Need DFFs fields for telnet screen for a PO receive

 Hi All

I have a requirement from a client where client will be migrating from non-WMS based environment to WMS based environment.  Currently in the forms of receipt creation they have some additional DFFs (like Truck Number, Truck carrier, etc) which are critical to business and are specific to a particular receipt number. 

I wanted to know whether in telnet screen I can map the form level DFFs with the DFF creation in the telnet screen.What is the process for doing it.
