Application Of The Internal Control In ERP System Construction Of Petrochina

With development of information technology and information tide, China National Petroleum Corporation as an internationally competitive multinational group must keep the pace of development of information technology to build a strong platform for enterprise information technology support. Therefore, the China National Petroleum Corporation take the ERP system as hard core in the overall planning of information technology, However, the ERP system is a risky investment, implementation of ERP will be at risk. We should avoid it in face of risk first. If the risk is unavoidable, then we could analyze the possible sources of the risk and try to forecast it for reducing the risks.The issue analyzed in this paper are as follows: the implementation of the ERP project will bring the risk of the China National Petroleum Corporation and changes from the source to prevent and respond to changes in these risks, the successful implementation of ERP projects, the use of the internal controls applied to the ERP system in an effort to use the existing more mature risk management system of the China National Petroleum Corporation, design a set of internal control procedures of ERP system. Internal control procedures of ERP system includs project preparation, blueprint design, system configuration, testing and inspection, process improvement, on-line approval of six stages. The specific content of each stage, the focus and each stage of the work are described in this paper. After successful implementation of internal control procedures of ERP systems, the specific results come into being in the construction of Petrochina information systems, business process architecture, business risks, control measures, etc.In the ERP system construction of Petrochina, through the effective implementation of internal control procedures ,the project risks and potential changes in the ERP system are avoided and reduced and the blueprint of the ERP system is ensured to consists with the actual system configuration and business processes .At the same time, blueprint information and business processes become perfect, systemic risk are be prevented and the ERP project implementation get ahead finally.
