Application Development: Main Steps

Purpose

This process describes the main steps you have to take in the SAP@Web Studio to develop applications that are driven by the Internet Transaction Server (ITS).

Prerequisites

You have installed the SAP@Web Studio.

You have defined the business logic in the R/3 System:

If you are developing a screen-dependent application based on Web Transactions, you have created a dialog transaction

You must do this first, because you need to be able to specify the underlying ABAP program and screen numbers when creating HTML templates.

Nota

This documentation describes how to use the functions of the SAP@Web Studio.

For a step-by-step introduction to developing screen-dependent applications based on Web Transactions using the SAP@Web Studio, see the Web Transaction Tutorial.

If you are developing a screen-independent application based on ITS Flow Logic, you have developed a set of Business APIs (BAPIs) or remote-enabled function modules (RFCs)

In this case, it is not essential to define the business logic first, but it makes sense to follow the procedure described in this documentation.

Process Flow

To develop an ITS-driven application that accesses data in the R/3 System and can be run from a Web browser, you must create an ITS service.

The procedures below describe how to:

Create a new service
Change an existing service

Creating a New Service

Start the SAP@Web Studio.

If you are starting the SAP@Web Studio for the first time, set up the environment.

Create a new project to store the service directories and files.

You can assign several services to one project.

Define an ITS site.

Create the required ITS files:

Create the service file.

If you are developing a screen-based application driven by a Web-enabled R/3 transaction, create the service file with the service wizard

If you are developing a screen-independent application based on ITS Flow Logic, create the service file manually

Create the HTML templates.

If you are developing a screen-based application driven by a Web-enabled R/3 transaction, create the HTML templates with the template wizard

If you are developing a screen-independent application based on ITS Flow Logic, create the HTML templates manually

If you are developing a screen-independent application based on ITS Flow Logic, create flow files as necessary for the HTML templates.

If you want to keep your HTML templates language-independent, create language resources.

If you are developing a screen-based application driven by a Web-enabled R/3 transaction, create the language resources with the resource wizard

If you are developing a screen-independent application based on ITS Flow Logic, create the language resources manually

If you want to create instances of the same service with identical functionality but a different look and feel, create themes for the service.

Edit the files as necessary and perform a syntax check.

Publish and test the service.

Source-control the new files in the R/3 System:

Add the files to the R/3 Repository.

Create a change request in the R/3 System.

Assign the files to the change request.

Changing an Existing Service

Start the SAP@Web Studio and, if necessary, adjust the environment.

Open an existing project.

Select an existing ITS site.

Import the existing files.

You can import files from an ITS site or check them out of the R/3 Repository.

If you check them out of the R/3 Repository, they must be assigned to a change request.

Edit the files as necessary and perform a syntax check.

Publish and test the service.

If you previously checked the files out of the R/3 Repository, check them back in.

Result

You can start the new or changed application from any Web browser.
