When we do a quotation for a customer we set it up as an opportunity. If we lose the order for some reason we then enter the reason. Over the past 3 years lots of different reasons have been entered and the list now has about 130 reasons on there.
I would like to clear this list and then define 10 new reasons that everyone uses from now on. However I believe that if I do that all old opportunities that had one of the old reasons selected will be cleared.
