without posting a goods issue and no actual goods issue date is
entered.

Note: If you do not specify this and a goods issue is being posted,
then the system automatically enters this as the current date.
The date assumed for the goods receipt date, '&V1&', is outside the
range of the quantity schedule for the assigned purchase order item.
