Resolved Intermittent Access Group Issue for GetBundleEventDecisionDetails
Resolved in Pega Version 8.5.2
When using a REST service that calls the GetBundleEventDecisionDetails activity and dataflow to send the treatment in multiple channels, intermittent access issue related errors appeared while running the activity in logs for multiple customers. This was traced to a missed use case for authentication, and has been resolved.

Support added for expression in strategy scorecards
Resolved in Pega Version 8.5.2
When invoking REST against a dataflow that had a strategy containing a scorecard that used an expression and the "Include model explanations option" was enabled in the Strategy configuration, the system failed with the error "PropertyValueInvalid .pxMaxScore Cannot cast the value (unknown) to double". This was traced to the Scorecard explanations failing during serialization when an expression was used, and has been corrected.

VBD performance improvements
Resolved in Pega Version 8.5.2
Performance issues were seen when running a decision funnel simulation. As part of the simulation, a VBD collection was created on the fly to store the metrics and linked to the simulation. Before each insert, which happened in batches of 500 records, there was a check if such collection exists. This check was required in earlier versions as the process relied on the VBD service being running, and the run would fail otherwise. Recently, VBD handling became more resilient and was updated to allow inserts even if the VBD server is down. If the VBD service is stopped before the simulation is completed, the simulation will continue writing records. When the VBD service starts again, it reads the backlog, and the simulation displays the final results. To adapt to this resiliency and improve performance, the system has been updated so that the VBD collection is not created and checked before the insert call, but only when the simulation is run or scheduled.

Strategy Simulation Runs made more resilient
Resolved in Pega Version 8.5.2
Intermittently, a decision funnel simulation would fail with particular strategy logic or a particular StrategyTracker would not contain the results for all components so the system would not be able to calculate input SRs. Handling has now been added to make the simulations more resilient so they will not fail with a null pointer error due to incomplete strategy inputs.

Unneeded AUC error percentage calculation removed for better system performance
Resolved in Pega Version 8.5.2
When generating snapshots of the ADM models, an inefficiency in the metric calculation for the AUC error percentage caused an excessive amount of memory to be allocated which could cause slowdown or require a system reboot. This has been resolved by removing the problematic AUC error percentage calculation as it is not used in the UI.

Enhancements added for very heavy use of strategy decision logic
Resolved in Pega Version 8.5.2
Recent updates were made to improve memory performance for scenarios where a single request primary page had tens of thousands of pages under an embedded pagelist property and the decision logic involved a strategy running on all the pages in that page list. To further improve performance, the array iterator has been modified and a DSS has been added that makes the threshold (50) in SSAExecutionContextIteratorFactory tunable.

Logic optimization disabled in offers
Resolved in Pega Version 8.5.2
Offers that should not be eligible to customers were passing through even though the offer was narrowed down to using “OR” conditions in the Engagement policies. This was traced to the logic optimization ignoring precedence, and has been resolved by disabling the optimization.

Jsoniter parser upgraded
Resolved in Pega Version 8.5.2
After upgrade, the pxTextinput property Prompt List was being converted into decimal upon clicking finish assignment. This was traced to the jsoniter parser, and has been resolved by upgrading the parser in the jsoniter library.

Corrected mobile data transform format handling
Resolved in Pega Version 8.5.2
An intermittent issue was seen in the mobile app where data was not propagated properly because a Data Transform failed. The error "Failed to run data transform fs_work_task_plannedtask_settaskdetailsfromparent TypeError: sourceProperty.getValue is not a function" was generated. This was traced to a difference in the generated data transform format where a success scenario considered “Problem” as a page, whereas a failure case considered the “Problem” as a property and the getValue() operation failed. This has been resolved.

Handling added for overriding questions rules
Resolved in Pega Version 8.5.2
After overriding questions rules and then upgrading/validating Question Groups, questions were not shown. It was necessary to manually edit, save, and refresh for the questions to appear, affecting mainly Rule-PegaQ-QuestionGroup rules. This was traced to missing handling for this usecase. The commit was added in Revalidate and Save, which was committing different data because the upgraded data was not copied back to step page being used. Due to this, the commit in BulkValidateSave was overriding the changes done in the pzUpgradeSurveyInstance activity, and the survey upgrade was failing. To support this use, Page-Copy has been added to pzUpgradeSurveyInstance after the pzSaveSurveyInstance call step to copy the updated data to the step page which will later be committed by BulkValidateSave during revalidate and save.
