Compensate method being called on activity and it shouldn't be called

[Emir Ključanin]

I know the question is not that clear so I'll try to explain my issue as best as I can here.

So I have three activities in my routing slip:

- CreateActiveDirectoryUser Activity

- CreateIdentityServerUser ExecuteActivity

- SendNotificationsToUser ExecuteActivity

and they are in this order in routing slip.

As you can see last two activities are ExecuteActivities, SendNotificationsToUser  is the last activity in routing slip and if it fails it doesn't matter as it is not business critical so I don't have a need to compensate CreateIdentityServerUser. 

The problem is that if SendNotificationsToUser has an exception Compensate method of CreateActiveDirectoryUser is called, and in this scenario I only need CreateActiveDirectoryUser  Compensate method to be called if CreateIdentityServerUser  fails.

I hope I explained my problem clearly.

Is there any solution for this?

Thank you

IF that is the case, and the notification is truly unimportant, it shouldn't be part of the routing slip. If anything, the final activity in the routing slip should publish an event which is then used by a regular consumer to deliver the notification. That way, it can be processed separately, outside of the transaction, with a separate retry policy for that event.

Does that make sense?

By the activity failing, it's indicating that the overall routing slip transaction faulted, and any successful activities should be compensated.

Actually it makes perfect sense :).

Thank you very much for the explanation.
