@rambalaji , you are most likely in suitescript territory. Looks like you may have to create one or more custom suitelets for your users to interact with, and possibly map/reduce or scheduled scripts to do the 'back-end' work. I'd direct you to search the Netsuite help pages for "N/search", "N/record" "N/https", "N/task", "N/ui/ServerWidget" and "N/url".
