Could you elaborate the some more about the "Future event to happen", DO you have any estimated date in future so that you can apply logic based on it, for ex If you want some process to be happen after 3 months or a year, then from current days you can implement your logic based on that.
For this you have to use Agent which is responsible to monitor dates and perform the required logic.
I wish I was clearer earlier. To put it in simple words - I am looking for a way to verify a process for its efficiency. Earlier process simulator used to help here, now that we dont have process simulator, what would be the way for this?
