Does the order in which you set the datasources for a main report and its sub-reports matter? I am passing the populated DataSets of several business objects to a report and the data for the main report is not displaying. The sub-reports are displaying correctly.

I also tried setting the tables explicitly in the main report:

report.Database.Tables[0].SetDataSource(BillingTotal.DataSet.Tables[0]);
report.Database.Tables[1].SetDataSource(BillingTotal.DataSet.Tables[1]);
