Any assignment is shown to your driver, your assistant or your supplier only at the time of sharing. As long as it is not shared, you have the possibility to work on it as you wish without anyone else knowing anything.
Open the Agenda or one of the Schedulers from the calendar icon in the main menu.
Select the period to be taken into consideration and click on the menu item Share assignment.
At the top, select Suppliers or Human resources, depending on the assignments you want to share.
To change the time period, use the Filter on start and finish date.
View all the bookings involved which are still to be shared, grouped by start date. Select the ones that interest you and click on the Share button at the top.
To make the shares happen automatically at the same time as the assignment, go to the Preferences in the Agenda menu and select Automatic sharing for human resources, suppliers or both.
