Accessibility in Web Applications 

Use

Accessibility means unrestricted access and working methods for physically impaired users of SAP systems. Accessibility is concerned with general system availability for special user groups such as blind, visually impaired, or mobility impaired users.

It also gives the physically impaired user the opportunity to personalize various system settings, such as the screen display, according to their own requirements.

Prerequisites

The generated HTML of BEx Web applications is adapted for output through electronic tools (assistive technology). Accessibility is possible only through the use of screen readers.

Procedure

General Accessibility Settings

BEx Web Applications support the use of assistive technology. Make sure parameter ACCESSIBILITY=X is set when you call your URL.

Additional Settings and Recommendations for Supporting Visually Impaired Users

When you create Web applications for visually impaired users, consider that data displayed in the form of charts and maps is very problematic. Therefore, display data for visually-impaired users in tabular form or at least give the option of changing from a graphical to a tabular display.

When using the ticker Web item, ensure that the ticker is set to an appropriate speed.

For visually-impaired users, SAP is providing two stylesheets with high contrasts (high contrast and high contrast black) that you can select in the Web application designer in the settings for your template.

You can change the font size in your browser settings, since the typeface in BI stylesheets is formatted relatively. When you adjust your stylesheet, ensure that you retain this formatting.
