Cumulative Sum via Calculated Measure
-
Hey all I'm hoping you can help me with an MDX problem I am having. I will use adventure works for this example. Basically I have been asked to create a calculated measure in the cube that will display a cumulative or rolling sum of another measure. I have found quite few solutions but all of them use a specific dimension such as date with YTD in the SUM but I was hoping to create a measure that was not dependent on any specific dimension.
The simplest MDX I could find is in the example below. While this works in MDX on the fly, I can't use it in Excel in any other dimension besides the product line. I was hoping there was a way to make it dynamic so that it would provide the cumulative sum no matter what dimensions are dropped on.
I was thinking that i would have to somehow use the Descendants function with a specified Axis but my knowledge of MDX is so limited that I am probably way off. Any ideas?
with member [Measures].[Running total] asSum(null : [Product].[Product Line].CurrentMember, [Measures].[Internet Sales Amount]),Format = "Currency"select {[Measures].[Internet Sales Amount],[Measures].[Running total]} on 0,[Product].[Product Line].[Product Line].Members on 1from [Adventure Works] -
Something like this would work:
[Code="Other"]
WITH MEMBER [C]
AS
SUM(NULL:Axis(1).Item(0).Item(Axis(1).Item(0).Count-1).Hierarchy.CurrentMember, [Measures].[Your Measure])
SELECT
{[Measures].[Your Measure], [c]} ON 0,
[Your Dimension].[Your Hierarchy or Attribute] ON 1
FROM
[Your Cube]
[/code]
Hope that helps

Please,
Help me.
With a dimension works.
If you use two attributes of the same dimension:
Year;
Month.
Does not work.
Example 01:
WITH
MEMBER [Measures].[SALDO_INICIAL] AS SUM(NULL:Axis(1).Item(0).Item(Axis(1).Item(0).Count-1).Hierarchy.PREVMEMBER, [Measures].[QTDE_TOTAL_ENTRADAS] - [Measures].[QTDE_TOTAL_SAIDAS])
MEMBER [Measures].[SALDO_FINAL] AS SUM(NULL:Axis(1).Item(0).Item(Axis(1).Item(0).Count-1).Hierarchy.CurrentMember, [Measures].[QTDE_TOTAL_ENTRADAS] - [Measures].[QTDE_TOTAL_SAIDAS])
SELECT
{
[Measures].[SALDO_INICIAL],
[Measures].[QTDE_TOTAL_ENTRADAS],
[Measures].[QTDE_TOTAL_SAIDAS],
[Measures].[SALDO_FINAL]
} ON 0,
[DATAS].[MES].[MES] ON 1
FROM
[Model]

Example 02:
WITH
MEMBER [Measures].[SALDO_INICIAL] AS SUM(NULL:Axis(1).Item(0).Item(Axis(1).Item(0).Count-1).Hierarchy.PREVMEMBER, [Measures].[QTDE_TOTAL_ENTRADAS] - [Measures].[QTDE_TOTAL_SAIDAS])
MEMBER [Measures].[SALDO_FINAL] AS SUM(NULL:Axis(1).Item(0).Item(Axis(1).Item(0).Count-1).Hierarchy.CurrentMember, [Measures].[QTDE_TOTAL_ENTRADAS] - [Measures].[QTDE_TOTAL_SAIDAS])
SELECT
{
[Measures].[SALDO_INICIAL],
[Measures].[QTDE_TOTAL_ENTRADAS],
[Measures].[QTDE_TOTAL_SAIDAS],
[Measures].[SALDO_FINAL]
} ON 0,
(
[DATAS].[ANO].[ANO],
[DATAS].[MES].[MES]
) ON 1
FROM
[Model]

This solution was very helpful for me, but hit in a second obstacle, when realize a filter in the dimension of fear the accumulated value changes, needs to the filter not interfere to that extent. Can help me?
