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.

Exported Excel from Decision Table wraps correctly
Resolved in Pega Version 8.5.2
After upgrade, entries were displayed in a single line on exporting a decision table to Excel despite WrapText cell formatting being set. This was traced to the WrapText cell formatting set under the UpdateGridCells() function being overridden inside an addDataFormat() function callas part of DecisionTableWorkBookConverter.java. This has been resolved by adding the new function "setWorkAreaCellStyles" and calling it after generateWorkbook() function call of super class (AbstractWorkBookConverter.java).

JAWS reads the name of the field/instructions
Resolved in Pega Version 8.5.2
JAWS was not reading the name of the field/instructions in a work group. This has been corrected.

Mask hidden as expected in small window/tablet view with Dragon
Resolved in Pega Version 8.5.2
When using Dragon in a small window/tablet view, the mask was not getting removed as expected. Performing a mouse click on the tab was successful for hiding it. To resolve this, Data-portal!pzProfileMenu has been modified to run the script removeScreenLayoutMask after clicking Profile, Preferences, Operator, Access Group, and My Favorites > Edit .
