Simple service / reply step

Hi everyone,

i’m trying to understand what’s the matter of the reply step and how to use it? The “Response to” property must mention a receive step in the same process… if I want to reply, it’s to a receive step in another process…

Where to place the receiver using simple service protocol? does it call another process synchronously? how to get the response?

I tried several things but I cant use this.

If someone could help me a bit, I would really appreciate it.

Have a nice day.
