Processing EMT Purchase Orders
A multilevel supply chain may use a combination of delivery methods to a customer. When this occurs, the EMT purchase order is referenced on the shipping documents, depending on the ship-to destination.
A sales order for a business unit that is at least two levels down may have three different purchase order references:
The purchase order from the previous level that drove the demand
The end customer’s purchase order
The purchase order for a ship-to destination
