Where can I find the RefNo in iif file for Vendor Bills

I am able to import a bill successfully, the issue I am having is the RefNo which is the invoice number does not show up. I used different variations for the heading such as TRNSrefno, RefNo, RefNu so far its still showing blank. another issue is that the vendor address doesnt show up, its not a new vendor. Do I have to have the address in the iif file?
thanks
