Please do not apply form D for PZ071-00A02-2G or VN first because supplier did mention that form D not yet ready for VN and cannot apply for 2G because cosignee system is only VN.
So I feel that even you apply for PZ071-00A02-2G, cosignee would not be able to use the form D to clear for the part number of PZ071-00A02-VN.
