Janan,
Download these SCs from SAP Marketplace, add them to the NWDI CMS inbox, check them in and then import them into your Development and Consolidation tabs.
You also need to resolve the SP issue with SAPPCUI_GP. You could get basis to deploy it to the portals via JSPM. Since both ESS and MSS use SAPPCUI_GP, it may be a good idea to backup the portals first and then test these applications to ensure that everything is still working.
Make sure that your NWDS is also on 7.02 SP 11.
