Quantities-on-hand of local phantoms do not impact the Simulated Picklist Item Check (13.8.17) or the Simulated Batch Ingredient Check (15.7.17). Use-up logic is typically not applied to local phantoms. This is one reason to define them as local, rather than global. Quantities-on-hand of global phantoms still decrement quantity requirements when you select use-up logic by setting the Use up PH field to Yes on these two inquiries.
