On many platforms, there is the box "Notification". The p-admin decides whether or not this box is available. If the box is activated, it is displayed at any time (except when an input mask is opened).
(1) Open the folder or service-filing for which you want to be notified.
(2) Click on "Notify me for..." in the box "Notification".
If you want to be notified about all changes, click on "Notify me for the whole platform".
If you want to make additional settings about the notifications, please visit the chapter Adapt your notifications in Settings
