eazyBI imports and use issue own data in reports by default.
eazyBI supports building and working with hierarchies. Default support here includes summing numeric data from a lower level of hierarchy to higher levels on hierarchy. We use issue references in a hierarchy for grouping and summing.
You can use measures related to date, for example, Issues with target end to sum a count of issues with this date up to any higher level. However, we do not support to pass down this value from a higher level to a lower level.
If you would like to access parent dates in the hierarchy, you can access the parent issue itself and the pick the date from it.
Here is an example formula for Epic Target end
[Issue].[Issue].GetMemberByKey([Issue].CurrentHierarchyMember.Get("Portfolio Epic")).GetDate("Target end")
Please check if Portfolio Epic is your property name referencing to Epic level in eazyBI. I used default level names Portfolio Epic we are generating for Portfolio hierarchy as an example. Please check if the Target end is correct and case sensitive name for your date field as well.
