Improvements for the PMML models
Valid from Pega Version 7.2
The Pega 7 Platform extends support for the PMML models to include PMML 4.2 features and validations. Additionally, the PMML files that contain custom functions can be imported into the Pega 7 Platform and used in strategies.
For more information, see Predictive Model rule form.
Improvements to the adaptive models management
Valid from Pega Version 7.2
There are several improvements for managing large sets of adaptive models that make model management faster and easier. In the Adaptive Models Management landing page, you can clear and delete models in bulk. In the Predictors tab of the Adaptive Model rule, you can add multiple predictors. In the Memory estimation tab of the Adaptive Model rule, you can estimate the memory that the Adaptive Decision Manager (ADM) system needs to accommodate the models that use the adaptive model configuration.

- Adaptive model form - Completing the Predictors tab
- Adaptive model form - Complating the Memory estimation tab
Improvements to the HBase data set, HFDS data set, and Hadoop host configuration
Valid from Pega Version 7.2
The Pega 7 Platform features maintenance improvements to the Hadoop host configuration, HBase data set, and Apache Hadoop File System (HDFS) data set. System architects can more easily make HDFS and HBase storage available to business scientists for exploratory analysis and predictive model building.
For more information, see Big data functionality enhancements.
Data Flow rule enhancements
Valid from Pega Version 7.2
The enhancements to the Data Flow rule facilitate decision execution in real time, batch, and Pega 7 Platform applications. The DataFlow-Execute method in activities can be used to execute and monitor batch runs and real time data flows. In addition, you can configure pre- and post-activities that are executed before and after data flow execution.
For more information, see the following Pega 7 Platform help topics:
Strategy canvas enhancements
Valid from Pega Version 7.2
The Strategy canvas in Decision Management has been enhanced to let you to create, edit, and display your strategy more easily. You can keep your strategy in order using the Smart Mini Map, improved selection capability, and the new Align and Distribute options. Additionally, you can perform the most common operations using keyboard shortcuts and accelerators.
For more information, see Strategy rule enhancements.
Naming pattern changed for file data sets
Valid from Pega Version 8.6.3
File data sets are used to import from and export data to a file repository. In case of data export, prior to version 8.6.3, the first file exported had the same file name that was provided by the user in the data set, and any subsequent file exported to the repository had a unique identifier appended to it. Starting in Pega Platform version 8.6.3, each file has a unique identifier, automatically generated based on the data flow node, thread ID, and timestamp.
Upgrade impact
If your process to consume output files expects files with a specific name, it may not be able to process the resulting files correctly.
What steps are required to update the application to be compatible with this change?
If you have configured the process before updating to Pega Platform version 8.6.3, but the exported files are no longer recognized by downstream processing logic after the upgrade, ensure that the downstream tool is configured to recognize the files by a pattern rather than the full name. For example, when referring to files exported to the repository, use the * character to indicate a pattern instead of using the full file name. For example, use Export*.csv to refer to the files.
