Gordon,
Inventory Master Data indicated item is for Inventory, Sale and Purchase. But, the Production module has Bill of Material setup for this inventory item.  When CSR enters this item will show Parent and Component detail and AR Invoice needs to show Parent and each Component price break-down for customer to return any component. 
PO item needs to show Parent item (no need for each component items) only for vendor.  How to use one Inventory item but display differently in SO, AR and PO correctly is my question.
If the item called ABC for finished goods item and each price is $800 but ABC is the parent item that comes with C001 $100 1pc,  D001 $300 1pc and E001 $400 1pc.  We want to show ABC 1 pc $800 with detail C001 $100, D001 $300 and E001 $400. 
But, in PO we only want to show ABC 1 pc $550 (cost) to vendor without any component item.
