Hello Laskmi,
Yes you can configure workflow to security team and they can reject the workflow.
but, depend on you configuration.
if a workflow goes to escape path for any other reason.. if target system is down or user has to resubmit. just 1 example, escape path is very useful to avoid re submission of request.
since it has come after all approval process if any problem related either system of anything the user has to go all over again.
what if the root cause of error is not fixed and user has to resubmit every time.
my advice if any issue request goes to escape path, get the issue fixed and reroute the ticket to appropriate stage for provisioning.
Regards,
Prasant
