ERP materials through the enterprise, capital, information and other resources of the unified management, and better information sharing, improve the utilization of enterprise resources to effectively strengthen enterprise management process supervision and control. ERP for inter-enterprise communications, EDI through the development of standardized data format for inter-enterprise system, eliminating the communication barrier. However, the exchange of information within the enterprise without a corresponding information standards. This problem in the enterprise integration or ERP system update is particularly evident.
At present the exchange of information at home and abroad due to the internal ERP is no corresponding standard, the different ERP software products are available in their respective data exchange methods, generally used to access the database directly or indirectly, the way to get the required data. This can speed up data processing speed. But in enterprises, integration or updating, especially in the face of a different ERP System, Different semantics and data structures may be an obstacle.
System Module
In the information process, some enterprises may exist at an early stage enterprise information technology personnel and the lack of computer equipment, etc., from the actual situation and cost considerations, often using only part of the ERP will be used to develop some modules or information systems, information technology comparison are ripe and then switch to the ERP system. Example, many enterprises of information technology is starting from the computerized accounting in the conditions are ripe, and then began to increase the module or directly on the ERP system. In the ERP system, the time is to choose a new system, or in the mature system to upgrade the enterprise are often faced with a question. To abandon the familiar system, and turn a new system for businesses is not only a great waste of resources, but also bear greater risks. In the selection system upgrades and add a new system module, we often face a problem is how to make the new system with the original system for smooth transition. Because different ERP systems may use completely different database systems and system processes, the database is not compatible, processes and so may result in differences in ERP implementation failure.
Integration of different systems
In an enterprise running different ERP systems are not very common, but the problem may be fatal. In the enterprise integration process, this situation may occur, often in joint enterprises are to be running a different ERP systems, so that often require ERP system integration. Because different companies may use different ERP software, and the larger size of the business the greater the difficulty in integrating the failure cases, the greater the losses. Because in reality, all enterprise information environment is different, if the ERP system integration, it might form two relatively independent of corporate information, it will form an "information island", so that each system is relatively independent and mutually closed. BenQ, Siemens mobile phone unit, the process of mergers, ERP integration failure is caused by the failure of an important reason for mergers.
EDI work patterns
The development process in the ERP, the enterprise had a single company to a supply chain, virtual enterprise-led development, inter-firm cooperation. In order to address inter-enterprise ERP system, the exchange of information between the early 60s in the last century, almost simultaneously in Europe and the United States put forward the concept of EDI. EDI (Electronic Data Interchange, Electronic Data Interchange) through computer communications network business information between enterprises, with an internationally recognized standard format, the achievement of the department or company and the exchange of data between enterprises and processing, and complete the trade as a Center for the whole process. International Organization for Standardization (ISO) will be EDI described as: "to trade (commercial) or administrative processing in accordance with recognized standards into a structured transaction or message data formats, from computer to computer, electronic transmission."
The early implementation of EDI systems are expensive, with the XML technologies emerge, the United Nations Center for Trade Facilitation and Electronic Commerce (UN / CEFACT) and the Higher Organization of American Structural Information Standards (OASIS) has also filed a ebXML (Electronic Business using eXtensible Markup Language) of the solution. ebXML as a low-cost EDI implementation technology has been rapid development.
