Connect SAP ECC-R/3 and PostgreSQL

Connecting SAP ECC-R/3 and PostgreSQL for a company running both could allow data to be exchanged between the enterprise resource planning system and the database. This could support reporting, analytics, or archiving by making SAP data available in PostgreSQL for further processing or integration with other business applications.

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

Why connect SAP ECC-R/3 and PostgreSQL?

A company that operates both SAP ECC-R/3 and PostgreSQL could benefit from enabling data exchange between these systems. The main motivation would be to reduce manual data entry, minimize errors, and ensure that business decisions are based on the most current information available. Without such a connection, staff may need to enter the same records into both systems, which increases the risk of discrepancies and causes delays when data in one system does not match the other. This can lead to operational inefficiencies, such as relying on outdated figures for reporting or planning, and can also make it difficult to maintain a single source of truth for key business data. If a connection were established, the types of data that could be exchanged would depend on the company’s use cases. For example, transactional records, master data such as customer or supplier details, and inventory information are commonly exchanged between enterprise resource planning systems and databases. The goal would be to keep both systems synchronized so that updates in one are reflected in the other, reducing the risk of data drift and supporting more accurate analytics and reporting. What can actually be exchanged depends on what each system exposes through its API, and is determined per situation.

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 PostgreSQL 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.
