There are different ways to do this. The easiest that I have found is to do something like...
In data environment
1) Set the INITIALSELECTEDALIAS to the parent table (ORDER.DBF)
2) Set relationships by
a) dragging the ORDER.keyfield to the ORDERITEM.key_id_to_order_master,
b) dragging the ORDERITEM.keyfield to the DELIVERY.key_id_to_item
c) DO NOT set any other properties dealing with indexes (except the ORDER.DBF)

In the form
3) Create your ITEM grid and set the control source to the item table
4) Do the same for DELIVERY

When run, it should show properly
