Procurement type for Phantom material is
D
Correct answer
Explanation
Phantom materials are virtual BOM structures used for planning purposes but don't exist as physical items, so they don't require a standard procurement type like E (internal production), F (external procurement), or X (phantom). The procurement type field is intentionally left blank or marked as 'Not maintained' for phantom assemblies since they're exploded into their components during MRP run rather than procured directly.
