# Changing an Endeca component's data source

If more than one data source has been configured for the application, the data source for an individual portlet instance can be changed.

To change the data source for an Endeca component that can be bound to a data source:

1. In the header of the component whose data source you want to change, select the ... icon, and then select Preferences.
2. Select the new data source in the drop down menu, and click Update data source. You should see that the component has been successfully bound to a new data source.
3. Click Return to Full Page.
   Note: This procedure only changes the data source for that single instance of the component.
