Item Composition in Item Master

Hi:

Are there fields in JDE Item Master where we can enter a composition of an item? Example: We have Item# 12345 Wooden Box in Item Master. We need fields to enter what makes up this Wooden Box - wood, nails, epoxy, paint, etc.

If none, are there any businesses that have this kind of setup? How is this achieved though JDE in your business line?

Thanks!
