ERP stands for Enterprise Resource Planning. The ERP is a data base containing all business processes, resources (labor, raw materials, goods, products, etc.) and all connections to the enterprise modules (procurement, production, sales, marketing, finance, etc.). Thus, planning or process changes are possible across all involved modules - from the top of the group, to centralized structures, to decentralized structures such as plants, external warehouses.
The best-known supplier of ERP software is certainly the Walldorf-based software company SAP.
