Because of its restriction, using the ERP on the market could be the "image of markets and buildings in mirage".I developed the ERP system software for the small and medium enterprise with and my classmates, and the paper is based on the EPR system. In the software development, my task is the design and implement of the manufacturing resources plan (MRP Ⅱ ) sub-system, which is a management information integrative system that is widely applied in all kinds of manufacturing industry. First, the paper simply introduced the ERP system, such as the ERP system's concept, development and application, essential management theory. Second, the paper introduced the characteristic of the small and medium enterprise and the MRP Ⅱ subsystem in a small and medium enterprise, according to analyzing requirement to users.In the basis of adequately comprehending theory and method of MRP Ⅱ application software, the writer discussed into the calculate way of MRP and CRP in small and medium enterprise and gave an example to explain it. Writer stressed to discuss the enactment the key data of the calculate way of MRP. And the author doesn't thinks that the leading time is fixed among them. The author thinks they should be calculated according to the quantity of the order, processing time, delivering time, preparing time, waiting for time and lining up time, what use quantity of the equipments in the routing etc.
