The following section describes how to select a data source. The procedure for selecting the data source for your report depends on the template you select. If you select a template that does not include a data set, Report Studio prompts you to select an information object or a data object stored in the iHub volume. If you choose a cross tab template, you must select a data object that contains a cube or a data model.
