Here is an old tutorial on how to manually create a Production Order in D365 F&O. It also tells you why you SHOULD NOT be creating manual orders in a mature system.
This was production order was made at the beginning of our D365 journey and follow on Business Process creation changed some of the time scales and the order of things to follow. Items to consider when watching this video:
- MRP now runs every day, and with planning optimization multiple times a day (1:35)
- Our firming horizon changes based on the season and the scarcity of work. (2:34)
- Warehouse waves are done in daily blocks now not weekly (3:01)
