Reports have access to historical data… do formulas?
It would be very useful to track the change in a numerical value over a particular timescale.
Some of the cumulative flow charts I produce (historical data) show this change in numerical value on mouseover (green/red numbers with up or down arrow). Can I calculate these values and get them into a table?
I’m afraid formula fields can only access current data, sorry.
It is possible to add extra fields and define automations (triggered on a schedule or on updates) to log values just for this purpose, but this requires a bit of work I’m afraid.
