Internet Transaction Server / SAP@Web Studio (BC-FES-ITS)

Main processing component of the Internet Transaction Server (ITS).

The AGate (application gateway) links the ITS to the R/3 System. It receives Web browser requests from the WGate (Web gateway) through the Web server and communicates with the R/3 application server using the DIAG or RFC protocol.

When the AGate receives requests, it processes them, and sends all the details to the R/3 System, which either starts the first dialog step of a new transaction or submits further data for the next dialog step of a transaction already in progress. When a dialog step has finished, the AGate retrieves the result from R/3, processes it, and sends the response back to the WGate as an HTML page.
