Both ERP and MES are part of a company's production management system, but they serve different purposes. In the production management system, ERP primarily takes a financial perspective to set the direction for production management, focusing on the management of production plans and data. In contrast, MES, within the production management system, takes a manufacturing perspective to help workshops address specific issues related to products, equipment, and processes. Besides refining production plans and data, it also provides management functions for production control and scheduling.
