What causes this issue?

The assumed goods receipt date '&V1&', used to determine the quantity
schedule line from the assigned purchase order item, is either:
- The delivery date (LIKP-LFDAT), if the delivery note is created
without posting a goods issue and no actual goods issue date is
entered.
- The actual goods issue date (LIKP-WADAT_IST), if one 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.

System Response

The system does not accept the assignment of this purchase order item.
