You download and install it from SAP.

It's then a matter of adding the correct references to the dll from that download to your project.
It uses odbc to connect to a database by default.
I usually create a temporary table or stored procedure to build a report against.
It needs something to give it a list of fields and types to work on.
I don't use odbc live because it's inefficient and a nuisance to maintain the dsn etc.
At run time I go get the data and provide it as a datatable or collection for the report.
rd = new ReportDocument();
rd.Load("whatever.rpt"));
rd.SetDataSource(dt);
rd.Refresh();
Where dt is a datatable with the same fields of the same type as the report was built against.
It can actually have more fields in it, all the report cares about is that when it goes and looks for a field it expects to find, it's there and it's a matching type.
