Hi, 

I´m using Pega 7.3 and searching for circumstancing subject, I found this help article: https://community.pega.com/sites/default/files/help_v73/concepts/concepts2/conceptstimecircumstance.htm , which tells about contrasting time-qualified rules and historical processing. 

I became very interested about this historical processing feature and it seems to be exactly what I need, but the help file just gives an introduction about the subject. I couldn´t find any examples and how to implement such feature. 

Historical processing:

"With careful advanced design, this feature allows an application (for the current requestor) to operate according to rules as they were on a specific past date. Such processing is useful to reconstruct past behavior or apply past policies."

How to achieve this design?

Thanks in advance.
