Continuing the discussion from Incorrect notes showing in account detail?:
I have noticed the same thing as mentioned before.
If you want to review activities for a nominal code and you tick the show all notes box, you will be given the first line of the description for the purchase logged (which might not be the item you are interested in, as that could be in the second line of the invoice in question).
However, more confusingly if you create a copy from a previous purchase and you change the description then save the new purchase, in the nominal code view you will be presented with the description of the purchase you made the copy from rather than seeing the correct description you entered.
Is this something that could be addressed at all? If you need to drum up sufficient interest beforehand, please change this to a feature request.
