Embedded Sub Process :
* Embedded SubProcess is also known as Inline Subprocess. It is a subprocess within a Process and cannot be reused outside of the process.
* Embedded Subprocess can access all the process variables where it is defined & also we can add some additional variables to be accessible within that Embedded Subprocess container.
* Embedded SubProcess can also access the group flow elements together to make the business process more readable. Subprocesses are contained as part of the parent subprocess.
Reusable Sub Process :
* Reusable Subprocess is an independent process. It cannot access the parent process variables directly. We need to map the in & out values through Subprocess properties whenever we want to use it. Reusable Subprocesses create business processes that can be called from other business processes.
Reusable processes have the following characteristics :
* It must start with one none start event.
* It can contain multiple end events.
* It can only be called by other business processes.
