When entering a bill if you put the same invoice numer in the reference field it will alert you that another bill already has this number, why doesn't it do that with Credits? I have a vendor that credits dwindle in and then they send copies again with the statement, I'm dealing with a lot and many times because QuickBooks does not have the alert for a duplicate number in the reference field for credits I end up with duplicates and I take them twice. Doing a search for each one beffore inputting it is a hassle. I was hoping in 2009 this would have been fixed but it hasn't. It makes no sense.
