7.4 Frequently Asked Questions
I need the accumulators to be reset upon period end. Which accumulator
should my application use? Resettable Accumulator or Archive
Accumulator?
You can use either one. The Archive Accumulators are reset every time a new
archive is created and you configure whether the archive should be created upon
period end and/or upon events.
There are some applications that may require the archives to be generated upon
period end and upon event while the accumulators should be reset only upon
period end. For these applications, you should consider the Resettable
Accumulator (configured to be reset upon period end only) because the Archive
Accumulators will also be reset when an event occurs.
