I need to make changes to SoCDefinitionSNC Script Include but unable to do so due to read-only policy.    Insert and Stay makes another copy but still in read-only status, 

Thanks in advance.

That is the encapsulating code, you should be able to customize / clone the script include which implements that class / extends that class. 

There should be a script include named "SoCDefinition", which is the customization point for SoCDefinitionSNC script include.

You would be able to clone that script include and can then override the functions from the extended class. You can then instantiate the implementation class and use its methods.

Thanks for your quick response.  This gives me a good start point to try it out.  I will share my journey on this. 

Much appreciated.
