We faced a similar issue and found out that SAS Viya only supports PMML v4.2, not PMML v4.4. The following community link discussed how to create a properly formatted PMML 4.2 for R, though you might find that PMML 4.2 might not support the model you're trying to deploy. https://communities.sas.com/t5/SAS-Nordic-Users-Group/Juletip-14-Importing-R-model-to-SAS-Viya-with-PMML/td-p/521412 If this doesn't work, your options would be to recreate your model using SAS code and deploy that publish your R package to a supported container service more details on the PMML implementation are in the SAS Model Manager documentation https://documentation.sas.com/doc/en/mdlmgrug/15.3/p0t1l5scv87yoqn1m13rzx6yy45g.htm Best of luck!
