Cancel provisioning process

Hi All,

I'm working on integration with our internal systems, however, I have come to the point where I would like to cancel provisioning due to lack of IP addresses in given subnet. Unfortunately, when I have defined it in lifecycle:

   payload>lifecycleState> phase : PRE

   payload>lifecycleState> state : VMPSMasterWorkflow32.Requested

and exit workflow with an error/exception -> provisioning continues. Is there any way to cancel provisioning process?

I am working on vra7 with vro7. 

Help will be appreciated!
