Importance of ProcessEngineInput.xml in Process Definition Tool of CSA

Hi ,,

I have a doubt regarding adding a new OO process engine to CSA.

If we are defining <ooengine> tag in HPOOInputInfo.xml , Do we also need to add a new process engine in ProcessEngineInput.xml as well ?

Main Issue : I see below issue while trying to add a new OO engine .
