Lot traceability on consumable products

Hi,
We have consumable items (such as flux, alcohol) which we need to
record the lot number we use on each job. We were going to put these in the
bill of material and put a quantity of .0001 and then issue once the job is
complete. I thought there may be an easier way to do this. We are not
trying to get the cost of the product to the jobs, and we are not trying to
control inventory (we will just use a minimum and control that way). Does
anyone else have circumstances like this? How are you handling it?
Thanks,
