Dynamics AX 2012 Available-to-Promise (ATP): Are You Using It to Full Effect?
Available-to-promise (ATP) is a simple calculation meant to provide a customer with a promise date for delivery. The business model is Make-to-Stock. This means that we have inventory on the shelf based on a forecast or a safety stock.
We typically use automatic reservation in Microsoft Dynamics AX so we do not run the risk of selling the same inventory twice. Nowadays we can control the automatic reservation in the Item Model group.
If we create a sales line for a quantity that we do not have in stock and we have automatic reservation, we will get the shortage window that allows us to look up on-hand in other sites or other companies.
