Handling exceptions at Sub-Process Level

Question

Can we handle exceptions at Sub-Process level itself? Or do we need to transfer the exceptions to the main process and then only the admin user can handle them?

Answer 1

The same thing applies to subprocesses. A subprocess is just a process that has been invoked by another process and the same exception handling rules apply to it.
You can catch exceptions in any process using:
<li> logic at the activity level using a try/catch block
<li> an activity using an Exception transition
<li> a Group in the process using an Exception transition
<li> the process using an Exception Handler
At a minimum, catch the "Others" exception using the Exception Handler. This ensures uncaught exceptions are not sent to the End activity (the default) and the instances are not lost. This simple best practice will save you days of debugging and several calls to customer support to resolve.
