Use case
Return the sum of the original estimates of the issues under the epic's parent in hours only in the epic's parent view.
Expression
Create and configure a Smart field using this expression in General parsing mode:
%{ %{issue.issueType} = "Initiative" ? sum( append(fieldValue( {issue.originalEstimate} , union( issuesFromJQL("issuekey in portfolioChildIssuesOf("+ %{issue.key} +")"), issuesUnderEpic(issuesFromJQL("issuekey in portfolioChildIssuesOf("+ %{issue.key} +")")))), [0] )) / 60 : null }
We consider the epic's parent to be a Initiatiave in this expression, but it could differ depending on the Advanced Roadmaps issue type hierarchy.
