URG: Items LOV on iSupplier > Product tab is null

Hi,

We want to implement iSupplier module for our client and while doing some testing, we observed that the Item LOV on iSupplier Portal Full access Responsibility  > Products tab is always shows Null.

FYI: We have all the ASL setup done at Commodity level and not at the Item level.

Can you please suggest how to get the Items in the LOV or is there a way to search based on commodity codes from iSupplier portal.

Thanks

Aneel
