Ruleset stack in pega

What is ruleset stack in pega

Ruleset list or stack is assembled by pega when the user logs into the application and ruleset stack is used during the rule resolution process. Rule resolution will be looking into the ruleset stack in a specific order so the order is important. Top Ruleset takes the highest precedence.

How pega will assemble the Ruleset stack ?

As we know each application is having a stack that is called application ruleset stack. Application Stack contains application specific rulesets and Organizational specific rulesets, combined we can call them as application ruleset stack. 

Lets see the below Application "OneHelp" which is built on OHFW framework application and Rulesets for OneHelp implementation application are :
  1. OneHelp,OneHelpInt - application ruleset for application configuration.
  2. PH,PHInt - organizational ruleset contains reusable organizational assets, such as data structures.

OHFW framework application ruleset stack is shown below:

Lets take the above application OneHelp is built on OHFW framework application which is built on UIKit and UIKit is built on PegaRULES application. Once the user logs into OneHelp application we will see how pega assemble the Ruleset stack for the operator. First, PegaRULES ruleset stack is added and on top of PegaRULES list UIKit ruleset stack, on top of UIKit OHFW ruleset stack and on top of OHFW list OneHelp application ruleset list, finally it will add if any personal ruleset (if we area allowed for rule check out) with the name of the Operator.
