By default, the Data Source Pane is displayed when opening the application. In case you closed it, it can be enabled from either the Home or the View Tabs. This menu will allow you to have direct access to your data source, so you will be able to include data points in your document template or to review and search through items for reference.

 

From the View Tab, check the box for Data Source in order to toggle the Data Source Pane on or off.
