How can I restrict the due date of the subtask to be no later than the due date of the parent task?

Hi, 

I use "Risk Validity Date" date field in parent task and "Due Date" in sub-task. I would like to restrict due date of sub-task is not bigger than Risk Validity Date. 

Due date of sub-task is entered when creating the issue. 

 Thanks

Hi @ezgiiklcrsln 

You would need an app like ScriptRunner and add a Behaviour to achieve this. Take a look at this script to get ideas. Although this existing script on the Community is trying to achieve the same thing.
