More Information on process "Revalue Balances" Auto Increment Option

Hi Guys

We need to run the revalue balances process every day for our finance department to know the accurate GBP accounted balances of some accounts that have journals posted against them which are in a non-GBP currency.

I am interested in how the "Revalue Balances" Auto Increment Option works, the info on the checkbox says,

"Enables a procedure evaluated at runtime which calculates the next set of date parameter values for a recurring request"

But how does this procedure work?

Does it increment each of the dates chosen: "Accounting Date" and "Rate Date", what if the schedule goes over a month end, then what?
