Can I use two datasets as setdatasources to a crystalreport

Question

Dear all,

I am having the two different tables attached to a crystal report using Database Expert.
I am getting the data from both the reports.

Now in the reportviewer i am using the code like this

billingreport.setdatasource(sa)
CrystalReportViewer1.ReportSource = billing
billinreport.setdatasource(sa2)
CrystalReportViewer1.ReportSource = billing;

 

Can i set Datasources as above?

 

Please suggest me
