Create a FIlter where sub task due date are greater than parent due date

[Patrick Poulin]

I try to create a FIlter where sub task due date are greater than parent due date. 

The goal is to use this filter as an agent and notify project lead when this case is true. 

The project lead need to take action asap. !

But I dont understand with JQL how to compare issue due date with parent issue due date. 

Is possible ?
