Designing a Web Form to Process a Work Item

Purpose

You want to design a Web form to process a work item.

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 a standard task that is to be executed as a Web form. This task must reference the HTMLProcess method of the FORM object type. The elements in the task container that are to appear and be processed on the form must be

Identified as export elements

Defined with a data type reference to a DDIC field.

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

The elements in the task container that are only to be displayed on the form must be

Identified as import elements

Defined with a data type reference to a DDIC field.

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

You use this standard task in an activity in a workflow definition. Here, you must define the binding between the elements in the task container and the corresponding elements in the workflow container.

You can then generate a Web transaction from the task in order to execute the task, that is, that processes the export elements of the task container or displays the import elements.

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@WebStudio.

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 and that you want to create (or change) the ITS service components.
