unit price is not getting defaulted on PO/PR

Hi Guru's

I trying to integrate Purchasing with Advance Pricing.

I followed several oracle posted documents(1101067.1) for PO integration with Advanced Pricing.

But still I am not able find the price list unit price defaulted on to Requisition or Purchase Order.

Following is the process I performed;

1) profles 'QP : Licensed for Product = Purchasing (site level)

              QP: Pricing Transaction Entity set to Procurement(site level)
                   QP: Source System Code =  Oracle Purchasing(i also tried with Oracle Pricing)

2) Created an Item using Purchasing Template(assigned to relevant organization)

3) Created Contract Purchase Agreement(got approved)

4) Created a sourcing rule for the item created in the step 2.
