Abstract

This diploma thesis covers information system SAP R3 which dates in year 1972. During decades it has been improved and spread almost in all areas of data handling in companies. By help of different modules the system covers human resources, production planning, material management, plant maintenance, project system, etc. The basic navigations in SAP R3 run by help of shortcuts of programs, called transaction. The business applications of system are divided in standard and customer applications. Standard applications are complex, extensive and general thus for easier application usually customer programs are developed covering only smaller area of company’s needs. Thus, customer applications are easier to use for end-users. SAP R3 system has a special form of database consisting of a typical relational database on physical level and special data dictionary on application level. Main goal of data dictionary is consistency of different data types across the whole information system. Main part of this thesis is devoted to the development of new application for management of holiday facilities in company. First, old application and its database are analyzed then the new database model is defined on the basis of requirements. Special program was made to convert and transport data from old database model to new one. Development of new application starts with simple management of master data. Then special interface for the call for tenders was made that fills six tables with data, so user doesn’t have to. Manual application is possible but the real improvement is introduction of web application. Finally, planning of integration of SAP R3 and another system on example as mobile devices as another system is shown. Needed infrastructure is defined alongside the steps and data that are required on mobile devices. Concept of SAP R3 operating with mobile devices has a lot of potential in the future.
