Must say, it was a bit unexpected for me to get to the point at once in TeamDesk blog how one should calculate a running total.
TeamDesk guys offer to apply the same method as by finding duplicates.
Lets try it out.
So I created the app in TeamDesk for my experiments:
According to the example I created many-to-many relation of mine with match condition which filters needed records and adds required column for sum calculation of these records:
This is calculated running total in TeamDesk:
The best thing is that in TeamDesk running total is calculated for each record and is added according to new record as a new field, what allows using this value in other reports, like these:
I am satisfied with the results. Running total calculation through TeamDesk is really easy. The Setup is maybe not that simple as in QuickBase, but a way better than in Coghead. I would like to make a special mention of the opportunity to use calculated running total in other reports.
