copy Min and Max from Sub-task to Parent

[Daniel Martins]

Hi,

hope someone can help me with this i am really struggling.

We have Tasks in Jira, generally our analytics department is creating a bunch of sub-tasks under those Tasks.

In these Sub-tasks they define a "Start date" as well as an "End date"

now i would like to create a rule that is copying the MIN start date Value from all sub-tasks and write it in the Tasks ticket.

I am using the Automation for Jira Addon but i am unable to find any function that would me allow to do this.

Any help is very much appreciated.

Thanks in advance!

They released this new functionality a few months ago:  

{{issue.subtasks.Start Date.min}}
