Ytd (MDX)
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 Year level in the Time dimension.
Syntax
Ytd( [ Member_Expression ] )
Arguments
- Member_Expression
A valid Multidimensional Expressions (MDX) expression that returns a member.
Remarks
If a member expression is not specified, the default is the current member of the dimension of type Time (Time.CurrentMember).
The Ytd function is a shortcut function for the PeriodsToDate function where the level is set Year. That is, Ytd(Member_Expression) is equivalent to PeriodsToDate(Year,Member_Expression).
Example
The following example returns the sum of the Measures.[Order Quantity] member, aggregated over the first eight months of calendar year 2003 that are contained in the Date dimension, from the Adventure Works cube.
WITH MEMBER [Date].[Calendar].[First8MonthsCY2003] AS
Aggregate(
YTD([Date].[Calendar].[Month].[August 2003])
)
SELECT
[Date].[Calendar].[First8MonthsCY2003] ON COLUMNS,
[Product].[Category].Children ON ROWS
FROM
[Adventure Works]
WHERE
[Measures].[Order Quantity]
Ytd is frequently used in combination with the CurrentMember (MDX) function to display a running cumulative year-to-date total in a report, as shown in the following query:
WITH MEMBER MEASURES.YTDDEMO AS
AGGREGATE(YTD(), [Measures].[Internet Sales Amount])
SELECT {[Measures].[Internet Sales Amount], MEASURES.YTDDEMO} ON 0,
[Date].[Calendar].MEMBERS ON 1
FROM [Adventure Works]
