When an org unit is selected (the row is highlighted yellow) you will be able to see if any objects are linked to the org unit by clicking the heading e.g. Customers.
Click the +Add button to select any new objects to be added - remember to click Save to keep the changes.
When creating or editing a User, Project etc, the drop down option will only allow you to add Org Units your own user account has access to, regardless of your profile so you may not see all org units set up.
Org Units are intended to restrict access. so if you need to see everything within your Company, your user needs to be added to all org units.
If no organizational unit is selected for a Resource or Project you may see this field show as "Public". This means there are no restrictions by org unit for visibility.
