Ensemble of Random Forest and Neural network node in Enterprise Miner

I am trying an ensemble of random forest and neural network in Enterprise Miner, but its not working. Because random Forest scoring requires inputting some macro variable such as input and output dataset, the ensemble node is failing with error:

 

NOTE: Line generated by the macro variable "HPFST_SCORE_INPUT".
1 &em_score_output
-
22
76
WARNING: Apparent symbolic reference EM_SCORE_OUTPUT not resolved.

ERROR 22-322: Expecting a name.

ERROR 76-322: Syntax error, statement will be ignored.

 

How can I overcome this problem?

The HP Forest node cannot be used with the Ensemble node since it does not produce DATA step score code.

 

You can see this post though for some flows that can do some alternative ensemble methods, as well as the simple ones that are available in the Ensemble node but that will work with the HP Forest node: https://communities.sas.com/t5/SAS-Communities-Library/Quick-guide-to-implementing-advanced-ensemble....
