Current User who's logged IN department ID tracking

Dear All

We are using PSFSCM 9-2 PT 8.53 and zero image update. The current user could be tracked by %operatorid is there any way to directly arrive at the department of the user who is currently logged in refer below screenshot

or if it's not possible current requestor by something like %requestor etc i.e. at run time is there any variable/expression value which could track the current user who is logged in DEPARTMENT ID or REQUESTOR ID or SHIP TO LOCATION or LOCATION as defined in the setup financial/supply chain -> common definitions -> user preferences -> define user preferences.
