Hi Venkat,
It is not recommended to use Recent Items in CRM IC WebClient business roles as there is high risk to mix up data from different customer interactions as they are not cleared on pressing END button.
For CRM 7.0 EHP3 a new function has been delivered which allows to display the activity cliboard directly in the navigation bar profil, see SAP Note 2039600, my blog http://scn.sap.com/community/crm/interaction-center/blog/2014/09/16/tracking-customer-interactions-a-new-feature-and-end-is-your-friend for further information.
Best Regards,
Sigrid
