Defining phantoms
The Phantom check box in the Bill of Material (tibom1110m000) session determines whether LN treats an item as a phantom item. You can specify whether LN must always check if there is inventory available for a phantom by selecting the Use Phantom Inventory check box in the Bill of Material (tibom1110m000) session.
You can set default values for these check boxes in the Item - Production (tiipd0101m000) session.
