Supplier is not able to see Affected object on supplier portal.

Hi - I created a problem report from PIM against an item. On the Problem report i can see the item against which i created the report on affected object tab. On security tab i gave access to a supplier user. I changed the status to "Open".

I logged in as supplier user to whom access was given, i can see the PR on supplier portal and can create Corrective action on supplier portal. But on the supplier portal when as a supplier user i am opening the PR, i can not see the affected object item. Is there any setup i am missing? Please guide.
