Extended Notifications for SAP Business Workflow 
The enhanced notifications for SAP Business Workflow enable the user to be informed by e-mail or SMS about work items that require processing. Notifications are sent to the relevant user in the form of messages. At present, e-mail messages (HTML or text-only) and SMS messages are supported.
An e-mail notification can be:
A simple text which informs the user about work items in their SAP Workflow inbox that require processing
A descriptive text including links that enable you to display or execute a work item directly, or to display the Workflow inbox in the Web browser
A descriptive text including executable attachments that enable you to display or execute a work item directly, or to display the Workflow inbox in the SAP GUI.
An e-mail message can contain one or more notifications for work items. In addition, the message contains details about the sender and recipient and a subject, and may also contain some descriptive text. The following example shows a message with two notifications:
SMS
An SMS notification can be:
A general text which informs the user about work items in their SAP Workflow inbox that require processing (including system and client details)
The work item short text (including system and client details)
Integration
Front-End Applications
If a notification contains a URL or an attachment to either display or execute a work item directly, this is done in one of the following front-end applications:
SAP GUI for HTML, based on the Internet Transaction Server (ITS)
SAP GUI for HTML, based on the SAP Web Application Server (Web AS) Release 6.40 or higher
Web browser for work items that are based on Web technologies such as WebFlow Services, Business Server Pages (BSP), WebDynpro, and so on.
SAP GUI for Windows
Installation, Administration, and Configuration
If SAP GUI for windows is used for displaying and executing work items, then the standard installation of the SAP GUI for Windows is sufficient. No user-specific configuration settings need to be made in the client software.
The administrator can configure the notifications centrally by using a BSP-based administration application.
They can then configure their extensions by using a view cluster.
Single Sign-On
SAP recommends that you use Single Sign-On. If the message contains a link or an attachment for displaying or executing a work item, the user can navigate to the relevant SAP System without having to log on separately.
Groupware Support
The extended notifications for SAP Business Workflow enable you to use Groupware functions. For example, if you have Microsoft Office installed, the message is displayed in the default inbox. Any rules defined by the user also apply for the messages created for the Workflow. Furthermore, messages can also be sent to a dispatcher, which gives you access to additional Groupware functions. The dispatcher and additional Groupware functions are not supplied by SAP.
Constraints
The notifications sent are primarily messages and not work items. This means the following:
Messages remain in the user’s inbox after the corresponding work item has been executed and are not deleted automatically. However, the user can delete the messages manually.
New notifications for existing work items are not automatically created when changes are made that indirectly affect the assignment of work items. If new users are assigned to an organizational unit, no new notifications are created for any work items that already exist.
You can display and execute work items directly from an e-mail message, but it is not possible to replace or reserve them directly. However, the user can navigate from the view where the work item is displayed to the Workflow inbox and execute the function required there instead.
If an agent has defined a substitute, but substitution has not yet been activated, then the substitute does not receive any notifications. This also applies if the substitute has actively transferred the substitution himself.
At present, notifications cannot contain documents, such as Microsoft Word files, as attachments. Only the HTML format for Microsoft Outlook is supported for HTML messages at present. E-mail messages can only be sent to Internet e-mail addresses.
Submethods and advance with dialog are not supported for work items that call the SAP GUI for HTML.
Task-specific Groupware forms are not supported.
Extended notifications for SAP Business Workflow do not replace Microsoft Outlook Integration calendar synchronization. Furthermore, they do not replace the pure e-mail functions provided SAP MAPI (normal SAPoffice messages from the Documents folder are not forwarded).
