SAP's Vendor Managed Inventory (VMI) functionality

Hello Friends,

Has anyone worked with or implemented SAP's Vendor Managed Inventory i.e. VMI functionality ?

I have read the 1. Help Documentation on the subject as well as 2. VMI Building Block Configuration Guide (Q38) for Best Practices. It appears to me that the Configuration Guide has more to do with the config that goes into the Vendor's SAP system.

1. Is there any document or steps that list the configuration for VMI from the customer's perspective ? To elaborate, if a new SAP customer implementing SAP ECC 6.0 wants to utilize the VMI functionality so that its vendors can plan and replenish materials on behalf of this customer, what are the necessary steps that need to be taken to implement this VMI functionality ?

2. SAP documentation assumes that both the customer and its vendors who plan the VMI use SAP ERP. In case the vendors have their own legacy or ERP systems, will the VMI functionality still work...since most data transfer happens via EDI ?

Any thoughts or suggestions are most welcome. Thanks for your inputs in advance.
