Requested delivery date of the document

Dear Team,

Can you please clarify the role of requested delivery date on the sales order header. It does not look as though the system takes this date into account on delivery creation. Is there a way to make this relevant so deliveries cannot be created until the requested delivery date arrives?

. I was attempting to see if there was any way to make sure the field is actually used properly - availability check should not allow items to be delivered before the requested delivery date. These orders come in through EDI, so there is no human intervention once they are entered.
