I have requirement for cancelling a request/instance from the request's reco

We implement cancelling of processes normally using messaging. But it depends a bit on how the exact requirements are.

Hi Parvez,

You can create a related action for cancelling a request, where you can use send message node to set some values in your master process (the actual process for handling request workflow). Use a receive message node in the master process to cancel the request.

Thanks for the response I was thinking along the same line.
