Hi Sirkanth

The SAP Internet Transaction Server converts SAP R/3 screens into HTML format making it possible to access SAP systems with user-friendly Web technology. Through release 4.6DC4, 6.10 and today 6.20, a continuous improvement lifecycle, which includes additional functionality enhancement that streamlines and simplifies this process - SAP GUI for HTML.

SAP GUI for HTML automatically maps the screen elements in R/3 transactions to HTML using HTMLBusiness functions available within the SAP Internet Transaction Server. As a result, SAP Internet Transaction Server can dynamically generate an HTML version of an R/3 screen that is similar in layout.

Introduced with ITS 4.6C, also shipped with ITS 4.6DC4, 6.10 and 6.20, ITS Flow Logic is an implementation model for Internet applications that allows you to define the dialog flow outside the SAP system as flow logic. Applications developed using this model consist of linked HTML pages that can be populated with data retrieved from the SAP system or any other external system.

The main advantages of the flow logic model are

1. Its ability to support stateful and stateless applications,

2. Performance improvement, and

3. Easy modification of application dialog flow.

For example, stateless applications reduce the memory consumption of the application server, so that the overall application performance increases in comparison to the standard Web application model using R/3 transactions. Stateless function modules can also be called in any order, so the customer can easily change the dialog flow without making any changes to the R/3 application.

SAP Internet Transaction Server:

SAP Internet Transaction Server is the tool that enhances SAP’s highly scalable three-tier Client-Server architecture to the Web. It combines existing Internet technology with R/3 technology and allows reliable access to SAP functions from the Internet or Intranets.

Pls reward me Points if its helpful
