Published Release Notes

Enhanced data modeling

You can now create data types quickly in Pega Express. Use the enhanced Data Designer user interface to define the data model for your data types. More field types have been added, and they are categorized as simple, fancy, and complex to meet your data modeling needs.

For more information, see Data Designer enhancements.

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.

Case-insensitive filtering in reports

Filtering in reports is now case-insensitive, improving the reporting and searching experience. You can turn off case-insensitive filtering, for example, by using an activity. You might want to do this if your index is too big or if the length of time it takes for indexing impacts performance.

For more information on report filtering, see Editing filter conditions.

Add subspaces within spaces

You can now create subspaces within spaces. By adding a subspace, you can collaborate on a subtopic that is related to the topic of the parent space. For example, you can create an Annual Day subspace within the Events space.

For more information, see Creating a subspace.

PATCH support for REST integrations

REST connectors and REST services now include support for integrating with REST APIs that require using the PATCH method. REST integrations that support the PATCH method allow you to make partial updates to individual resources while retaining data that does not require an update. With PATCH support, you no longer need to write complex custom code to integrate with services that require using the PATCH method.

For more information about REST integrations, see Connect REST form - Completing the Methods tab.

Configure REST connectors for standard-compliant endpoints

REST connectors now support all standards-compliant endpoint URLs, regardless of how those URLs use query parameters.

This URL support allows you to do the following actions:

• Include repeated query string parameters in a URL.
• Omit a query string parameter if the value of the parameter is empty when you send a request.
• Apply appropriate encoding for different URL components.

For more information about REST connectors, see Connect REST form.

Support for sourcing case and Pulse attachments from repositories

You can now source case and Pulse attachments from repositories, which provides a complete solution for attachment management. In addition, unlike other external sourcing solutions, repositories do not require OAuth 2.0 authentication, so that you can connect to repositories that use non-interactive authentication.

For more information, see Configuring external sourcing options for attachments.
