I would like to use the "Import records" function to import a list of Vendor bills, and use the Auto-Complete feature that available when manually creating the vendor bill using the user interface. 

I tried to use the column purchase_id/name (e.g.P00011), I tried using the field purchase_vendor_bill_id in my excel, but nothing seems to work. 

I cannot use bill lines, as for my "Vendor bill" I only have header information, I don't have the article details, quantities, prices from the invoice.

Anyone has a working example?
