I recommended using a ""DS"" warehouse but they didn't like having to receive in and allocate out every serial number. They will receive a file each night from either Ingram, Tech Data, or Synnex with the invoice data reflecting the quantity drop shipped. No sweat receiving it in to inventory but allocating on the so invoice is a huge project. They can have hundreds if serial numbers for one line item. It would be great if we could keep the serial numbers in ar history, list them on the invoice, but not have to allocate them out of inventory.
