If data in the List is by default obtained from a Form however, it can be obtained from an external source. One of the prerequisites of the external connection is that a Form must be created so that a mapping can be created between the external source and the QMS. Once a form has been created, a connection setting must be created to connect to the external database and mapped with the fields on the Form,  open or create a new List Setting, navigate to the Basic Details section and set the Form from above and set Is External? field as checked. Set the newly visible Database Connection with the name of the Connection where the data is obtained and mapped with the form of the List.
