Ensuring Innovation and Continuity through SAP S/4HANA Upgrade for a Global Trading Company

A major engineering-oriented trading firm specializing in industrial machinery and plant engineering, headquartered in Japan, embarked on a mission to modernize its SAP landscape by upgrading from SAP S/4HANA 1809 FPS02 to S/4HANA 2023 FPS02. The organization relied heavily on SAP to support its complex operational ecosystem including finance, manufacturing, and supply chain management.

The company partnered with Eitekh to ensure a low-risk, high-performance upgrade that would prepare its enterprise architecture for future cloud integration and digital innovation.
