An Internet service for an internal service request has the following components:

• Service file with ITS parameters
• HTML templates for the different processing modes in the request
• File with the language-dependent resources from the HTML template.

You can process Internet services in the SAP@Web-Studio, or in the Web Application Builder (access from Customizing for scenarios). However, compared with the Web Application Builder, the SAP@Web-Studio has several advantages (syntax check, an editor that is easy to use, clearer management for each of the components and several Internet services at the same time, and improved help functions). You can also switch between tools during processing. You can use the source control in the SAP@Web-Studio to check Internet services in and out of the SAP@Web-Studio.

For more information on adaptation tools, see the SAP Library under:

In an Internet service, you need the following parameters for an internal service request:

When you start the internal service request, you call up the QISR1 transaction in the SAP System (SAPLQISR3 program). This goes to one of the following screens, regardless of processing mode: For each of these subscreen containers, you can define your own HTML template to generate the corresponding HTML form:

All HTML templates should be assigned to Default-Theme 99. You can leave out the HTML template for processing modes that you do not require.

If you do not require any variants for the request for the different processing modes, define the HTML template for the display mode. You can enter the following HTML business statement for all other HTML templates:

This statement ensures that for each HTML template, the saplqisr3_110.html HTML template for the create mode is referenced.
In the HTML template for creating, if you use the functions from the ISR-HTML library (for SAP Design) or from the ISR-Plain-HTML-Library (for Plain HTML), then the entry fields are automatically switched to Not ready for input depending on the processing mode.

The simplest HTML template contains the HTML code for displaying the request in the web browser. You can embed the HTML business statement into the HTML template for a dynamic HTML page layout.
For more information on HTMLBusiness, see the SAP@Web-Studio or the Web Application Builder under Application Help. You can use HTML business to create HTML statements under certain circumstances for example (if ( ... ) ... else ... end;) or in loops (for ... ;). In the HTML template, the following generally applies:

You can also refer to data from the SAP R/3 System in the HTML template, using HTML business. For example, the

statement means that the BUILDING_TO characteristic is output in the HTML page that was created using the template.

As well as the special characteristics defined in Customizing for scenarios, you can use the following general data from the internal service request in the HTML template.

The following functions are available in the SAP General HTML-Business-Functions Library to enable you to create the most important form elements (buttons, fields, labels etc.) quickly and easily:
