What makes the Property-Validate and Page-Validate methods different from one another?

Every property on a page is validated using the page-validate method. This function will validate all the properties recursively if a page has embedded pages. This approach takes longer and consumes more system resources. To validate specific properties, use the Obj-Validate method in conjunction with a Rule-Obj-Validate rule.

A property’s value can be restricted by applying the property-validate method. Use the Edit validate rule when combined with the Property-Validate method to implement constraints. You can validate many properties at once with the property-validate function.

Where will assignments be saved in the Pega rules database?

pc_assign_worklist stores work list-related assignments.

pc_assign_workbasket stores workbasket-related assignments.

The following is the distinction between the Page and Page List properties:

  • A page property refers to a certain class and is used to access that class’s properties.
  • Page List Property also refers to a specific class, but it is a collection of individual pages of the same class that may be retrieved via numeric indexes.

What do you mean by “work object” in Pega? 

The fundamental unit of work accomplished in an application is the work object. A flow operates on the original collection of data. A work object is generated, updated, and eventually closed (resolved) while using an application.

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

Check out the frequently asked Blue Prism interview questions and answers.

In Pega, how do you create an object?

The following are the steps we must take to create a work object in Pega:

  1. To begin, insert a button, such as a section or a header.
  2. Click the action tab after expanding the cell property within the button.
  3. Set an action for the button.
  4. Add the focus class and flow name to the button.
  5. “Param.prevRecordkey” returns the current work object ID.
  6. Use the “Obj-Open-By-Handle” command to open the case.
  7. Page-Copy is used to copy data from pagers.

What distinguishes declare pages from regular pages?

The distinctions between regular pages and declare pages:

Declare Pages

  • Declarative rules are used in the creation of declare pages.
  • For a declare page to be created, the declare keyword needs to be given.
  • Declare pages to be read-only; they cannot be directly edited or removed.

Regular Pages: 

  • The page-new technique is used to build regular pages, also known as user pages.
  • It is simple to edit or remove these pages immediately.
  • The moment you log out of the system, these pages are instantly removed.

What types of layouts are possible in Pega?

These are the several layout options that Pega offers:

Screen Layout: Usually used to create gateways for an application, screen layouts are exclusively utilized inside of a harness.

Dynamic Layout: Using a DIV-based layout, the dynamic layout allows for multiple content displays.

Column Layout: We can display important content, like a work item, with auxiliary information, such as an attachment, by using a column layout.

Grid Layout: Another name for the grid layout is table layout. It facilitates data retrieval and comparison for users. Tables serve as a versatile foundation in this design that enables users to process large amounts of data in your apps. “Tables” in price comparison software are an example of a grid structure and can help users find the best bargain more quickly.

Tree Grid Layout: The properties of integrated pages can be viewed, navigated, and accessed using the tree layout. It makes it easier for users to quickly expand and contract the tree’s branches to find entries that are currently of interest.

You can add content, such as properties, controls, and additional sections, to a section in dynamic and column layouts. The width, alignment, positioning, and arrangement of elements in a layout are all determined by the skin’s format.

What are the primary benefits and drawbacks of declaring pages in Pega?

Benefits of Pega’s Declare Pages:

Declaring pages has the primary benefit of avoiding numerous database hits. Assuming that a node has several requestors, load activity will start at the initial user’s login, creating a declaration page before loading the data onto it. The requestors on that node view and use this declaration page and its contents.
