there are 5 different MenuSuite objects in NAV 2009. Choose the COMPANY object, go to Design mode, add your customized object at a locaiton you want and then save the Company MenuSuite Object.
Now if you re-open your RTC, you should find your newly developed report there.
I will try what you suggest. I just want to ask you when I finish adding new menu suite as per your suggestion, how to configure it so that RTC load it by default?
