In this integration usage, EAM uses the purchasing system residing in an ERP application for the procurement of MRO materials and services, while EAM manages the MRO warehouses quantities and transactions (part issues, part returns, etc.). The integration allows the business processes of requisition, purchasing, inventory transactions, and payables regarding MRO materials and services to run across EAM and ERP applications facilitated by the Infor ION® environment.
