Epic Progress percent complete


I would like to report using the percent complete that is visible in the Portfolio hierarchy. It appears in the scope report, it appears in the Excel export. How can I get access to this in EazyBI? I have tried this for a custom Measure, but there is no data showing:

[Portfolio Epic].CurrentMember.Get(‘Progress’)

[Portfolio Epic].CurrentHierarchyMember.Get(‘Progress’)

[Portfolio Epic].CurrentHierarchyMember.Get(‘percentageCompleted’)
