Hi Karthik
In SAP Teched there was a good hands on workshop where this is covered using Xcelsius BO integration with solman
But if you want to use dashboards in Solution Manager and design of your own then you need to have knowledge of BI ....Solution Manager has inbuilt BW system so it is easy to copy or create a new infocube or a dashboard report as per your requirements
