Some changes to project item requirements are introduced since AX 2012 R2.
Changes in AX 2012 R2
The Item requirements form moved from the Manage to the Plan tab in the ribbon.
You can create Sales orders of Order type Item requirements. As consequence, you can create as many Item requirements Sales orders as you want on the same project. Hence you could group your Item requirements based on Delivery date, and also if that group of item requirements changes of Delivery date, you can simply adapt it on the Sales order heading in stead of having to do it Order line by Order line.
Although you can create Sales orders of Order type Item requirements, you still can’t post the Packing Slip from the Project sales orders form: you still can only book it on the Item requirements form.
