Error event in Referenced SubProcess

Hi Experts,

I am using a Referenced Sub Process in Parent process for sending Order line items one by one, where I need to check the response of every message before sending another.

I want to raise an error in Sub process for every error response, and continue with parent process.

Is it possible to configure the above situation? and how.

And does it allow to restart the Suspended Sub process individually.

Appreciate your quick responses with above.

Thanks,

Hussein
