My client links all sales order to production. Each sales order line has a promise date and ship date. The ship date is the date that production needs to be completed. They are using APS to schedule production which is properly using the ship date as the finish on constraint prior running the scheduling operations.

The issue is MRP is still using the ship date as the promise date resulting in a shortage of materials for scheduled production. How do we get MRP to look at the scheduled production to properly identify material requirements?
