find Jira child elements planned at later date

[boellner boellner]

Hello,

I have a structure of 

-Project Feature
--one or many Epic
---one or many Story

All elements are planned for a fixed version.
A higher element shall not end before any element in the tree.

Now I need to find a query to find all of those elements where one of the children is planned for a later date than itselve or maybe easier

find all elements that are planned later than their direct parents. 
Then we have a planning fault.

How would I do this in JQL?

Hi @boellner boellner ,

I don't think this is possible with JQL.

But for example Advanced Roadmaps can visually show you this information and help you fix it.

does advanced roadmaps work with fix version without start and end dates?

[Hana Kučerová]

@boellner boellner Advanced Roadmaps use fix versions as milestones in the Roadmap. So, if fix versions don't have dates, you won't see any milestones, but still you will be able to see the dates for all the issues in the hierarchy and which of them have invalid dates (I expect that in issues you use dates like Start date and End date or something like this to set the dates).
