To better support ERP system and PDM system integration for independent enterprise network manufacturing system,the characteristics of ERP and PDM integration were analyzed and the technology of business remote function call was presented.The standard or custom functions which supporting remote transfer through BRFC interface could be called by the ERP or PDM systems to gain data which would be used to achieve the integration.Not only was a kind of integration model of ERP and PDM composed,but also the BRFC interface was described semantically.And the structure,realization and interview of remote function call technology which was used by ERP and PDM integration was researched.Also,data exchange of system integration based on data stream direction was discussed to ensure self-containment,collaboration,recombination and unsustainably of the ERP and PDM systems integration for network manufacturing.The conception of heterogeneous data translator was put forward,and its data structure was given.Interface development tools provided by ERP or PDM were given full considerations.And the system composing mode was construed clearly.The heterogeneous data translator was applied to realize classic code system,system information searches of PDM,system information searches of ERP and integration information searches.Then the advantages of BRFC were expounded.Finally,an application example of typical integration of WLPDM and SAP R/3 ERP in WLNM networked manufacturing platform was presented to verify the feasibility and efficiency of RFC technology.As a result,seamless integration,plain integration,non-repeated data memory,integration flexibility and low cost were realized.
