Mfg BOM is excellent for tracking serials and lots. We have medical companies using it specifically for this and it more than satisfies the traceabilty requirements. The Mfg also has routings which allow for tracking of labor. I would not encourage the use of both as it gets confusing for users and also more difficult for reporting.
