I can’t see any way to do a Vendor Consignment Warehouse in AX 2012? Does that option exist or is it planed to anytime soon?
I do not think this function is standard available in Dynamics AX.
You can create also a new location called consignment and several warehouses used to keep the consignment separated from the other inventories. Apart from this if you are looking for a automate functionality then you would have to make a customization for it.
Any 3rd party tools exist?
