Hi Glenn
I think what MichaelG is asking that the quarterly and monthly splits should follow the accounting year in the system (rather then calendar year).
Logically, when one wants monthly/quarterly breakdown of the annual figure, they are looking for that particular annual figure to be divided into 4 or 12 periods. I reckon it will be quite confusing especially for non-accountant to not see this in the breakdown.
Please see my post from December 2016 here:
Many thanks
