User Group Configuration for Note Types determines access to Note Types for User Groups.
Note:
When a Note Type is created, the User Group that created the note is automatically assigned full rights (Create, View, Modify, Delete) to that Note Type. Only the owner of a note, or a member of the Manager or Administrator groups can delete a note from a document. Delete privileges for Note Types do not apply to notes created by other users.
Note:
See Note Type Security for additional information on levels of security for notes.
