A PMML model contains undefined functions

Suggest edit
Updated on April 5, 2022

The PMML engine of Pega Platform does not recognize some of the functions that are part of the PMML model that you uploaded.

Cause

The PMML producers used proprietary expressions (custom functions or data transformations) with the PMML model that are not part of the model. The model contains only references to the functions and their parameters.

Solution

  1. Define undefined functions in Pega Platform or in a JAR file that you upload to Pega Platform.
