Create a report that's gives complete information about a mobile user and its call history. Report should have a parameter named 'MobileNumber'.By using this parameter, complete information should be displayed (e.g. Scheme name, CustomerName, Address, city, state, country, current balance, type of connection). Use a sub report over this parent report that gives call history report (e.g: Where he called, from where he got the calls, Transaction amount) that should be grouped by Year and Month. Also, in the sub report add a 3D cylindrical chart, that should be categorized by Year with transactional amount.
