I think standard cost can only be changed at the component level. But I don't think you need to change it anyway. Although its on the prepost report, std cost is there for reference only. Actual postings are made at Average, FIFI or LIFO (whichever you use), so COGS is not being doubled, if that is your concern. If you just don't like seeing it on your report, I'll leave that in Lynn's hands.
