Updated report handling for simulations using database output
Resolved in Pega Version 8.5.3
When running a simulation with a database table as the output destination, the pxObjClass property was not populating with a value in the results. This caused sub-reports to not be populated with data. Investigation showed that issue happened when the simulation output destination database table was inferred as an external table due to not having an exposed column for pzinskey. To resolve this, the pxObjClass and pxCreateDateTime properties, which were added to simulation output destination tables for compatibility with Report browser, will not be added to those tables when they are created. Instead, to address compatibility issues of simulation output destination classes with Report browse in the Customer Decision Hub, the pyDefaultSummaryReport has been brought up into the Data-Decision-StrategyExecution-ResultOutput class from the @baseclass.

Logic updated for finding 'Last' in Interaction History
Resolved in Pega Version 8.5.3
The 'LastReponseDate' and 'LastInteractionId' in the Interaction History summary data set were null. Investigation showed that reusing the ESM component in the aggregation dataset caused any assumptions made during the optimization of ESM to not be true anymore. To resolve this, the logic of the Last aggregation has been modified to not rely on a Last event which might not be stored in-state (such as optimization), but rather to use the list of events which is always stored.

Implementation updated to ensure consistent compareDatesByDays results
Resolved in Pega Version 8.5.3
When using compareDatesByDays in a filter shape within a strategy, the results of the expression were different between the expression test and the strategy test run. This was traced to a difference in handling that became visible after upgrade; giving a negative number for the numberOfDays parameter worked differently in v7.4 than in v8.4. The SSA implementation of compareDatesByDays always worked with the absolute difference in days between dates, whereas the Java function in Pega used in expressions did not, and would compare negative differences as well. To restore the expected behavior, the SSA implementation has been adjusted to not work with absolute differences, and tests have been added to ensure equal results for the Java function in Pega and the SSA implementation.

Resolved strategy optimization exception
Resolved in Pega Version 8.5.3
After upgrade from v8.2 to v8.5, Customer Decision Hub strategy failures were seen in the data join used with a datapage/page list to fetch some results. Errors appeared in the logs and UI. The exception indicated that the Strategy Parser for the new execution engine (SSA) was not able to parse and inline the used expression. Normally this exception would be caught in subsequent processing and the component where the exception is used would fall back to legacy so as to not affect the runtime behavior, but this scenario triggered a corner case inside the parsing logic for Data Join and Exclusion shape which caused the exception and stopped the process. To work around this issue, the Data Join configuration can be split into two shapes: create a new Data Import shape to only import the Page list, e.g. 'Page.pxResults', then on the original Data Join component, instead of joining the 'Page.pxResults', join with the new Data Import shape. This issue has been resolved by catching the exception when compiling the Data Join component and properly falling back to the Data Join shape.

Unescaping characters implemented for expressions
Resolved in Pega Version 8.3.6, Resolved in Pega Version 8.4.4, Resolved in Pega Version 8.5.3, Resolved in Pega Version 8.6
An issue where expression builder statements were evaluated differently at runtime than at testing has been resolved. Pega Platform expressions with String literals(that is, sequences of characters enclosed in quotation marks) now unescape characters in strategy shapes such as Set Property or Filter.
