Designing a Web Form to Start a Task

Purpose

You want to design a Web form to start a workflow or task in the R/3 System.

Prerequisites

A namespace template and a development class must be defined in Customizing. To do so, carry out the activity Name range maintenance for task-related transactions in Customizing for SAP Business Workflow.

Process Flow

You define the workflow or task that is to be started by a Web form. If elements in the task container are to be filled with values from the form, they must be

Identified as import elements

Defined with a data type reference to an ABAP dictionary field.

Multiple-line elements or elements that reference an object or structure are not supported at present.

You then generate a Web transaction in the system that allows users to fill the import elements of the task container and start the task.

A Web transaction is an R/3 transaction that must be specially designed so that it can be called from an HTML page. The name of this transaction is generated and consists of the namespace template that you defined in Customizing and the task ID.

Following this, you develop an ITS service from this transaction in the SAP@Web Studio.

An ITS service essentially comprises an ITS service description, HTML templates (one for every screen in the R/3 transaction) and language-support files. The Studio is a development tool linked to the R/3 System that runs on your PC. The Studio assumes that the ABAP transaction already exists.
