Schedule Arrival Date = Schedule Ship Date + Delivery Lead Time

Request Date Type - Possible values are arrival and ship. If the value is arrival then the request date and promise date will be considered arrival dates by the system; if the value is ship then it will be considered ship dates. The request date type can be defaulted from the customer information to the order, and the user can change it on the order if required.

If you set the Order Date Type = Arrival in the header, and you will be able to update the Schedule Arrival Date ,

but  when you try to update the Schedule Ship Date  with the Availability , will get the below error.

“The order date type is "Arrival", Schedule ship date can't be manually changed. Schedule ship date can be recalculated if you change request date or schedule arrival date.”
