How to use the ReportDataSource in a report viewer control

Hi I am using a reportviewer control in visual studio 2012 and I want to reset the datasource of the report viewer, but I can't figure out the right name value combination:
The Datasource in my .rdlc is "RF" and the Dataset in the .rdlc is "dsTotalOrderCalls"
I have an Objectdatasource ID:  "odsSales" and a type name:  "RapidFire.RFTableAdapters.USP_TOTAL_ORDERCALLSTableAdapter"
that is referring to a table adeapter in an .xsd (dataset) that is calling a stored procedure called "USP_TOTAL_ORDERCALLS"  and returning a data table called:  "USP_TOTAL_ORDERCALLSDataTable"

When I try to open a new instance of the reportdatasource ie,
rv_SalesSC.LocalReport.DataSources.Add(new ReportDataSource("dsTotalOrdersCalls", odsSalesSC));

I receive an error message saying:
Cannot create a connection to data source 'RF'

Can someone help me understand what values go into instantiating a new reportdatasource object?
Thank you!!!

my stored proc was producing an error based on the parameters I was sending it, I was able to instantiate the object using: rv_SalesSC.LocalReport.DataSources.Add(new ReportDataSource("dsTotalOrdersCalls", odsSalesSC)); which is the name of my .rdlc dataset and the ObjectDataSource ID value
