Plan Data Collection not working for VMI

rHello Team,

We are trying to implement VMI (Vendor Manage Inventory) for Purchasing.

Following setups are done -

1) Purchasing --> Created BPA

2) Purchasing --> Approved Supplier Lists --> Setup VMI for Supplier

3) Inventory --> Item (Org level) --> Created Planner

4) Inventory --> Item (Org level) --> Setup for Purchasing tab and General Planning

5) ASCP --> Submitted Request Set (Planning Data Collection) --> But couldnt see anything extracted with this program

Can you please let us know if there is any specific parameters for Planning Data Collection so to collect data from Inventory.

Or could you please help us with the exact steps to implement the VMI.
