Generate data on OTBI report using Costing - Cost Accounting Real Time

We have a requirement for a custom OTBI report that uses Costing - Cost Accounting Real Time. This report should be executed only by a specific custom role - XYZ that is created for this reporting purpose and not anything.

The Custom role has been assigned only with Cost Transaction Analysis Duty (FBI_COST_TRANSACTION_ANALYSIS_DUTY) which secures access to the above subject area. The required data sets have been assigned to the user with this role. Upon testing with the custom role user, the report is not generating any data. Do we need to add any Data security policies to the custom role that will provide access to the data?
