Published Release Notes

Child case queries performance can be slow

Some customers have reported that performance is slow when they execute queries on child cases. This issue is often indicated by PEGA0005 (query time exceeded limit) alerts that can be correlated to these queries in the logs. To resolve the issue, add a database index to each of your work tables by using a multicolumn index on the pxCoverInsKey, pxObjClass, and pyStatusWork columns.

See Performance improvements for child case queries.

Updates to the Data Page rule form

You can use the enhanced Data Page rule form to specify the name of a source system in the System name field in the Data sources section. This field represents the name of the system that is associated with a data source. For example, if your data source is a REST connector that connects to an external weather service such as Google Weather API, you can enter Google Weather in the System name field for the data source. The system name is used to display the source systems for a data type on the External Data Entities landing page.

For more information, see Viewing external data entities.

Verify ML Readiness error: Upgrades from Pega 7.1.0 through 7.1.8 do not replace nonversioned rules

Upgrading from any Pega 7 Platform version between Pega 7.1 and Pega 7.1.8 to Pega 7.2 does not automatically replace nonversioned rules. If you revalidated and saved a Pega 7.1.x rule after the timestamp on the Pega 7.2 version of the rule, upgrading to Pega 7.2 does not overwrite the saved rule. You might see either of the following behaviors:

• The upgrade fails with the following error message:
  Verify ML Readiness
• The upgrade succeeds, but you might be unable to open changed rule forms.

If the upgrade fails, see the Pega 7 Platform Upgrade Guide to force the upgrade.

This known issue does not affect Pega 7.1.9. After the upgrade has finished, apply Hotfix 27288. For information about obtaining and applying hotfixes, see Hotfix Manager.

Unused agents run in background

The Update PegaRULES database table statistics agent and the Collect PegaRULES database blob size statistics agent have been added to support future development. These agents run in the background, but they do not do anything. You can, but do not need to, disable them from the Edit Agent Schedule landing page.

For more information, see Agent Schedule form - Completing the Schedule tab.

Unit testing support for more rule types

You can now create unit tests for the following additional rule types. You can also create assertions to validate activity status. The expanded rule types for unit testing enable developers to more thoroughly perform regression testing of their application, thereby improving application quality.

• Collection
• Declare expression
• Map value
• Report definition

For more information about unit testing rules, see Pega unit test cases.

Upgrade impact

With the four new rule types, unit test execution and unit test compliance metrics will change. Reports on automated unit testing of the customer application decrease due to the increased pool of supported rules.

What steps are required to update the application to be compatible with this change?

After a successful upgrade, create Pega unit test cases for the newly supported rules to see updated and accurate unit test metrics.

Use Page-Change-Class method to change a Page class

With the release of Pega Platform™ 8.3, using the Property-Set method to change the Page class shows a guardrail warning. Use the Page-Change-Class method to change the Page class instead.

For more information about the Page-Change-Class method, see Changing the class of a page and Page-Change-Class method.

Data and integration troubleshooting enhancements

Identify how data is loaded in user interface (UI) elements, discover the data sources used, and navigate to the relevant rules by using the new Live Data tool. Use the Live Data tool to quickly troubleshoot data and integrations by providing data page information or autopopulate properties from the UI without searching through the clipboard.

For more information, see Troubleshooting data in UI elements.

Retrieve a flat list of fields from Pega Digital Experience APIs

You can now use the flatListOfFields parameter to retrieve a list of the fields in a case or flow action. With this parameter, you avoid parsing all the layout information for the Pega Digital Experience API, making it easier for you to see only what you need to build your user interface.

The following Pega Digital Experience APIs support the flatListOfFields parameter:

• GET /casetypes/{ID}
• GET /assignments/{ID}/actions/{actionID}
• GET /cases/{ID}/actions/{actionID}

For more information, see Retrieve a flat list of fields from Pega APIs.

Drag-and-drop functionality for lists and tables

Lists and optimized tables now support the reorganization of their content by reordering items. By configuring repeating dynamic layouts and tables to support drag-and-drop modifications, you enable users to move items between lists and within lists and tables. This enhancement ensures that you can create a flexible and dynamic user interface that helps users display and manage data.

The drag-and-drop functionality can also include custom actions that automate the processes that run when users move items.

For more information, see Configuring drag-and-drop functionality for lists and Configuring drag-and-drop functionality for tables.

Customized application overview documents in App Studio

Keep stakeholders notified of the status of an application by customizing and generating an application overview document in App Studio. The overview may include information such as case types, roles, features in your application, and more. Select the chapters that you want to include in the overview, and then highlight the most relevant information by ordering the chapters. In addition to the application overview document, you can generate a detailed data model, either in Microsoft Word or Excel format.
