Currency from address book - does not carry to PO

We have a vendor set up with EUR currency.  Our company is in USD.  When I enter a PO from the P4310 - the program will use the currency set up in the address book, so the vendor will get a EUR purchase order.  When I enter a purchase order from the Capital Asset Parts Detail program (P17730), I call the same version of the P4310, but the currency will come over in USD, not EUR, so the PO prints incorrectly.

Is there a process option or setting to make sure to use the currency from the address book of the vendor?
