How to enter raw material supplies in T2 (Expense and/or Inventory)

Hi Community!  I have a question regarding tracking of raw materials as an expense vs inventory within a corporate tax return. 

 

Do I track the raw materials I purchased (to be made into a finished good) as an Expense in my T2 (Selling Expense, Supplies, etc) as well as including its cost as inventory (finished and raw) or is it one or the other?

 

Where my confusion is (I think), is by tracking the raew material as an expense and as part of a finished good in inventory (or as a raw material) it feels like its double-dipping (recording the same items more than once).

 

Not sure if my ramblings make any sense at all but hoping someone can assist.
