Business partner and SNC Webportal screen

Dear friends,

1.Presently we could't find ''Business partner and user name'' fields in SNC web Portal screen.
2. We could't find ''Define new query, Change query and personalization'' displayed under PO work list in SNC supplier web Portal screen.
(Menu Path: Purchase Order > Purchase Order worklist)

Please can you share yout thoughts, if any activation's/configurations are missing to enable above fields.

Thanks
