To clarify the Poll once per activity period setting and how it works with contiguous blocks.
In the example will it run once during the three contiguous blocks or will in run once each hour?
I can think of reasons where both would be desirable, but for now just need to confirm how it will react.
Also would PPC 2020.1 and PPS 7.6.2.9999 both react the same?
In your example, the process would run twice:
The “Poll once per activity period” option refers to contiguous blocks. So that option tells the process to run only once, but for each set of contiguous blocks.
You could say that this setup runs the process once, twice… but that would just be even more confusing… 
That behavior is the same in both PPC and PPS.
This is what I always thought, but the entry in the PPs v7.6.2 help was unclear and being interpreted differently by the customer. They are moving to PPC 2020.1 thus the concern if it was different.
What they want in this case is to execute once during each block not contiguous blocks.
If I set the polling interval high for example every 31 minutes with 60 minute blocks… it would not run at the top of the hour, but only once correct?
They should untick the “poll once per activity period” option and set the Polling interval to 3600 seconds.
That way, if you have a single block selected, it will only run once because once the 3600 seconds have elapsed, the process will now have moved out of that block… If you have 3 contiguous blocks, it’s considered as “a single activity period”, during which the process will run every 3600 seconds (i.e. once per hour), which is what they want.
To be safe, they should actually set the polling interval to something like 3700, to make sure that the process never runs twice inside of a single hourly block.
