Heads up for those of you who work with JobOps: there is a problem in 4.40 where the unit cost gets screwed up during the invoice update process for credit memos generated from the RMA module, at least for lot/serial items (the client who discovered the problem has everything with those valuations). After much back and forth and sending the client's data to JobOps they have acknowledged the defect, but no fix yet. The controller at this client checks her inventory and WIP values vs the GL accounts at the end of each day, so someone who is not paying such close attention may not even know they have the problem.
