SAP Business Workflow via the Internet 
Use
Workflow functions can be called via a Web browser using an Internet Transaction Server (ITS).
This enables employees who seldom or never work with a SAP GUI for Windows to access workflow functions.
Integration
SAP provides not only the option of generating your own Web transactions, but also predefined Web scenarios known as Easy Web Transactions (EWTs).
Prerequisites
You need an ITS to work with Web integration. You also need the SAP@WebStudio.
Features
Integration of Web forms
SAP Business Workflow
Web integration supports starting workflows and executing work items.
An employee creates a notification of absence in a Web browser using a Web form. Either this process starts a workflow, or the workflow has already been started by the form being called.
The employee's superior then receives a work item in their Web workplace (a replication of their Business Workplace in the R/3 System), in which they can approve or reject the request.
The employee is informed of the result via their Web workplace, for example with a mail.
In both situations a Web transaction is generated from a task. These transactions must then be processed with the SAP@WebStudio. Finally, the service and HTML templates generated must be published on the relevant ITS. This is also done using the SAP@WebStudio.
The object type Form with method HtmlProcess is available for executing work items.
