General Ledger - Balance Real Time measures are null

Summary

when using General Ledger - Balance Real Time OTBI subject area all the measures come back null

I have users that are trying to create new OTBI reports from the subject area General Ledger - Balance Real Time. All of the measure data is comes back with no values. They have the General Accounting Manager role so wanted to know what else is required? Is there data access for this as well?  I believe this data comes from essbase so didn't know if data access is a little different?

Thanks -
