Project Overview

This project was delivered for a large automotive supplier with very strict requirements around information security governance and source control processes. The client outsourced internal logistics operations to an external provider and needed a reliable integration interface between the client’s SAP landscape and the external provider’s logistics software — supporting JIS (Just-in-Sequence) and JIT (Just-in-Time) logistics.

Our solution was based on the D4S platform and leveraged core PST-style integration and application capabilities. We integrated SAP, transformed SAP messages into the external provider’s message format, and ensured stable interoperability. To enable the project, multiple improvements were also required inside the client’s SAP processes and integration points.

The client operated 24/7 production, so availability and support were non-negotiable requirements.

Business Value

The solution enabled a stable, auditable, and scalable interface between SAP and an external logistics provider while maintaining continuous operations.

Key outcomes:

• Reliable interoperability between SAP and third-party logistics systems for JIS/JIT flows

• Reduced operational risk through monitoring, retrigger workflows, and transparent error handling

• Scalable architecture to handle 1M+ transactions per year

• 24/7 production support model with clear responsibilities and operational tooling

• Long-term stability through a 5-year support commitment
