Hello Sangeeta,
No Problem. We are still facing the issue for pricing request. Anyway we completed rest all scenarios successfully. We entered negotiated price manually to complete rest of the scenarios and now are back looking into Pricing issue. We have print scenario also pending but now looking into request pricing from now.
Talking about the URL path we are using /cxf/COD/ERP/SALESORDERPRICING_REQUEST which is same as you mentioned. But we are still getting same issue which I shared before.
It seems Web Service call from COD is rejected to go out to HCI. Your kind help will be appreciated. 
Regards,
Chandan Bankar
