Problem Note 33599: ERROR: Unable to load CLASS entry .CLASS when running batch code containing extension nodes
 |  |  |  |  |
In SAS® Enterprise Miner™ 5.3, after developing an extension node, you can use it in your projects. If you create a diagram flow and then save the flow as a SAS program, you can run this flow as a batch program.
*
For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
However, running any batch program that contains extension node code returns the following error in the log:
ERROR: Unable to load CLASS entry .CLASS.
ERROR: Exception thrown.
exception.server.WORKSPACE.CLASSNAMENOTFOUND,,CodeExport in SASHELP.EMCORE.EMSERVERWORKSPACE.SCL at line 1497.
Program returning prematurely at line 256
AF Program: SASHELP.EMCORE.EMAPI.SCL
This error occurs because the extension node was added after the product was released. In order for nodes developed as extensions to run as batch, they need to be registered in the SASHELP.EMTOOLS data set. The Full Code tab contains code you can run to work around this problem.

This is a sample program that will need to be run in order that extension nodes can be run as part of a batch program. You will need to enter values for the three macro variables.
%let compname=; ****Component name;
%let extensionflag=; ****For example, Code Export node would be CodeExportflag;
%let traincode=; ****Source SAS code file name;
data sashelp.emtool;
set sashelp.emtool end=eof;
retain &extensionflag 0;
if component= "&compname" then &extensionflag = 1;
output;
drop &extensionflag;
if eof then do;
if ^&extensionflag then do;
component= "&compname";
class= "SASHELP.EMCORE.EXTENSION.CLASS";
Traincode= "&traincode";
output;
end;
end;
run;
Creating a batch program within SAS Enterprise Miner that contains extension node's code will produce this error when it is run.
