Select Parent Member Dialog Box (Analysis Services - Multidimensional Data)
Use the Select Parent Member dialog box in SQL Server Data Tools (SSDT) to select a parent member for a calculated member. You can display the Select Parent Member dialog box by clicking Change in the Calculated Member Form Editor pane on the Calculations tab in Cube Designer.
In certain cases, such as when the hierarchy selected in Tree is defined for an attribute in which no (All) level is specified, there may be no parent member to select.
Select the parent member to use for the calculated member.
