Produmex - Multile Expiration Dates for a single batch

Produmex will sometimes create a second batch record for the same batch but with a different expiration date.   Our customers never intend this and would like to restrict this to have one single batch record with the same expiration date.   If you feel there is a valid reason that a company would have different expiration dates for the same batch, then we would recommend it as a configuration for each setup.   If not, we would recommend changing Produmex to not allow two expiration dates for the same batch.
