Problems using compensation handler in soa11g

Question

Dear All,
I am working on soa 11.1.1.3 ,
i am having problems using compensate activity and also compensation handler inside a scope.
By what i have read on the net,i think its used to roll back a completed process.
In my case, i am making a call from process 1 to process 2 to process 3 and if any one process fails,say process 3,then i want to rollback process 3.
i have put all the 3 process inside different scopes.
Now after the completion of process 3 i used a throw activity to throw an error just to check whether compensate rollsback process 3 or not(roll back only 3 because process 3 is in a different scope and i am using compensate inside the catchall activity of process 3).But what i found was in the audit trail of the instance, process 3 status is completed and it also show's a fault has occured.
what i thought was that process3 would have been completely roll backed and the audit trail would have showed information only till process 2.
am i goin wrong some where or have i interpreted it in the wrong way!!!
Any suggestion's are most welcome!!!
Regards
Ajay.v

Hi,
When you use compensate activity you can only rollback successfully executed scopes and u need to write the compensation logic in the compensate handler of a scope.
