In Pega Platform™ applications, a data page retrieves data from a specified data source and caches that data in memory. A data page manages the integration to the data source, separating business processes from any integration details.
How do I use data pages in Pega Platform?
You can use data pages to integrate APIs that contain complex input with Pega Platform. Data pages accept objects with scalar inputs, such as a Customer object with inputs for Name, Address, and City. Cause a data page to refresh the next time it is accessed by removing or forcibly expiring the data page.
What is data separation in Pega?
This separation allows application developers to use sourced data in an application without knowing the data source and connection details. Unlike most pages used in Pega Platform, applications only attempt to populate the contents of a data page when the page is accessed, rather than through an explicit action.
What is a data page?
Due to the on-demand nature of data page content, data pages are considered a type of declarative rule. Pega Platform automatically prepends the characters D_ to the name of a data page to differentiate the page from other pages in memory.
How do I check which ruleset versions are available in Pega?
Pega will open access group - application and see the ruleset stack to make sure ruleset versions are there. When a data page is loaded on the Requestor scope (level), all the threads opened by this requestor can use data from the data page.
What is a data page?
A DataPage is a web interface that allows you to view, edit, manage and password-protect data stored in your online database. DataPages allow you to easily interact with your data on a web page, while securely hosting your database in the cloud.

Provide values for the required parameters, and optionally for the non-required parameters.
Why do we use data pages?
In Pega Platform™ applications, a data page retrieves data from a specified data source and caches that data in memory. A data page manages the integration to the data source, separating business processes from any integration details.
What is a harness in PEGA?
A harness organizes the structure of a portion of the user display. In Pega, you use a harness to organize either a work form or a portal. Pega applications commonly use four standard harnesses to organize the content of user forms.
What is case type in PEGA?
A case type is an abstract model of a business transaction. Case types model repeatable business transactions. A case is a specific transaction instance. To model the online order transaction in Pega Platform, you define an online order case type that advances from submission to processing and then delivery.

What is synchronous and asynchronous in PEGA?
If execution mode is configured as synchronous (immediate), then the request is handled and processed in the single requester context immediately. If execution mode is configured as asynchronous (queue for execution), the request is handed out to the queue and processed later.
What is the difference between node and thread in PEGA?
Node – any requestor executing on the current node can access the pages. Thread – the page is created in a single requestor thread, and can be accessed as often as needed by processing in that thread.
How do you call a data page in an activity?
If you want to load a datapage asynchronously use Load-Datapage method or Call-Async-Activity method in an activity. Or else you can load a Datapage from a datatransform by simply referring the datapage name in a step in datatransform.

Scope of data pages
The scope of a data page defines the thread that can access the data page. You can select the scope on the Definition tab of the data page.
Types of data pages
Read-only – This is a read-only page available to only one thread, a requestor, or multiple requestors (on one node) in your application. Read-only data pages can be modified only during page load and post-activity processing. These data pages are displayed in the data page list on the clipboard.
Refresh strategy for data pages
The refresh strategy for a data page determines the time period for which the data page is valid. You can define the refresh strategy on the Load Management tab of the data page.
Access restriction while retrieving data from data pages
You can assign access control policies to classes which restrict retrieving data from those classes. If a node-scope data page is defined on such a class, a severe guardrail warning is shown. Also, if a node-scope data page is populated and the data page object class has access control policies assigned to it, a severe security alert is shown.
What is a data page?
A data page loads data to the clipboard for the system to use. The system can access data from the data page on demand. On the first reference of a data page (in data transform, activity, etc), the Data page will be created in the clipboard and loads the data to use.
How many threads does Pega create?
Both the work objects are opened by the Same requestor (CSR) and pega creates two threads for two work objects (CS-1 and CS-2). If we go to the clipboard and see the data page, data might be different from CS-1 to CS-2, because pega populates data specific to the work object (thread).
What happens when Requestor2 is using the same data page on the same node?
If Requestor2 is using the same data page on the same node, data is accessible to the threads (work objects) which are opened by Requetor2.
How many modes can a data page have?
We can create a data page in three modes.
Which data page can be used for two work objects?
Two work objects can use the D_ServiceRequestList data page which is in the Requestor level.
Who can access data from this node level data page?
All the requestors who are currently in that particular Node can access the data from this Node level data page.
Can a data page have two types?
We can create a data page with two types either a single page (holds a single object/page) or List (Page List - holds multiple objects/results/pages) type.
Data page reference methods
You can reference data pages with or without parameters, or by using keys.
Direct data page reference
Referencing data pages directly from rules allows the system to retrieve accurate data from the appropriate data source on demand. You can reference data pages with parameters when you do not have to maintain hierarchical relationships or case context.
Data page reference by using auto-populated properties
Auto-populated properties are page or page list properties that automatically obtain data directly from specified data pages. As a best practice, use these properties to access and source data from multiple hierarchically-related data pages more easily.

Results
The system uses rule resolution to locate the correct instance of the data page.
Checking the method status
This method updates the pxMethodStatus property only if it fails. See How to test method results using a transition .
