Under the employee data collection contract you can manage the function for an employee.
If the function isn't listed or you want to describe it differently, you can go to "Attributes" in the left menu and manage the functions there.
You can add, edit, or delete functions.
If you're working with a (new) employee and the desired function isn't listed, click the gear icon (see image below). The function management page will open in a new tab, allowing you to add a new function to the system. You can then select it directly for the employee.
