The diary can be filtered by user groups. A user group is a group in which users can be organised. For example, you could have a service group where all of the engineers within this group carry out service jobs.

How to filter the diary by user groups:
Go to your diary from the navigation bar.
On the right of the screen, you will be presented with a number of options.
