For example, in this above image, these four SKUs show a positive NTF (Need to Fulfill) quantity: LEVE-75, DIET-HYD38, ALUM-CHL-87, and PHEN-HYD-32. These are parts of the subassembly LIDO-HYD-41. And since LIDO-HYD-41 has enough units on the shelf and/or enough materials in stock to assemble more units, then those child items (i.e. LIDO-HYD-41 Bill of Material items) do not need to be ordered. Therefore, they are not included in the Dependent Order.
