Use of BPM Sub-Process

Question

Hello Experts,
I'm beginner and I wanna know when we will go for BPM sub process.
I know there are two types of process(embedded and reference), but I wanna know when we will go for embedded sub process and for reference sub process.
If possible please share some examples for both the process.
Thanks in advance.

You can use embedded sub-process in BPM when the child process (sub-process) is dependent on the parent process. By this it means that the sub-process cannot execute by itself.
An embedded sub-process cannot have start and end events, although it can have other sub-set of events like timer, escalation and boundary events.
You can use a referenced sub-process when you want to re-use an existing process. A referenced process is an independent process, which can exist of its own. If you want to use that existing process in your BPM Process then you can call it using referenced sub-process. Also make note that your main process will wait till the referenced sub-process completes its flow.
Also if you feel that some process can be re-used by others then you can make it as a separate process and use it in the main process using referenced sub-process. This way others can also re-use the sub-process.
