The Share tab on the Notebook screen is used to specify how a notebook record should be shared with other users and/or groups.
As stated earlier in the Notebook screen section of this document, when the Private check box is selected for a notebook record, only the created user and all other users for whom the Allow Viewing Private Notebook check box is selected on the Users screen can view (and edit) the record.
However, on a record-by-record basis, the Share tab on the Notebook screen provides the option for a user to ensure that notebook records are visible to other specific users or entire user groups in the system. On this tab, a user who has created or updated a notebook record may select either one or more user ID’s, or one or more user groups, with which the note should be shared.
Once a notebook record has been shared with another user, the shared record should then be visible and the Shared with Me check box (a protected field) on the notebook record view will be marked as selected.
