cannot display the chart as the PMML is not generated from R

Hi all

I am working with SAP Predictive Analysis 1.15.
when i use R-CNR tree the data grid and confusion matrix is generated successfully but when i go for decision tree representation it throws an error

"cannot display the chart as the PMML is not generated from R

Details:

Either input column names contain space or PMML package is missing."

but i have installed pmml package. and there are no space in my source data.

I have attached the data grip which i get as result and the error which is thrown when i go for tree structure

the feature columns i mentioned are:

the target column is outcome.
