Linking Documents from the DMS 
Use
In the standard system, the notifications are linked to the SAP System’s Document Management System (DMS). This allows you to link documents that are stored in the DMS to a notification. You can display or print a linked document at any time while you are processing a notification.
Prerequisites
In Customizing for the notification type, a tab page has been activated for the DMS (see Customizing for Cross-Application Components under Notification
® Notification Creation ® Notification Type ® Define Screen Templates).Activities
To link a document contained in the DMS to a notification, you call up the notification in the create or change mode and then choose the DMS tab page. A table is displayed in which you can retrieve, link, and display documents from the DMS.
