Phantom items are typically used in multilevel 'Bill of Materials' (BOM), where a single row of a phantom item serves the purpose of an entire sub-tree. These items do not exist in the inventory.

They are designed to be used in situations where several BOMs would have the same basic components. Instead of having to enter the same multiple rows into the BOM, 1 row with the phantom item can be used.

A practical application of a phantom item would be, for example, a basic cake mix for a bakery. This basic recipe plus additional items is used for a variety of different cakes.

The phantom item 'Basic Cake Mix' would be defined as follows:


Note that this item is purely a 'Sales Item' & the issue method is 'Backflush'.

A production type BOM for the phantom item could look like this:



Drawing this phantom item into another BOM:



Using this BOM in a production order:



The individual components of the phantom item appear in the production order.

Note that the phantom item/Bill of Material does not appear in the Production Order. Furthermore a Production Order cannot be created for a phantom Item/Bill of Material as it is not a stock item.
