I created a Dummy Company X, and Dummy Company Y, and exported it to Excel so I could set the format to import many other customers. There's a "parent_id/id" field exported, which I thought referred to the customer's parent company. However when editing the form I can't find any spot to assign customer X as a child of customer Y.
Have I misunderstood parent_id? Where can I make this association? Where will this association show up after it is made?
