe MQTT Adapter is easy to implement.
  • The KaTe MQTT Adapter implements publish/subscribe patterns and enables true push messaging between participants.
  • Various Quality of Service levels for data transmission in unstable networks, such as mobile networks, are handled by the KaTe adapter.
  • The protocol overhead for this adapter is very small.
  • Ideally, meta information only needs to be transferred once, since the server continues to hold the data after a connection is lost.
  • With the KaTe MQTT adapter, data can be transmitted in any possible format.

The history of MQTT

The MQTT protocol has gained a lot of popularity in recent years. MQTT was programmed in 1999 by Andy Stanford-Clark (IBM) and Arlen Nipper (Cirrus Link) for monitoring oil and gas pipelines. Transmitting data via satellite has always been very costly and therefore a smart solution was sought. The Message Queue Telemetry Transport, or MQTT, protocol which was developed in this manner fulfilled the required characteristics. Following this project, MQTT was used and further developed as a proprietary protocol at IBM in a variety of projects. In 2010, the MQTT specification was released to the public and since then a large infrastructure has developed around it.

Use Cases:

API-First Development: Bridging Old and New Worlds

Software development is increasingly shifting to mobile platforms, hyperscalers, or container environments, all of which leverage the Open API Standard for API management, security (JWT, OAuth2), and automation.

The KaTe RESTful Adapter facilitates seamless SAP integration with API-first strategies from non-SAP ecosystems—whether on SAP BTP, hyperscalers like AWS, Azure, or GCP, or in containerized development environments.

Open APIs in regulated industries

Regulated industries such as telecommunications (TMF), banking (Open Banking), or utilities (market data exchange) require standardized Open APIs for data exchange. Our approach significantly reduces the development and operational costs of such APIs while leveraging existing developer skills and requiring minimal investment.

The KaTe RESTful Adapter maximizes the efficiency and security of your API integrations, protects existing investments, and builds seamless bridges between SAP and modern API standards. With this future-proof solution, you are well-equipped to meet the increasing demands of integrating advanced technologies and driving your digital transformation forward—enhancing your SAP landscape to its full potential

Use OData within established architectures

SAP has strongly committed to OData, which can be described via Open API definitions. However, challenges often arise in hybrid environments or API management solutions:

  • SAP Specifics: Clients need to manage XCSRF tokens or deal with SAP-specific attributes in OData definitions.
  • Internal Links: API management solutions may return responses with internal links, creating security risks and hindering OData clients from working directly.

The KaTe RESTful Adapter resolves these issues efficiently: Links are automatically rewritten to frontend URLs, and XCSRF tokens are handled automatically.
