Research On Enterprise SAP Platform Interface Application Technology

SAP (Systems Applications and Products in Data Processing) is a system management software, put the computer technology and business management in the field of business processes together. However, relevant information about business processes can not be shared between the SAP system and external application systems, forming islands of information one after another. To solve this problem, this article from the perspective of practical application conducted in-depth research, the main work is as follows:Firstly, On the whole, it gives the background of theoretical knowledge of SAP systems, including SAP system software and hardware architecture and development platform, application delivery and execution policy.Secondly, RFC (Remote Function Call) interface technology, remote function call, through it remote landed from one SAP system terminal to another SAP system terminal, this interface technology widely used in transmission systems and Solution Manager configuration.Thirdly, BAPI (Business Application Programming Interface) interface technology, in the upper end of the RFC communication protocol, is a function interface of the SAP system comes with the business object-oriented, and it is capable of directly processed SAP business objects. This interface technology is greater frequency of used in large quantities of data import and external application system calling SAP system.Fourth, ALE-Idoc interface technology (Application Link and Enabling-Intermediate Document), is a distribution/integrated interface implementation of SAP systems, this technique is suitable for data exchange between different SAP systems within the enterprise. Because it does not require additional separate development program, the system can be achieved as long as the correct settings, so in practical applications are rare.Fifth, Web service interface technology, is the most widely and higher frequency used in SAP system at the present stage, is determined by its independence of development platform and language. Its biggest advantage is the ability to integrate existing various types of heterogeneous platform into a common middleware technology layers with independence of development platform and language. Between enterprises and enterprise heterogeneous application platforms use this interface to achieve interconnection and integration, effective solution to the problem of data sharing and interaction.Sixth, conductinig a deeper study to web service interface technology, first of all, introduction of trusted computing, namely the concept of integrity,combining with critical path concepts in engineering,proposing a determing algorithm of critical path of web service interface call based on integrity algorithm innovatively. Netxt,proposing a deteming algorithm of shortest path of web service interface call based on Qos(Quality of Service). Both methods have greatly improved the efficiency of web service interface call.
