I have made the following mdx query to calculate a running total using some references I found on internet which works when I ran it on management studio.
With member measures.test
as
(
sum([Card Issue date].[YearQuarterMonth].[Calendar Year Month].&[2014]&>>[2014-10]
:[Card Issue date].[YearQuarterMonth].CurrentMember
, [Measures].[LoyaltyMembers])
)
select measures.test on 0,
[Card Issue date].[YearQuarterMonth].[Calendar Year Month] on 1
from [SalesDW_v1]
But the following calculated member I constructed from this gives null values.
CREATE MEMBER CURRENTCUBE.[Measures].[Subscriptions Running Total]
AS
(
sum([Card Issue date].[YearQuarterMonth].[Calendar Year Month].&[2014]&[2014-10]
:[Card Issue date].[YearQuarterMonth].CurrentMember
, [Measures].[LoyaltyMembers])
)
,VISIBLE = 1 , ASSOCIATED_MEASURE_GROUP = 'Demographics',FORMAT_STRING ="#,##0;-#,##0";
I would be glad, If someone could help me locate the problem.
Thank you very much,
Andreas
Looks like your member will work only for October, 2014, because of
[Card Issue date].[YearQuarterMonth].[Calendar Year Month].&[2014]&[2014-10] :[Card Issue date].[YearQuarterMonth].CurrentMember
Since you added it as calc member, when you add it from mdx designer, query gives null, if you also add time axis - it will show values for October till CurrentMember
You should avoid adding such members to cube UI, better embed them as report dataset query.

This is a question regarding SSAS Cubes, MDX formulas and Power BI.
I have a measure with the active members per each month. So when I select for example 2018 it shouldn´t aggregate but return the last available month with active members, and if I break down by month it should give the active members for each month.
So I have this formula which works almost fine if querying in MS Management Studio:
with member [Measures].[Last existing SOCIOS] AS
Max(
EXISTING [DIM FECHA].[Jerarquía].[MES NOMBRE].members,
iif([Measures].[ACTIVOS] = 0,null,
[Measures].[ACTIVOS])
)
select {[Measures].[Last existing SOCIOS]} on columns,
[DIM FECHA].[MES NOMBRE].members on rows
from [cubo_Compromisos]
where [DIM FECHA].[AÑO].&[2018]
I would prefer to have the november value returned at the 'All' level. But this is not my main problem. The real issue is that when I use this measure in Power BI it behaves differently: when selecting multiple months it ignores the selected values and just returns the last value for the whole year.
In the screenshot below I have added the value returned by the KPI Card because that is the value that I want returned:
If I select items like this it does it right, but I need it to select all months, and not just one because I am using this measure along others:
Does anyone know the right MDX function to use or an alternative?

It does the same in a Pivot Table connected to a SSAS Cube.When I add the date dimension to the table it works fine. But when using the date dimension and filtering it without the dimension added as rows it returns the value for the whole year.
The function you are looking at is LastChild. Last Child on the upper level of the hierarchy will return the value you are looking at.
I think that function can be used in the Cube design in SSAS - then this will be the standard behavior. If you want to do it with a query you need to do something like:
SELECT [Date].[Fiscal].[Fiscal Quarter].[Q1 FY 2002].LastChild ON 0
FROM [Adventure Works]
To get the last month of the 1st quater (I used example from microsoft and another post on the subject )
Would much appreciate any help on this.
I have a measure called "Sales" populated with values, however i am trying to turn the "Sales" value to 0, whenever the "Sales Flag" is set to 0.
Important Note: The Sales Flag is based on Date (lowest level of detail).
The difficulty that i am really experiencing and cant get a grip on, is how i am trying the display the MDX outcome.
As explained above, i would want to make the "Sales" value 0 whenever we have a 0 in the "Sales Flag" (which is based on the Date), but when I run the MDX Script I would wan't on the ROWS to NOT display the Date, but instead just the Week (higher Level to Date), as below shows:
I really have spent hours on this and can't seem to understand how we can create this needed custom Sales measure based on the Sales Flag on the date level, but having the MDX outcome display ROWS on Week level.

You need to define the member in the MDX before the select. Something like that:
WITH MEMBER [Measures].[Fixed Sales] as IIF([Sales Flag].currentMember=1,[Sales], 0)
SELECT [Measures].[Fixed Sales] on 0, [Sales Flag] on 1 from [Cube]
I am writing the code without SSAS here so it might not be the 100% correct syntax but you can get the general idea ;)
You can add the iif in the SELECT part but I find creating member to be the cleaner solution.
SELECT IIF([Sales Flag].currentMember=1,[Sales], 0) on 0, [Sales Flag] on 1 from [Cube]
If you have a control over the cube in SSAS you can create a calculated member there and you can access it easier.
Glad to hear if Veselin's answer works for you, but if not...
Several approaches are also possible.
Use Measure expression for Sales measure:
Use SCOPE command for Day level (if it's Key level of Date dimension). If it's not a key level you have to aggregate on EVERY level (week, year etc) to emulate AggregateFunction of Sales measure but with updated behavior for one flag:
SCOPE([Date].[Your Date Hierarchy].[Day].members,[Measures].[Sales]);
THIS=IIF([Sales Flag].CurrentMember = 1,[Measures].[Sales],0);
END SCOPE;
Update logic in DSV to multiply Sales column by SalesFlag. This is the easiest way from T-SQL perspective.
I need to compute the aggregate of Opportunities Count that are active at a time (which is defined by period between start date and closing date) Not just for that period but for over all...
Opportunities Count for 2016 should include the sum of opportunities from NULL : 2015 and those that are closed in 2016:NULL.
Same thing for month and year
I have the following query that works but is giving me incorrect results for quarter, Month, date level. But gives the correct results for Year. I guess it is because of non unique key names in both dimensions
with member [Measures].[cumulative_count]
as
aggregate({NULL:[Time Dimension].[Year-Qtr-Month-Date].currentmember.lag(1) } *
{LINKMEMBER([Time Dimension].[Year-Qtr-Month-Date].currentmember.lead(1),[Opportuntity Close Dt].[Year-Qtr-Month-Date]):NULL}
,[Measures].[Opportunities Count])
SELECT [Measures].[cumulative_count] on columns,
[Time Dimension].[Year-Qtr-Month-Date].[Month].members on rows
from
AdventCube
I guess I am running into an issue with ALL member as specified in the link
http://richardlees.blogspot.com/2011/06/linkmember.html
But to override the ALL member I am running into syntax errors. Could anyone please help?
I've build a MDX calc member that give me the year-to-date (YTD) for budget, however if the user selects multiple months, it returns the total for year. Which I believe is CurrentMember function, but how do it I get the max from the set?
Aggregate(
PeriodsToDate(
[Date].[Fiscal].[Fiscal Year]
,[Date].[Fiscal].CurrentMember
)
,[Measures].[Budget]
)
So when we have a month slicer to select the month, if the end-user selects more then 1 month, then the CurrentMember fails and the parent is used, so the Full Year (FY) is used.
It might be very late to answer this question but hopefully someone else can benefit with the answer.
for this particualr problem you have to create a dynamic set and apply scope to that. check the below MDX.
dynamic set : existing PeriodsToDate(Date].[Fiscal].[Fiscal Year],[Date].
[Fiscal].CurrentMember)
calcualted member : Aggregate( PeriodsToDate( [Date].[Fiscal].[Fiscal Year]
,[Date].[Fiscal].CurrentMember
)
,[Measures].[Budget]
)
apply scope to it scope (Date].[Fiscal].[Fiscal Year],,[Measures].[Budget])
this = aggregate (([dynamic set],],[Measures].[Budget])
end scope
this way u can select a date range without any problem
Kind Regards

My MDX is fledgling at best, and it is a realistic possibility that I don't even know how to phrase my question correctly to search for an answer. Sorry if this is a duplicate.
I have a date/time hierarchy [Dates]:
[Work Date].[Dates].[Year].[Quarter].[Month].[Day]
What I want to do is return the previous 5 years worth of data, for the month of X (let's assume January):
Year Sub Total
2008 645712.11
2009 848075.43
2010 765802.60
However, I'm having trouble restricting the "Year" data, based on the specific month. I have tried this MDX code, but it yields no results at all:
SELECT [Measures].[Sub Total] ON 0,
[Work Date].[Dates].[Year] ON 1
FROM (
SELECT [Work Date].[Dates].[Month].&[01] ON 0
FROM [Data Warehouse])
If I edit the sub-select I can get a specific year, quarter and month... but I only want to restrict the month portion and not the year. I've looked into using an EXCEPT clause, but I run into the same issue. Does that make any sense? I appreciate any help, and am not opposed to reading long articles if it will further my learning / understanding. Thanks!
After your explanation in comments: To get the same child of each hierarchy level you can use the MDX function COUSIN (here the reference on msdn). As documentation said:
Returns the child member with the same relative position under a
parent member as the specified child member.
so in your case your Date dimension has to be complete without missing months or days, so you can write a query like this (I've tested on AdventureWorks)
with member [Measures].[Sub Total]
as (Cousin([Date].[Calendar].[Month].&[2004]&[1], [Date].[Calendar].CurrentMember), [Measures].[Internet Sales Amount]) , Format_string = 'Currency'
Select {[Measures].[Internet Sales Amount],[Measures].[Sub Total] } on 0
,{
[Date].[Calendar].[Calendar Year].&[2002]
,[Date].[Calendar].[Calendar Year].&[2003]
,[Date].[Calendar].[Calendar Year].&[2004]
} on 1
from [Adventure Works]
I've put side by side the total and the sub total for the years. I am considering only these 3 years because they are complete from jan to dec and I can apply cousin operator without problem.
Hope this help!
