Cause:
============
The cause of the issue is when you create the class files, only be.jar file includes the Decision Manager table class file.


Resolution:
============
To use the new class path settings, add the following property settings to the CDD in Studio in Processing Unit tab property. This will ensure that the be.jar file is referenced and used. Alternatively, unzip the be.jar file in your Decision Manager deployment project folder.

&ltproperty name="be.engine.cluster.externalClasses.path"                     value="filepath to RMS class/be.jar"/>
&ltproperty name="be.engine.cluster.externalClasses.classLoader"      value= "true">
