Published Release Notes

The Upload responses action is not supported for adaptive models with customized context

A default instance of the Adaptive Model rule contains five model identifiers (.pyIssue, .pyGroup, .pyName, .pyDirection, .pyChannel) that are used to partition adaptive models. If you add other identifiers in your Adaptive Model rule instance, you cannot upload responses to this instance with the Upload Responses wizard and the following error is displayed: The Flow Action post-processing activity pzUploadCSVFile failed: Cannot parse csv file.You can still train such adaptive models with data flows.

For more information, see Training adaptive models in bulk with data flows, Model context, and Uploading customer responses.

Changes to User Interface menu in Designer Studio

The User Interface menu in Designer Studio has changed. For example, menu options related to localization are now grouped under Application readiness.

For more information, see Designer Studio - Landing Pages.

Decision Analytics portal renamed to Analytics Center

The Decision Analytics portal is renamed to the Analytics Center portal. In this work area for predictive analytics and text analytics, the business scientist can control the full model life cycle by building predictive models, importing PMML models, building sentiment analysis and text classification models, creating and monitoring adaptive models, and updating any existing models.

For more information, Analytics Center portal.

New alert for distinct values query

The PEGA0093 alert identifies performance issues when a distinct values query from virtual reports or the getDistinctValuesForProperty API take longer than the threshold. For more information, see PEGA0093: Distinct values query took more than the threshold.

Use fast processing option does not work

The Use fast processing option on Connect REST and Service REST rule forms does not work unless you obtain the HFix-43000 hotfix from Global Customer Service.

Use the following data model guidelines when using fast processing:

• The JSON property names and the clipboard property names must match.
• The JSON tree structure and the clipboard tree structure must be similar.
• The scalar arrays in JSON must be mapped to the clipboard as page lists.
• Multi-dimensional arrays must be mapped into page lists of page lists with the same embedded property names.

​In addition, page groups, value groups, and Java objects are not supported by fast processing.

Behavior changes when reporting on descendant classes

Report Definitions that use the Report on descendant class instances option with the Include all descendant classes option apply only to the Applies to Class. Join classes are not included as they were in previous Pega^® Platform versions. The following example shows what happens for each possible scenario for Report on descendant class instances when the report is defined on ClassA with a class join with Work-.

• If Report on descendant class instances is disabled, the report runs against ClassA and the join happens with Work-. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
• If Report on descendant class instances is enabled, and Include single implementation class is selected, the report runs against ClassA and the join happens with the MySampleClass implementation class. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
• If Report on descendant class instances is enabled, and Include all descendant classes is selected, the report runs against ClassA and its descendants and the join happens with Work-. In previous Pega Platform versions, the join happened with the MySampleClass implementation class.

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.
