Non-Stock Part - differences in Stock Status and IWR

We have a part called R&D that we use to run R&D jobs through the factory.
Until now, we have always issued the jobs to inventory when complete then write them off before the end of the month. At the end of November we had a large amount that was issued to inventory but not quantity adjusted out before the end of the month. It is creating a big difference between my stock status and IWR Report.
The part is Non-Stock, so how do I get the value out of that part to R&D expense now after the fact so my reports tie out?
