Connect SAP ECC-R/3 and PostNL

Connecting SAP ECC-R/3 and PostNL for a company could allow for automated exchange of order, shipment, and tracking information. Such a connection could streamline logistics processes, reduce manual data entry, and improve the accuracy of delivery status updates by linking enterprise resource planning with shipping and delivery operations.

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

Why connect SAP ECC-R/3 and PostNL?

A company that operates both SAP ECC-R/3 and PostNL could benefit from connecting these systems to enable data exchange between their core enterprise resource planning functions and their logistics or shipping processes. Without such a connection, staff may need to enter the same information in both systems, which increases the risk of errors, delays, and inconsistencies. For example, customer addresses or order details could be entered differently in each system, leading to shipping mistakes or delays in order fulfillment. Records could diverge over time, making it difficult to track the status of shipments or reconcile financial data. This lack of synchronization could result in operational inefficiencies and decisions based on outdated or incomplete information. If a connection were established, it could enable the transfer of data such as sales orders, shipping addresses, tracking numbers, and delivery confirmations between SAP ECC-R/3 and PostNL. This could help ensure that shipment information in the logistics system matches the order data in the ERP, and that updates to shipment status are reflected in both places. The specific data that can be exchanged depends on what each system exposes through its API and is determined for each 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 PostNL 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.
