Instead of Using the [SUB::SAS.IdentityGroups], you may try this . In the Authorization window, select the Group and click on Build the formula. For example the name of Group is XYZ and you want to enable the users in the Group to see only the data of USA then your MDX will be similar to: { [Organization Unit].[Organization Unit].[All Organization Unit], [Organization Unit].[Organization Unit].[All Organization Unit].[GROUP], [Organization Unit].[Organization Unit].[All Organization Unit].[GROUP].[USA], descendants([Organization Unit].[Organization Unit].[All Organization Unit].[GROUP].[USA] )} This support document shows information when there are more than hierarchies, but this even works when there is only one hierarchy in the dimension. http://support.sas.com/kb/37/136.html
