Hi, I read through the links you sent, and it doesn't seem to be the same issue. It looks like my inventory is pulling correctly when we do a regular "Build Assembly," but that may be because the issue is only when the item is actually sold - which would be why the Build Assembly is showing a credit where there shouldn't be one on my Profit & Loss Transaction Detail by Account. 

Would there be any reason that a Build Assembly would ever show a credit if it is pulling correctly from inventory? Nothing about the Inventory Assembly Items used to make the "Build Assembly" are negative.
