New DC delivery date not synchronized with allocation table &1, item &2

What causes this issue?

Follow-on documents already exist for allocation table &V1& for
recipients.
Follow-on documents exist when there are stock transport orders or when
the purchase order in question is a direct delivery order.
In this case, synchronization is not executed between the allocation
table and the purchase order, despite the fact that distribution center
delivery dates were changed in the purchase order.

System Response

The system did not synchronize the changed DC delivery dates for the
purchase order &V3& in allocation table &V1&.
This may mean that the delivery cannot adhere to the "Goods Receipt
Recipient" date because of the change to the "Goods Receipt DC" date in
the purchase order.

How to fix this error?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Procedure for System Administrators

In this case, it is not possible to change the distribution center
delivery date in allocation table &V1& at a later date.
