A user-specific quality notification is one that does not belong to one of the standard notification types predefined in the QM component.
You can create user-specific notifications:
To handle the types of problems that cannot be processed adequately using one of the predefined notification types
If you want to evaluate the data for user-specific notification types separately
A user-specific notification type has the same basic structure as the standard, predefined notification types. The screen layouts, reference objects, and tab indexes, however, may differ from those in the predefined notification types, depending on how you customize the user-specific notification type.
