I have created new issue Epic, the new Epic Issue ticket number is ABC-100,
In this Epic, I have created a new issue Story in "issues in epic",
I have created a custom field "text field" with the name "parent epic", this field I have associated to story level screen.
So when I created a new issue story in "issues in epic", i want to get "parent epic" custom filed value is Epic key(i.e ABC-100) at story level issue.
Kindly help me on this?
