Show tickets where a person attribute is the same as the logged in person in a single view

Case: we want a view that shows all open tickets of all users, based on a person's attribute (like department).

TicketStatus=Open
RequestedForExtraFields=PORDepartment==$person_PORDepartment$

Where $person_Department$ is the extra person fieldname (surrounded by $-signs) that has to contain identical values for both requestor/requestedfor and the person looking at the view. Please note that you need to identify on which field you want to filter, followed by the value to verify against, split by ==.
