Something to control, mainly on the operational procedures to control
According to 1978 Nobel laureate in economics, the United States, Professor Charlswood concept of "bounded rationality" theory, as long as the procedures are rational, process specifications, the results of rationality is the inevitable result of a rational process . System can be programmed through the following:

(1) Control of business operations. Transmission of information as clues to corporate rules and regulations as the standard will cost reimbursement, inventory management, product purchase and sale of the business processes which are often regulated, and through environmental settings, conditions, options, issues-driven and other software technologies to be embodied in the system in. In their daily business activities, the system will automatically reject non-compliant steps.

(2) Accounting system control. Can mainly be to take measures in the following areas: a. accounting subjects, by setting a name of the preparation, content integrity and simplified classification of accounts appropriate, standardized accounting processes, to facilitate the extraction of regulatory information; b. Financial Policy: by the system based on pre-set criteria, auto-complete provision for depreciation, amortization and other costs of the work to eliminate the use of relevant policies and man-made phenomenon of regulation of accounting profits; C. accounting statements: the use of taking the number of formulas generated directly from the accounting books of accounting statements, report data to ensure a true and complete.

To control things through the system, can effectively control the implementation process in the system, man-made factors have created a variety of arbitrary, fraudulent, improve internal control the stability and reliability.

3. Ex post facto control of the main in the system may take the following control measures

(1) Data checking. The system can automatically check the occurrence of internal and external data as well as the balance amount if they meet specified logical relationship, and to abnormal monitoring the timely submission to the relevant departments. Among them, the internal check is the reconciliation between the various subsystems, such as transactions recorded in the financial sector whether the money and sales departments to achieve sales in line, the financial sector stocks change hands whether the actual property management department in line out of storage, etc. and so on; external verification refers to the system data through the interface will be reconciliation with external data, such as through electronic collection and payment of bills check whether the funds business with the bank records.

(2) Risk assessment. According to enterprises are faced with various risks, such as the financing of risk, investment risk, operational risk, environmental risks, design risk model, and transformed into concrete projects and risk indicators of control. System on a regular basis to collect relevant data, based on risk models, enterprises are faced with the risk reduction into the situation, generate risk assessment report.

(3) The inspection program completion. System on a regular basis the actual performance of the enterprise as compared with planned objectives, analysis of the concrete progress of the work and its changing trend is to meet the requirements.

(4) The inspection system implementation. Through the collection and collation of staff daily operations, the system can be regular analysis of staff job content and whether it is normative behavior. As the ERP system implementation is built on the basis of good management and, therefore, companies must have a sound regulatory framework, including financial management, economic accounting, quality management, warehouse management, contract management, production management and other systems. In addition, we have a complete and accurate data, including the various fixed, warehouse records, production records, and all indications standards. ERP system implementation must be built on the basis of good management; the other hand, ERP systems the implementation of the basic work can also facilitate the further improvement of the management and improvement.

Ex post facto control through the system to ensure that inspection reports of objectivity, reliability, improve inspection efficiency and reduce inspection costs and help the enterprises to achieve the timely detection of the target and the system implementation process of the deviation.

ERP system has its inherent weaknesses. The main performance is less flexible system. ERP system should play a role in nature, resulting in benefits, companies must first conduct a Business Process Reengineering to management thought, management system and methods to adapt ERP model, which makes enterprise ERP system is unable to meet the needs of individual management, and with the management theory, computer technology, innovation and changing market, business processes are in a constant state of flux, ERP does not meet the dynamically changing business process requirements, must go through a difficult development and implementation of the second can be achieved. Rigidity of information systems and dynamic changing market frequent BPR as a pair of important contradictions.
