When you create a new report from OneStop Reporting, you select the company you want to use when building your report. However, you can change this in the Report Configuration dialog box.
In the Select data connection dialog box, in the Companies drop-down menu, you can select from the available companies.
If no connection has been configured, a connection must be created in the Get Data module in the OneStop Reporting portal. For information on how to create connections, see Create a connection.
