Questions & Answers

Hi,
I want to count all issues in an epic. Issues have child issues on several levels. I want to count them all. How do I do this?
I do not have the option to create a calculated dimension as I do not have system admin rights.

[Issue].CurrentHierarchyMember.Children gives me the number of children, but those children do also have children. How can I fetch those?
