I believe the "official" answer is you cannot have more than one data source per report.
Of course that does not mean you cannot. Construct a report with two sub reports. Sub report #1 has the report having data from data source #1, Sub report #2 has a report with data from data source #2. This means you do not violate the rules.
I have dozens of reports which use that methodology with success.
It is all a matter of perspective.

Hello Edd,
You can have one or many data sources in your report. For example if your report has 4 tables and 3 graph items you could have 7 data sources in a single report. So there is no restriction regarding that. Please also check the examples that get installed along with the product and are located in Start -> Telerik -> Reporting Q2 2013 -> Visual Studio 2010 Examples.
Regarding the calculations - a good approach would be to make the calculations outside of the report and then just pass the values to the report. Another approach would be to have a parameter for each data source (a hidden parameter). Then in each parameter calculate the exact same thing as you do in each table (or subreport). Then in a textbox in the report you can simply sum all parameters.
