Connect SAP ECC-R/3 and as2

Connecting SAP ECC-R/3 and as2 for a company could enable the transfer of business documents such as purchase orders, invoices, or shipping notices between the ERP environment and external trading partners. Such a connection could support automated data exchange, reduce manual entry, and help maintain data consistency across business processes.

You can build this integration on the System2System platform. We design the connection between SAP ECC-R/3 and as2 around the way you work — not as an off-the-shelf connector, but to fit your systems.

Why connect SAP ECC-R/3 and as2?

A company operating both SAP ECC-R/3 and as2 could benefit from connecting these systems to enable more efficient and accurate data exchange. Without such a connection, staff may need to manually re-enter information from one system into the other, which can lead to duplicate data entry and increase the risk of errors. Over time, records in each system could drift apart, resulting in inconsistencies that make it difficult to rely on either system for up-to-date information. This situation could cause managers to make decisions based on outdated or incomplete data. If a connection were established, it could allow for the transfer of business-critical data such as purchase orders, invoices, shipment notifications, or inventory updates, depending on what each system is designed to handle. In the case of SAP ECC-R/3, it is widely known to manage core business processes like finance, logistics, and supply chain operations. as2 is a protocol used for secure and reliable exchange of electronic data, often in the context of EDI transactions between business partners. The kinds of data exchanged between these two could include structured business documents required for supply chain and financial operations. Ultimately, the specific data that can be exchanged depends on what each system exposes through its API and must be determined on a case-by-case basis.

How System2System builds an integration

Connectors

We connect to each system through the interface it offers — an API, a database, a file exchange or a webhook — and handle authentication, rate limits and retries.

Mapping

Fields rarely line up one to one. We map and transform the data so both systems receive it in the shape they expect.

Workflow

We define what triggers an exchange, in which direction data flows and which system takes precedence when the two disagree.

Monitoring

Every exchange is logged. Failures are flagged and can be replayed, so nothing disappears without anyone noticing.

What can actually be exchanged?

That depends on what SAP ECC-R/3 and as2 make available through their APIs, on the licences and modules in use, and on the version each system runs. Which records are synchronised, in which direction and how often, is something we determine together before any work starts.

We are happy to look at your specific situation and tell you what is feasible — including when the answer is that it is not.
