I was following the "Create an actor filter" documentation and there is a sample code implementation, When I look&nbsp;at the javadoc,&nbsp;I cannot find the &nbsp;getParentProcessInstanceId() from EngineExecutionContext. Is this renamed to getRootProcessInstanceId()?&nbsp;

Thank you

Hello,

Let's imagine you have a process "Europe"

in this process, you have a call activity to the process "France"

And then, in the process France, a call activity to the process "Grenoble".&nbsp;

In a task in the process Grenoble:

\* the getProcessInstanceId() return the processID in the process Grenoble

\* the ParentProcessInstanceId() is the processinstanceID in the process France

\* the RootProcessInstanceId() is the&nbsp;processinstanceID in the process Europe (this is the case ID the user see)

You can use LongBoard ([http://community.ofelia.com/project/custom-page-longboard](http://community.ofelia.com/project/custom-page-longboard)) to understand and see the different processnstanceid

If you need to access the ParentProcessid, then you have to use the ProcessAPI&nbsp;(hum, saying that, I don't see the way to access the Parent in ProcessAPI - search or a containerId)

Hope this help,

&nbsp;
