Returns a set of sibling members from the same level as a given member, starting with the first sibling and ending with the given member, as constrained by the Quarter level in the Time dimension.
If a member expressionis not specified, the default is the current member of the first hierarchy with a level of type Quarters in the first dimension of type Time in the measure group.
The Qtd function is a shortcut function for the PeriodsToDate (MDX) function whose level expression argument is set to Quarter. That is, Qtd(Member_Expression) is functionally equivalent to PeriodsToDate(Quarter_Level_Expression, Member_Expression).
The following example returns the sum of the Measures.[Order Quantity] member, aggregated over the first two months of the third quarter of calendar year 2003 that are contained in the Date dimension, from the Adventure Works cube.
WITH MEMBER [Date].[Calendar].[First2MonthsSecondSemester2003] AS Aggregate( QTD([Date].[Calendar].[Month].[August 2003]) ) SELECT [Date].[Calendar].[First2MonthsSecondSemester2003] ON COLUMNS, [Product].[Category].Children ON ROWS FROM [Adventure Works] WHERE [Measures].[Order Quantity]
