Never mind guys, I figured it out :)

Are you by chance importing serial numbers?  if so do you have scripting you can share?  we have a script for the so invoice but just added needing to be able to import serial numbers.

No, I'm not importing Serial numbers, but I am importing comments with the order items.  Here is an example of  adding comments:

retVal = oOrders.oLines.nAddLine()
retVal = oOrders.oLines.nSetValue("ItemCode$", "/C")
retVal = oOrders.oLines.nSetValue("CommentText$", SO.Notes)
retVal = oOrders.oLines.nWrite()

By the way my initial error was setting the KeyValue is zero filled.  Looks like this:

retVal = oOrders.nSetKeyValue("INVOICENO$", ZeroFillInv(SO.SONumber.ToString()))
retVal = oOrders.nSetKey()
retVal = oOrders.nSetValue("ARDivisionNo$", "00")
retVal = oOrders.nSetValue("CustomerNo$", SO.CustomerID)
retVal = oOrders.nSetValue("INVOICEDATE$", SageDate(SO.OrderDate))

thanks for sharing
