Hi Joe,
Im new to the forum. I donot know if your question has been answered. But here's my view. The industry norm for calling up vendor while processing an invoice is machine generated sl no.The reason being that there will be no duplication of vendor numbers when they are machine-generated. And for your second question the answer is no, as a machine based serial number is unique with in-built controls and will not be used by any others as the "exclusive" locator for a venor.
