In FAW(FDI) Data Validation Tool, we don't have any option to validate the metrics present under 'Financials - AR Aging' subject area. We are unable to properly establish that the source data(Fusion OTBI) matches with the data present in the 'Financials - AR Aging' subject area. It would be helpful if the subject area is included with the others as currently we don't have any method to completely validate the total data for the metrics.
