Hi Jen_d, 

Thank you for your reply, but I don't think we are on the same page with this. I don't need to update the asset account for my assemblies since they are correctly going to the right account (Finished Goods). My problem is with the depletion of my packaging materials. 

1. I changed the asset account for all packaging items to my new account Packaging Materials from the old Raw Materials

2. All of the item receipts related to these items are correctly posting a debit to my new Packaging Materials account

3. All of my historical build assemblies that use this inventory item have a credit to the old raw materials account, I assumed this would change to the new asset account (Packaging Materials)

4. Now I'm left with all receipts for these items in one balance sheet account and all credits or depletion of these items is posted to another balance sheet account. 

5. I need the historical builds to credit the new Packaging Materials BS account and not the old Raw Materials account

Basically when I created the new account and assigned all of my packaging items to it, QB moved the receipts to that account but not the builds. 

Hopefully this clarifies my original question!

Thanks!
