Item Standard Pack differences

We are using 9.2 and demand driven sales orders.

When a standard pack changes for item, and there is an existing sales order line for that item that already has recommended standard packs, our users will get a new shipment number to pull in the updated item standard packs on the item.

We have a situation where the user did NOT get a new shipment number, so even though the item standard pack set up was updated, the existing sales order line and its ASN were not.

Is there an edit anywhere in the order process that would validate that the recommended standard packs are still valid and notify if not?
