@GregStiles - I just faced this with someone else and realized it may not matter what the cost says on the Bill. If you do a cost roll-up it uses whatever is in Misc Item Maintenance, NOT the old cost on the bill, and if you do Production Entry, ditto. So it would only be an issue if someone looks at it on the screen or has a custom report, but if it's a custom report, you could add it in.
