Earliest acceptable date (EAD) in fusion order management is just a placeholder date?

Summary:

Does EAD have any functionality in fusion OM? If yes kindly share the details.

i tried various permutations and combinations of EAD values on sales order and shipping it. Looks like EAD has no impact on sales order shipment. Kindly advice if it's a dummy place holder date or does it have any functionality associated?

Best regards
