Case Study: Willi Hahn improves MRP and EDI-driven production planning with proALPHA ERP

Willi Hahn - Customer Case Study

Willi Hahn GmbH, a metal processing and automotive supplier, faced the challenge of replacing a heavily customized legacy ERP system that could no longer be updated. They required a future-proof solution to handle their complex operations, including managing a high-volume production of up to 280 million parts annually and integrating with about 40 different EDI partners, all while meeting stringent automotive industry IATF standards. The company selected proALPHA as their new ERP provider to act as both a solution provider and a development partner.

proALPHA implemented its comprehensive ERP system, which included modules for Profit Center Accounting, Business Intelligence, and an integrated Document Management System (DMS). The solution provided optimized resource planning for overlapping production stages and streamlined EDI integrations through a central converter. This resulted in significantly improved material requirements planning (MRP) efficiency and the ability to handle short-notice order changes from automotive customers. The new system provided a single platform for all locations, laid the foundation for further automation, and supported the company's consistent annual growth of over five percent.
