Hey @RandyJones ,your solution is right , but we have to first store the new part which we created and the change its life cycle state.

The LifeCycleHelper class is used for this. eg

String myState = "PROTOTYPE";

WTPart myPart = <already defined>;

LifeCycleHelper.service.setLifeCycleState((LifeCycleManaged) myPart, State.toState(myState));

This is an issue with your setup. You apparently are not running this on Windchill itself eg: jsp page, workflow, etc.

See this article for running code from a java client:
