Event Add-on for ERP: connect SAP to Advanced Event Mesh.

Advanced Event Mesh (AEM) is an enterprise event broker and messaging service based on pub/sub architecture. It decouples producers from consumers: a system publishes an event once and all interested subscribers receive it independently. SAP Integration Suite, Cloud Integration (iFlow-based) is an orchestration and transformation layer – typically polling APIs or waiting for triggered calls. AEM and Cloud Integration are complementary: AEM handles real-time event distribution at scale, while Cloud Integration handles downstream routing, enrichment and transformation. Many customers use both together.

If you need a solution for customizable payload, event filtering, the option for batch loads as well as real-time loads, the Event Add-on for ERP fills this gap: it installs directly on your SAP ABAP system and captures business events – purchase orders, goods movements, financial postings and change documents – and publishes them to AEM in real time, without any custom ABAP development. It is the official bridge between your ABAP landscape and the event mesh.

The Event Add-on for ERP (component ASAAEMEE) is the SAP OEM edition of the ASAPIO Integration Add-on, bundled specifically for Advanced Event Mesh. It requires the base ASAPIO Integration Add-on (ASANWEE) and adds the AEM-specific transport component on top. Commercially, the Event Add-on for ERP is ordered via SAP Discovery Center and covered by SAP terms. The ASAPIO Integration Add-on is available directly from ASAPIO and supports a broader range of target systems (Azure, Kafka, AWS, Solace, Google, StreamSets and more). Technically, both components share the same ASAPIO core.

Any SAP NetWeaver ABAP system on SAP ECC 6.0 EhP 6 or higher, SAP S/4HANA On-Premise, SAP S/4HANA Private Cloud Edition, SAP BW, SAP HCM and other NetWeaver-based systems. See Minimum Requirements for detailed version information. Both HANA and AnyDB databases are supported. The add-on is not compatible with SAP Business ByDesign, SAP Business One or other non-ABAP platforms.

Yes. Advanced Event Mesh is a BTP service, so you need an active SAP BTP subaccount or subscription with CPEA, BTPEA, subscription or pay-as-you-go credits. The Event Add-on for ERP installs on your SAP ABAP system on-premise or in private cloud, but it communicates with the AEM broker that runs on BTP. The AEM broker is licensed separately via SAP using the "Connections" metric.

Yes. The Event Add-on for ERP supports bidirectional communication. Outbound: SAP publishes CloudEvents to AEM in real time. Inbound: external systems publish messages to AEM topics and the add-on subscribes and writes data back into SAP using standard integration methods. This enables end-to-end workflows – for example, a delivery confirmation from a logistics partner that lands directly in SAP as a goods receipt.

Yes, and this is a common production pattern. The Event Add-on for ERP handles the SAP ABAP-side event capture and publishes structured messages to AEM. SAP Integration Suite, Cloud Integration iFlows can subscribe to those AEM topics and perform downstream routing, format transformation or delivery to external APIs. Neither product replaces the other: AEM excels at high-throughput, low-latency event distribution; Cloud Integration excels at complex orchestration and protocol mediation.
