Hello Suman,
could you please check if the otion create travel request, plan, ... are available in the SAP menu
(above the field where you can implement transaction codes- not visible on your screenshot).
If not- please change the persone number to your own. If transaction trip allows your perno to create busniess trips, trip request, plan - it's maybe a question of authorization. So check you profile via su01 especially for the objects F_TRAVL (Planning) and P_TRAVL (Travel Expenses) if you are allowed to process other perno's than yours (maybe it's limited to one company code or so)
