Content (please ensure you mask any confidential information):

Finished Good (FG):FG001

Scenario overview:FG on-hand: 3,140Customer demand: 10,000Remaining FG to be manufactured: 6,860

Primary component (Bulk):COMP1On-hand: 1,000

Substitute components (all defined as substitutes on BOM):COMP2 – 1,000 on-handCOMP3 – 1,000 on-handCOMP3 – 1,000 on-hand
