Frequently Asked Pega Interview Questions

The page-validate method is used to validate all the properties present on a page. If a page has embedded pages, this method works recursively to validate all the properties. This method consumes a lot of system resources and takes more time. If you want to validate specific properties use the Obj-Validate method with a Rule-Obj-Validate rule. A property-validate method is used to impose restrictions on property value. Use Edit validate rule along with Property-Validate method to impose restrictions. You can validate multiple properties using the Property-Validate method.

What is the difference between Edit validate and Edit Input rules?

Edit Validate: Use the edit validate rule to validate the property value using java code. Edit validate rules can be used property-validate, Rule-Obj-Validate, and Property rules.

Edit Input: Edit input rules convert user-entered data into the required format. For example, if the user enters the date MM/DD/YYYY format, the edit input rule covers this date into DD-MMM-YYYY (required format). Again we need to write java code for this transformation.

Q. How to create a work object in Pega?

Ans: The different types of standard classes available are.

Base class: It is the ultimate base class, and Its Child Classes are work-, Data-, Rule-, Assign-, History-, etc. Pega always supports two types of classes which are abstract classes and concrete classes.

Abstract Classes: These classes end with ‘-‘ and abstract classes cannot create any work object instances.

Concrete Classes: It does not end with ‘-’, and abstract classes will create work object instances.

Ans:

Page property refers to a particular class and is used to access the property of that class.

Page List Property also refers to a particular class, but it’s a collection of individual pages of the same class which can be accessed through numeric indexes.

Ans:

A work object is the primary unit of work completion in an application and the primary collection of data that a flow operates on.

When an application is used, work objects are created, updated, and eventually closed (resolved).

Every work object has a unique ID (property pyID), an urgency value, and a status (property pyStatusWork).

Ans: The following are the steps implemented in creating a work object in Pega.

Add a button such as a section or a header.

Expand the cell property within the button and click on the action tab.

To the button, add an action set.

Add focus class as well as flow name to the button.

Catch the present work object ID with “Param.prevRecordkey”.

Using “Obj-Open-By-Handle”, open the case.

Using Page-Copy, copy the data from pagers.

Ans: Direct Capture Object is an apple dev tool that includes.

Application profiler wizard.

Appl Accelerator.

Appl Doc Wizard.

Ans: The steps to trace SLA in Pega are:

Terminate the agent.

Delay it.

Initiate the agent.

Delay it again.

In the requestors, select the delayed requestor and click on the tracer.

Send this case to a particular assignment containing the SLA within 60 seconds.

Ans: The following are the different layouts types available.

Column layout.

Grid layout.

Portal layout.

Dynamic layout

Ans: A RuleSet in Pega is a collection of rules of business that defines an instance. The ruleset is an essential subset of PegaRULES that is necessary to reference instances in the database.

Ans: Yes, commit is used to save the data permanent in the DB.

Ans:

Access groups make a set of RuleSet versions available to requestors.

Use an access role name to convey permissions (capabilities) to a user or a group of users. Access roles can be referenced

in requestor instances, Operator ID instances, in access group instances, in activities, and in queries.

Ans:

Cover is work object that is parent to one or more related work objects.

One work party is present in the cover work object and also present in the covered work objects associated with the covers.

Folder is work object in concrete class that inherits from the work-Folder-class.

A folder object holds a collection of one or more other work objects providing access for reporting.

Ans: An access group in Pega is an example of a Data-Admin-Operator-Access Group class that creates a set of RuleSet for the requestors. The developer defines access groups and assigns them to different users.

Access Group controls the security based on the job functions. It is the instance of Data-Admin-Operator-AccessGroup. Various aspects that can be controlled through an access group are

Default and available types of works (also called as work pools).

Primary rulesets (Access Control to rulesets).

Assigned roles.

Portal layout.

Default ruleset for making changes (Default ruleset whenever the user creates/ saves as the rule).

Ans:

Browser requestor – Starts with letter ‘H’

Application requestor – Starts with the letter ‘A

Batch requestor – Starts with letter ‘B’

Portal requestor – Starts with the letter ‘P’.

Ans: It is the instance of the Rule-Obj-Flow Action rule type. It is the one category in UI specifying the choices to the user performing assigned work objects.

Local FA: If action is finished, the work object returns to the same level.

Connector FA: If action is finished, the work object moves to the next level.

Ans: The system adds entries it finds from the following sources in the order listed. The system adds entries it finds from these sources in the top of the list.

Requestor: (Data-Admin-Requestor class) — Usually this adds the RuleSets named Pega-RULES, and Pega-IntSvcs and a version or version prefix for these.

Division – As referenced in the Operator-ID instance.

Organization – As referenced in the Operator-ID instance.

Access Group: As referenced in the Operator-ID instance.

Ruleset Versions – Prerequisite RuleSets and Versions to those already compiled.

Operator ID: If this user has the ability to check out rules, the personal RuleSet (named the same as the Operator ID key) is added last. It is also called a private ruleset.

Ans: The declarative rule is an instance of a class derived from Rule-Declared.

They allow for automatic processing of Property values.

No need to be called explicitly.

No need to run in a sequential fashion.

The system manages re-evaluation when it detects a change.

The declarative rules in Pega are.

Rule-Declare-Expressions.

Rule-Declare-Index.

Rule-Declare-Trigger.

Rule-Declare-OnChange.

Rule-Declare-Constraints.

Ans:

Page-Validate:

This method is used to validate all the properties present on a page. If a page contains embedded pages, this method works recursively to validate all the properties. This method consumes a lot of system resources and takes more time. If you want to validate specific properties use Obj-Validate method with Rule-Obj-Validate rule.

Property-Validate:

This method is used to impose restrictions on property value. Use the Edit validate rule along with Property-Validate method to impose restrictions. You can validate multiple properties using the Property-Validate method.

Ans: Case management in Pega enables a user to adapt to the unpredictable, event-driven or automatic changes in a case and its processes. It pools real-time adaptation with unique solutions for every case to suit ad-hoc additions. It also saves the case as a template for the future application.

Ans: The advantages of Pega case management are.

Improve the processes of case management with holistic support.

Increase the efficacy of case-flow for automatic and dynamic response.

Ensures consistency and removes errors with context-based and real-time management.

Lessen time, costs and effort needed to implement case management.

Ans:

Decision trees are instances of the Rule-Declare-DecisionTree rule type.

Decision tree accepts one input property value but can evaluate numerous properties. It is best used for complex if/then/else statements.

It can capture and present business logic in the form of one or more if/then/else conditions.

It can be referred from three other rules from the decision shape of flow rule.

In activity, we can evaluate the DecisionTree using Property-Map-DecisionTree.

Decision trees can be referring to Rule-Declare-Expression.

Ans:

Decision Table:

The logic implemented in the decision table is if, else if condition.

In the decision table, if the first condition is true, it will not check the remaining conditions/if the first condition is false, then only it will check the next condition.

For simple logic, we can go to the decision table.

Decision Tree:

The logic implemented in Decision Tree is if, if condition.

In a decision tree, if the first condition is true or false, it will check all conditions and it will return results.

For simple logic, we can go for a decision tree.

Ans: A map value rule is a rule that converts one or two input values, such as latitude and longitude numbers, into a calculated result value, such as a city name. The rule uses ranges for the input value or values and a matrix to look up the result. Map value rules are instances of the Rule-Obj-MapValue rule type. This rule type is part of the decision category.

Ans: It is an Interface that shows up for the client either developer or an end User and entry can be arranged in Access Group.

Example: Developer entry, chief gateway, client entryway, administrator entrance.

Ans: Locking is acquiring control over a work object before proceeding to perform any action on it and to ensure only a single user to perform actions on a work object at a time. There are two types of locking as stated below.

Default Locking: Only one user can work on a work object at a time.

Optimistic Locking: This is an enhanced feature introduced in Pega 7, where multiple operators work on the same object at a time.

Ans:

Declare Trigger runs an activity when instances of a specific class are created, updated, or deleted in the DataBase.

Declare Trigger is always Forward Chaining.

Ans: Forward Chaining provides the automatic calculation of the property by executing the declarative rule when any one of the input property values is changed.

Example: If the Area property depends on the length and width property, then Forward Chaining causes the area property to be recalculated every time either length or width values change.

Ans: BackWard chaining provides the automatic calculation of the property by executing the declarative rule when the value is needed for the property, rather than when an input changes.

Example: If the area property depends on length and width property, the backward chaining causes the area property to be recalculated each time the area property is required.
