Using the skills we've gained from defaulting values on the fields, we will now try defaulting the Description field from the Item table when the user enters a value in the Item No. field.
For the coding method, or the method that's more consistent with out of the box Dynamics NAV, the table we want to use is the Item table. The field we want is the Description field from the Item table.
A reason why the FlowFields method would not work in the Complaint Line table is that if we set the field to be a FlowField, we will need to set the Description field as non-editable. This will not work because the user should be able to type in their own descriptions as they are entering data in the complaint lines.
