Integration

Hi
For one of our process execution, we would want to trigger another process only when the current running instance id are completed.

Is there a way to track the instance completion using the SOA inbuilt tables of cube_instance and composite_instance.
I saw a state column which has values of 32,34 etc in composite_instance and has value of 5,6 etc for cube_instance

Can anyone let me know any way of tracking a instance id completion so that we can use the result to trigger another process ?

Thanks for all your help in advance
