Edit Virtual Dimension Dialog Box
Use this dialog box to select, from an existing dimension, the new member property on which the virtual dimension will be based.
This dialog box is displayed when, in the Analysis Manager tree pane, you right-click a virtual dimension created in Microsoft® SQL Server™ version 7.0 OLAP Services, and then click Edit. If you perform the same action on a virtual dimension created in SQL Server 2000 Analysis Services, Dimension Editor is displayed. For more information about virtual dimensions created in SQL Server 7.0 OLAP Services, see Virtual Dimensions Created in Version 7.0.
Select the member property on which you want to base your virtual dimension.
