This would increment the number on hand up to zero, but I am not sure of
any GAAP repercussions!!
It would also associate $0 cost of goods sold with the last purchase of the part. This may not be desirable, and might also make you pay additional taxes since your COGS would be underreported. I would probably not make a habit of correcting things this way. You want to have a good idea why this is occurring.
