In the Entity Detail Report, the option to display base details applies only to a data cell that is a parent member cell. If the option to display base details is not selected, the aggregated amount for the parent cell is displayed as one entry in the report. If you select to display base details, all the information from the base records of the parent cell is displayed.
For example, suppose AllCustom1 is a parent member of the Custom 1 dimension. The base members include Opening, Appropriation, Variances, Increases, Decreases, and Closing. When you select to display base details in the report, the system generates the report with all applicable base records for AllCustom1. If you do not select to display base details, the only the amount for the selected parent cell is displayed; for example, the parent cell AllCustom1 is displayed without any base details.
