Developing an ITS Service from a Transaction (SAP Library - BC - SAP Business Workflow

Developing an ITS Service from a Transaction

Prerequisites

You have created a Web transaction from a task, as described in the previous steps.

You know the task and the name of the transaction with the associated module pool. If you do not know the transaction and module pool, you can find out their names from the Repository Browser in the ABAP Workbench.

You have installed the SAP@WebStudio.

Procedure

The SAP@Web Studio contains separate documentation on using the Studio. For this reason, only information relevant to this scenario will be provided here.

Launch the SAP@Web Studio.

Create a project to store your ITS components.

Define a service for this project. Use the Service Wizard for this purpose.

Enter the name of the transaction as the Service Name.

Enter the name of the system in which the task is defined and other logon information.

Select Use Diag-Channel on the dialog box and enter the name of the transaction.

Every ITS service based on a service description, in which, for example, the R/3 System and the transaction to be used are determined. Every service description is in its own service file.

For each ITS there is also a global service description that contains the standard settings for all ITS services. These settings can be modified and/or overwritten by the individual service descriptions.

Each service description is in its own service file (ASCII file ending in srvc ) in the file system of the ITS computer. The HTML ^Business-templates that are needed for the Web transaction (HTML files with specific placeholders for R/3 data) are also located there.

The SAP@Web Studio allows the user to create and maintain service descriptions and HTML^Business-templates.

Create the HTML templates for the Web transaction. Use the Template Wizard for this purpose.

Enter the name of the module pool for the transaction in the Program field.

Enter 50;100;150;200 in the Screen number field.

Enter the name of the service created in Step 3 (name of the transaction) in the Service field.

Enter the 99 as the theme.

One Theme is a logical name for the optical appearance of a web transaction. The name consists of two characters (letters or numbers). In principle, as many Themes as you like can be used for a web transaction. The Theme should always be set to 99 for Web forms.

The Studio creates an HTML template file on your PC for every screen in the transaction. The name of this file appears in the object list for the service. To display the HTML source code, double-click the name of the template.

Revise the HTML templates. For more information, see Extending HTML templates.

Define an ITS site for the system, if you have not already done so.

Transfer your ITS files to the ITS site (publish function).

Result

All of the files required by this service have been copied to your ITS server and, therefore, can be called when necessary.
