Internet Transaction Server (ITS) is a middleware component developed by SAP to connect SAP software with the internet. ITS can handle various web technologies and maps SAP architecture to the internet, allowing real-time integration of hosted data into SAP applications. ITS benefits from various SAP applications and simplifies communication between R/3 systems and the internet.
Developed by SAP, Internet Transaction Server (ITS) is a system application that marked the company’s first concerted effort to extend business applications to the Internet through a Web browser. This was accomplished by programming ITS to convert screens to of SAP software in HTML, thus allowing Internet-based technologies to interact with SAP software programs. Used as a middleware component, ITS allows a number of SAP programs within the R/3 group to access the Web. With the growing number of end customers increasingly relying on remote computing, ITS was developed to help those customers to meet their own needs. Designed to connect SAP with the global community via the Internet, the program has evolved to efficiently deliver SAP software to the Internet.
Internet Transaction Server can handle a variety of web technologies for accessing SAP applications. Using the SAP GUI interface, both Web Transaction and SAP GUI for HTML are two such options. Leveraging the RFC protocol, Web Reporting, WebRFC and ITS Flow Logic are three other options. Internet Applications Components is also an option that uses a templated layout. While each technology uses a different approach, ITS is able to communicate with each technology and transfer the resulting information to a web browser via ITS and a web server.
To simplify the explanation, Internet Transaction Server maps the SAP architecture to the Internet. Working from the internet, a user will interact with internet technology which in turn communicates with a web server. From there, the web server will interact with ITS to establish contact with the SAP system. ITS takes over from that point and works behind the scenes to pass the requested information to the web server and user. The ITS interaction results in an HTML page presented to the user for each transaction screen, embedding a template as changes are made.
Solving the problem with R/3 systems having technical difficulties communicating with the Internet, the Internet Transaction Server then connects the two systems. Therefore, ITS controls both the login procedure between the two systems and the flow of information, managing the information session. Considered a core component of the mySAP Group, ITS benefits from a number of SAP applications including, among others, SAP ERP, SAP Enterprise Buyer Professional (EBP) and SAP Supplier Relationship Management (SRM). For companies, the main benefit of ITS is the real-time integration of hosted data into SAP applications, without having to duplicate that data.
