Unable to see PO in web UI for SNC

Hello,

I have the follwoing set up:

1. Business partner Vendor and Customer

2. Business partner Person for both Customer and Vendor

3. Assigned the persons to Business Partner Organizatio and also made them the Internet user.

4. Assigned ICH roles to the concerned persons

5. Business partner assigned to customer location(one of our plants)

6. Created partner dependant data for material I am buying from the supplier

7. Created TLane by CIF of Purchase Inforcords and added means of transport.

But when I log into the supplier view and search for the material or the purchase order I get a negative result. Please note that I have not done any changes to customizing other than Number range for Business Partner. Any idea what might have missed?

thanks in advance,

Subash
