Hi there,
This week, we released eazyBI version 8.1, and it includes support for the Worklog dimension in reports.
Now you can add Worklog dimension to the rows and create calculated measure to display a property using the following formula:
[Worklog].CurrentHierarchyMember.Get('Created at')
If this option is not available for you, make sure that Worklog created date is defined as a string dimension. See an example here: Get date worklog was added? (this will not include exact time component though).
Let me know if you have additional questions on this.
Kindly,
Ilze
