How to use Call Activity step by step?

[YovanaSurco]

Hello everyone.

Sorry that I am just learning Camunda and maybe I have a very simple question, but could someone help me how can I link the subprocesses to their parent processes step by step? I understand that with Call Activity is great for it, but I can’t link to the processes I want to call.
Help, please, I would appreciate so much.

Best regards,

Yovana S.

PLNEW.bpmn (2.4 KB) processdecision.dmn (2.4 KB) processSelection.bpmn (…

Difference between Call Activity and Subprocess

Call Activity: A call activity is used to execute another process definition as part of the current process instance. The main difference between a sub-process and a call activity is that the call activity does not share context with the process instance. Process variables are explicitly mapped between the process instance and the call activity. A call activity is visualized as a rounded rectangle with a thick border.
