In this video I do a basic walk through of receipting a purchase order with the new WMS capabilities in AX2012 R3. This shows a basic use directed put away so you could get a sense for the flow in a WMS scenario where the warehouse floor workers have control over where they move stock and how that is managed.
The RF menu items that you see in this walk through are configured in the WMS module and from there you can define if a function is user directed or systems directed.
