Does anyone know how to backdate a Request for Quote's Bid Close Date? I'm having difficulties in testing RFQs because the Bid Close Date cannot be earlier than the day you create the transaction, which means that you can only award it to a vendor(complete the transaction) the NEXT DAY at the earliest.

Maybe do a CSV import to update the record with scripting/workflows turned off? warning* I have never tried to do something like this myself on a record like this - this could result in errors any time someone needs to edit the record.
