Structure Types
Product structure relationships normally have a blank structure code and are used by manufacturing planning and control and product costing.
An X is a local phantom code and adds this-level cost to the parent item, as well as the component’s cost. A global phantom adds only lower-level costs to the parent. See Effect of Phantoms.
Non-Costed Structure Types lists structure type codes that exclude the cost of a component from the product structure’s cost rollup.
