At this stage BOM (Bill of Material), which is purchase order management that utilizes parts list management and parts development, was in the mail stream. And this concept (MRP) unfolded from order inventory management of material to plant and personnel planning and distribution\n planning, which in turn became MRP II (Manufacturing Resource Planning).This incorporated financial accounting, human resource management functions, distribution management functions and management accounting functions. It came to globally cover all areas of enterprise mainstay business and eventually came to be called ERP.
