Hi,
How can you have 2 reference documents for one transaction ?
Even if you make PO optional in OMBW , you will need to enter PO number while creating reservation
and this field (PO #) will be in displayed MB1B while you are creating transfer wrf to reservation.
If you do not enter PO while creating reservation it will not be shown in MB1B, because one
transaction can not adopt two reference documents at a time
Thanks
