I was sure this was discussed prior (perhaps in one of the mailing lists)…
Currently, there are many cases where summing of lines selected (debit/credit) is disabled, and it turns out in our practice that it is mostly off rather than on, which is rather infuriating.
Therefore, we would like to know where (what module/file) to force things to always have the status line with a valid selected/total debit/credit as well as add balance.
