The interface of the SAP ERP connection system is implemented as a GUI to be driven in smartphones so that users can easily establish the part for interworking in the SAP ERP. The case described in this study is to provide communication for client applications and the SAP service through TCP/IP as a web service, and to implement a method of transferring server’s and client’s data request and result values in XML, to suggest a new method of efficient underworking of the SAP ERP. Keywords: ERP, SAP, Mobile, SmartPhone, SmartOffice, Platform 1. Introduction One of products generally used in the ERP (Enterprise Resource Planning) system is the ERP solution available from SAP. While services converged on communication and banking are vitalized by means of smartphones in the smart convergence environment, a new commercial transaction environment is rapidly growing, for example, non-financial institutions’ entry into the e-transaction market, sharply increasing mobile banking transactions, and increasing e-payment by means of mobile credit cards. The scale of Korea’s e-transactions in 2010 is approximately 824 trillion won in total, increased by 22.5% in comparison with approximately 672 trillion won in 2009. B2B which describes commerce transactions between businesses acounts for 746 trillion and 34.6 billion won in the total volume of transactions, and B2G which describes e-transactions for public sector marketing between the government and businesses accounts for 6.4%[1]. The concept of smart work is a future-oriented business environment in which people use IT technology to work conveniently and efficiently anytime and anywhere. The mobile office is for working without spacial limitations by using smartphones, PDAs, laptop computers, smart pads, etc., and is one type of services for providing a business environment through a mobile communication network and portable terminals, not just typically using an in-house radio network and laptop computers. It enables staffs to do office work in other places by accessing the in-house computer network, and to access the in-house system and data by externally using a security network in connection with the ERP and the CRM including e-mails, groupware and e-approval [2]. The Smart Revolution led by smartphones is changing the IT industry and the overall economic paradigm into the mobile era as well as ordinary daily living [3]. Large and medium-scale enterprises have already changed their PC and PDA-based system into a system fit for smartphones, and use the MEAP platform to develop products. However, the development by the MEAP platform requires a lot of costs to be connected with the SAP ERP system, and work forces to develop the products for smartphones. Small- and medium- scale enterprises which do not appreciate the importance of development do not want their system to be connected to smartphones in consideration of costs.
