LN Vendor Managed Inventory - Rosettanet Messaging

Good Day

I need to create/develop a Vendor Managed Inventory integration between an LN 10.2.1 instance and remote BAAN 4c4 instance.  The Infor LN User Guide for Vendor Managed Inventory (VMI) refers to a RosettaNet-XML message being sent between customer and supplier. However, it does not specify how this is achieved i.e. ION or some other method.

I have found very limited information regarding RosettaNet Enabling Kit for Baan IVc4 and nothing technical for LN other than the user guide mentioned earlier.   

If someone could point me in the right direction that would be great.
