SAP cares about the needs of its customers and communities and is committed in making its products more accessible to people with disabilities.
As mentioned above, accessibility is a top priority for SAP. This priority has been transformed in several areas within SAP, such as establishment of the SAP Accessibility Team, the creation of the SAP internal accessibility standard, the establishment of a test factory, and so forth.
SAP cares for the needs of its customers, including the customers who are strongly interested in the area of Accessibility and even make use of the accessible information and technology products in their working environment. As a result SAP also shares the same passion and vision that is to provide accessible products to our customers. This passion and vision has been transformed to the establishment of the SAP Accessibility team in Walldorf with various roles:
There is a prerequisite set of front-end requirements and settings required in order to work in the accessibility mode within SAP's solutions. In this section, you will find the required front-end requirements and infrastructure for Accessibility:
The document of Front-end Requirements and Infrastructure for Accessibility can be found on the SAP Design Guild (page SAP and Accessibility) at http://www.sapdesignguild.org/resources/acc_technical_requirements_external_EN.pdf

The ISO/IEC 17050 standard "Conformity assessment - Supplier's Declaration of Conformity" is an internationally agreed standard which defines the process and best practice that can be applied in all business sectors in all countries. The Information Technology Industry Council (ITI) and U.S. General Services Administration (GSA) partnered together to develop a standardized Supplier's Declaration of Conformity (SDoC), the so called VPAT. This is an official format which is used as well by other companies to declare the accessibility status of a product. It is based on the US section 508 and is SAP’s only means of communicating the status of its products to the customer. The VPAT is a legally binding document and the status reported in this document is reflected from the test results of our extensive testing process. Being aware of the needs of the European customers, SAP plans to provide as well product status documents based on WCAG. The WCAG product status documents will be provided not only for the web-based products but also for the non web-based products as long as the requirements are applicable. Since these product status documents are still in progress, please expect delay. To get more information about VPATs, please go to the following link: http://www.sapdesignguild.org/editions/edition9/vpat.asp
According to the World Health Organization (WHO), there were between 500 and 700 million people with disabilities worldwide in 2006. On top of this, there were around 600 million people aged 60 and over in 2000, some of whom might become disabled due to aging. The WHO forecasts that this sector of the world population will grow to 1.2 billion by 2025 and to 2 billion by 2050. In view of the sheer numbers of people affected by disabilities worldwide, considerable efforts have to be made at both the national and international level to address the challenges they face. As a result, awareness of the legitimate demands of older people and people with disabilities to take an active part in everyday life is no longer confined to interest groups, consumer organizations, and the public sector, but also has consequences for the actions of business enterprises. The private sector has recognized the economic importance of this ever increasing market segment and is becoming increasingly conscious of the requirements of this group of users.
There is a growing global awareness of the requirements of people with disabilities and older people, but this does not mean that all countries have a shared or even similar perception of the concept of accessibility. Some countries impose stricter laws and regulations, while some are less rigid. Some countries place a greater focus on the actual implementation of accessibility than others. The following section takes a brief look at how accessibility is perceived in a few selected countries.
This country takes a strict stand when it comes to providing accessibility to people with disabilities. The US was the first country to put accessibility legislation (Section 508 of the Rehabilitation Act) in place to elimininate barriers in information and communication technology products and open up new opportunities for people with disabilities. Basically, Section 508 dictates that all US federal agencies must provide federal employees and members of the public with disabilities with equivalent access to information. More information about Section 508 is available at www.section508.gov/index.cfm?FuseAction=Content&ID=14.
In Great Britain and Northern Ireland (the United Kingdom), the scope of accessibility has been widened by several amendments to the Disability Discrimination Act (DDA) and now applies to people considered as disabled in the areas of education and transportation. It is now the task of providers to make “reasonable adjustments” in these areas to remove any barriers that could disadvantage people with disabilities compared with people without disabilities (www.drc-gb.org/the_law/legislation__codes__regulation/dda_and_related_statutes.aspx).
In Germany and Austria, the concept of accessibility does not just refer to products in information and communication technology, but also concerns "products" such as buildings or transportation. Section 4 of the German Act on Equal Opportunities for Disabled People (BGG) defines accessibility as follows: "Buildings and other installations, transportation, technical devices, information technology systems, acoustic and visual sources of information and communication installations, and other structured areas of life are accessible if they can be accessed and used by people with disabilities as intended, without significant difficulty, and unaided."
The corresponding Federal Act on Equal Opportunities for Disabled People in Austria (BGStG) is formulated in a similar way (Section 6, No. 5 of the BGStG).
In other words, Germany and Austria define accessibility as the ability of people with disabilities to access tangible and intangible objects or information and technology products without any assistance. The German BGG and the Austrian BGStG are addressed primarily at federal agencies. For more information about legislation in Germany, read Section 2.2.4 or visit www.gesetze-im-internet.de/bgg/__4.html; information about legislation in Austria is available at www.parlament.gv.at/pls/portal/docs/page/PG/DE/XXII/I/I_00836/fname_036804.pdf.
Legal requirements form the basis for the practical implementation of accessibility. Legislative competence rests in the sovereignty of each state, and if different states introduce different accessibility regulations, this can cause problems for enterprise software that is used around the world. If regulations differ from country to country or even contradict each other, a company must decide which regulations have priority for its software. Global companies – like SAP – support moves toward the harmonization of legislation in order to avoid this situation, since it is not possible to fulfill all accessibility legislation in all countries.
The development of accessible software at SAP is based on clearly defined requirements and processes, as described in the internal SAP Accessibility Standard. These standards were first introduced in 2002 and, as well as including the requirements from Section 508 of the US Rehabilitation Act, also incorporate requirements from WCAG 1.0 of the World Wide Web Consortium (W3C) and International Organization for Standardization (ISO) 9241-171.
Establishing our standard as a central principle for all development activities at SAP presented us with the following challenges:
The requirements in the standards are organized into the following categories:
Note that the version of the SAP Accessibility Standard described in this book refers to Version 1.0 of the WCAG, since Version 2.0 was not available at the earlier press time.
In the following you will exemplary find the requirements in the category “Navigation and Keyboard Access”.
1. Keyboard Access
It must be possible to access all elements on a screen and to activate their associated functions using a keyboard.
2. Logical Order of Tab Chain and Reading Order
All UI elements must be included in the tab chain in a logical order. The tab chain is also determined by the reading order (such as left to right, and top to bottom). This general rule can be broken if the application requires a different tab order design for reasons of efficiency.
Note the following information about tab chains:
In the following cases, exceptions are acceptable:
3. Visible Focus
The current focus must be visible as it moves between the interactive UI elements during user navigation.
4. Skip Option for Large Elements
The user must be able to skip any large UI elements or grouping elements (such as a tree, data table, group box, menu area, or control).
