I have spent a lot of time solving this issue, but no success yet.
I have a Date dimension called [Dim Date] and in this table I have a [Date Key] which contains all the dates from '2013-07-01' to '2016-12-31'. I also have a measure called [Retail Revenue] which is a decimal number for that date. So far so easy!
We are a retail Calendar and all our calculations/comparisons are based on a retail calendar (which is a customized table in DW).
The date hierarchy in this calendar is as below (please see the screenshot):
-- retail year (e.g. 2017)
---- retail half year (e.g. 2017-H1)
------ retail quarter year (e.g. 2017-Q1)
-------- retail month (e.g. 201702) (months from 201701 to 201712)
---------- retail week (e.g. 201708) (weeks from 201701 to 201752)
------------ date key (e.g. 2016-08-22)
SCREENSHOT
We also have an attribute called "Retail Last Year Date" which shows the equivalent date of last calendar date (e.g. 2015-08-24 in the screenshot).
I need to have a calculated member showing the "Retail Revenue" for last year (based on the attribute "Retail Last Year Date"), next to the regular "Retail Revenue" for [date key].
I tried to use ParallelPeriod and Scope, and could not get the numbers properly. Probably an easy task but I am not a hero in mdx unfortunately!
Will be more than thankful if anyone please can help me out with this.
Thanks

Hopefully this helps.
This is against AdvWrks. I've created a query scoped custom measure that gets the internet sales from the year before:
WITH
MEMBER [Measures].[Internet Sales Amount LastYear] AS
(
ParallelPeriod
(
[Date].[Calendar].[Calendar Year]
,1
,[Date].[Calendar].CurrentMember
)
,[Measures].[Internet Sales Amount]
)
SELECT
{
[Measures].[Internet Sales Amount]
,[Measures].[Internet Sales Amount LastYear]
} ON 0
,
[Date].[Calendar].[Date].&[20070121]
:
[Date].[Calendar].[Date].&[20070127] ON 1
FROM [Adventure Works];
Here are the results:
Thanks for your response, but I didn't get how it uses the dimension property? because my calendar is customized and I cannot assume the last year calendar date is the same as this year. I have to read it from the dimension property "Retail Last Year Date").
Thanks

We have a relative date dimension in our cube that has member values This Year and Last Year as an example.
The user uses this set on columns against sales so they can look at Sales for this year and the same period last year.
The problem comes when they are using the Calendar Date filter to only select values for this month. If the user selects just this month, then the Last Year member disappears.
Is there a way (perhaps with scope statements) that I can tell SSAS: If the user is using these attributes and they select a specific month (or other level), then use ParallelPeriod to implicitly include the same members for the previous year so that they can see the last year sales?
If not, without using calculated members (I have so many measures that I don't want to have to duplicate them), is there a way using dimensions to show a last year value even if the user selects this year in the date dimension?
There are a few options here...
I would just add a new Calculated Member to an existing dimension,i'll add it to a Pseudo-Dimension [Time Period] dimension with something like this:
(i'm pretty sure you need to add it to an existing Hierarchy. I'll assume [Relative Time])
CREATE MEMBER [Time Period].[Relative Time].[Last Year]
AS NULL
, VISIBLE=1;
SCOPE(
DESCENDTS([Time].[YearMonthDate].[Year].MEMBERS,,AFTER)
,[Time Period].[Relative Time].[Last Year]
);
THIS = AGGREGATE(
PARALLELPERIOD(
[Time].[YearMonthDate].[Year]
,1
,[Time].[YearMonthDate].CURRENTMEMBER
)
,[Measures].CURRENTMEMBER
);
END SCOPE;
I have a Cube with a Date dimension hierarchy (Year,Semester,Quarter,Month,Day).
There are 2 measures available in the datawarehouse.
[AUD DLY] : Daily numbers
[AUD YTD] : Daily incremental YTD numbers
Hierarchy is as follows
Date - Dimension
Financial - Hierarchy
Year - [Date].[Financial].[Year]
Semester - [Date].[Financial].[Semester]
Quarter - [Date].[Financial].[Quarter]
Month - [Date].[Financial].[Month]
Day - [Date].[Financial].[Day]
Measures [AUD DLY]
Measures [AUD YTD]
I need to add a MTD field in the measures such that when the business select a particular date on their slicer in excel for e.g., 3 March 2016, MTD should be calculated as either of the following ways :
1) [AUD MTD] should be calculated by subtracting [AUD YTD] on
last day of previous month from the current selected date.
So if we select 3 March 2016 then
[AUD MTD] = [AUD YTD] on 3 March 2016 - [AUD YTD] on 29 Feb 2016
OR
2) [AUD MTD] should be calculated by adding the [AUD DLY] from first day
of the current month until the selected date in that month.
So if we select 3 March 2016 then
[AUD MTD] = SUM ([AUD DLY] from 1 March 2016 to 3 March 2016)
I created a New Calculated Member from Calculations tab in the Cube designer in the BIDS 2010. The MDX query is below. However when I try to browse the cube the [AUD MTD] values are only returning nulls.
Can someone please help what am I doing wrong ?
CREATE MEMBER CURRENTCUBE.[Measures].[AUD MTD]
AS Aggregate
(
PeriodsToDate
(
[Date].[Financial].[Month]
,[Date].[Financial].CurrentMember
)
,[Measures].[AUD DLY]
),
FORMAT_STRING = "Currency",
NON_EMPTY_BEHAVIOR = { [AUD DLY] },
VISIBLE = 1 , DISPLAY_FOLDER = 'AUD Values' , ASSOCIATED_MEASURE_GROUP = 'Measures' ;
Also the business would be using the new calculated measure in excel using the Slicer, they want to select any date and be able to view the MTD value for that month.
Also can someone please help with MDX query for both methods (1) and (2) ?
Your help much appreciated.
I think the problem with your quoted code (method 2) is that [Date].[Financial].CurrentMember must be at a level at or below the [Date].[Financial].[Month] level. Otherwise PeriodsToDate returns an empty set.
So the problem is not in your calculated member definition, but somewhere in the query in which it's being used. In that query, [Date].[Financial].CurrentMember may be returning a member at a level above Months. Hard to see without seeing the query itself.
Method (1) is more fiddly. You can get the last day of the previous month with
Ancestor([Date].[Financial].CurrentMember,[Date].[Financial].[Month]).PrevMember.LastChild
but you'd have to build in some logic for days in the first month of the financial year, which would otherwise subtract the value for a previous fin year from this year's YTD value. So I'd recommend method (2).
As far as I know selecting a date (I mean a date, not a month) in the Excel slicer will make that date the .CurrentMember. I'm a bit hesitant because Excel does generate some deeply bizarre MDX sometimes.
EDIT: Another possible problem is a hierarchy mismatch. You can select a perfectly good Day in a date hierarchy, but if it isn't in exactly the hierarchy you specify in your calculated member definition, you can get weird results. IMHO more recent versions of SSAS encourage a proliferation of attribute hierarchies and multiple "real" hierarchies, making this a real problem.
As a test can you please add this very simple measure to make sure that currentmember is behaving as expected:
CREATE MEMBER CURRENTCUBE.[Measures].[AUD MTD]
AS [Date].[Financial].CurrentMember.member_caption
If when you use the above all it returns is the All member then you know something is wrong.
You need to double-check your relationships and datatypes used within your date hierarchies as this is often the reason for time calculation problems.
This is an alternative to your measure but I suspect if the original script is not working then neither will this...
CREATE MEMBER CURRENTCUBE.[Measures].[AUD MTD]
AS SUM
(
MTD([Date].[Financial].CurrentMember)
, [Measures].[AUD DLY]
)
We want to show current periods sales versus previous period sales.
To show the previous period we make use of a date dimenion table and the following calculation:
CALCULATE(SalesValueGross; DATEADD(Date[Date]; -1; YEAR))
Unfortunately somehow it shows minor (decimal) differences when comparing years.
The difference get's bigger when we slice to months.
Another issue we have is that this calculation does not seem to work when comparing (for example) week 1 - 2015 with week 1 - 2014.
Any help is greatly appreciated!
When I want to get prior calendar year sales, I use the a formula such as the following:
Cal Prior Yr Sales:=if(HASONEVALUE('Sale Date'[Calendar Year]),
Calculate([Total Sales],
PREVIOUSYEAR('Sale Date'[Date])),BLANK())
The HASONEVALUE just ensures that there is only one year selected so it will know the correct previous year to retrieve.
You can make a series of calculations that will let you use one calc that determines what level of the date hierarchy you are in (assuming you have the fields available in your date table). Here is something I've used in the past, with a fiscal calendar that was different from the normal calendar.
First, the base calculations:
Sales Same Week Prior Year:=
CALCULATE([Total Sales],Filter(All('Sale Date'),
'Sale Date'[Week Key] = max('Sale Date'[Same Week Last Year])))
Sales Same Month Prior Year:=CALCULATE([Total Sales], Filter(All('Sale Date'),
'Sale Date'[Month Seq] = max('Sale Date'[Month Seq])-12))
Sales Same Quarter Prior Year:=CALCULATE([Total Sales], Filter(All('Sale Date'),
'Sale Date'[Quarter Seq] = max('Sale Date'[Quarter Seq])-4))
Sales Prior Year:=CALCULATE([Total Sales], Filter(All('Sale Date'),
'Sale Date'[Fiscal Year] = max('Sale Date'[Fiscal Year])-1))
You can hide all of those calculations and then create one last calculation and leave it visible:
Sales Same Period Last Year:=
if(HASONEVALUE('Sale Date'[Week Key]), [Sales Same Week Prior Year],
if(HASONEVALUE('Sale Date'[Month Key]),[Sales Same Month Prior Year],
if(HASONEVALUE('Sale Date'[Quarter Key]),[Sales Same Quarter Prior Year],
if(HASONEVALUE('Sale Date'[Fiscal Year]), [Sales Prior Year], BLANK()))))
You may need to add a couple of calculated fields to your date table to make it work. I have fields for: [Same Week Last Year], [Month Seq], [Quarter Seq]. Same week last year is an integer field that is yyyyww. Month Seq and Quarter Seq are just autoincrementing integers in chronological order that do not repeat.
My formula for same week last year is
=if('Sale Date'[Week Nbr] = 53, (('Sale Date'[Fiscal Year]-1) * 100) + ([Week Nbr]-1),
(('Sale Date'[Fiscal Year]-1) * 100) + ([Week Nbr]))
I did the sequence numbers in my SQL view, which is the source for the date date. As an example, if my date table starts at 1/1/2010, the month seq for Jan 2010 is 1 and the month seq for Jan 2011 is 13. The quarter seq for Q1 2010 is 1 and the quarter seq for Q1 2012 is 9.
http://www.daxpatterns.com/time-patterns/ is a good read for this topic.
I am trying to put together an SQL statement that returns the SUM of a value by Year for several selected years, but on a year to date basis. In other words, running the report by selecting years I need the value for the selected years on a year to date basis. This could be something like this: By selecting the years 2015, 2014 until 2010 the Report should give 2015 value ytd of 25.02.2015, 2014 ytd of 25.02.2014 and so on.
Yet I only figured out how to select the Dates for each year to date value manually., but clearly the I was thinking. However, I was hoping to have some of this work handled with my SQL Statement using the selected years Parameter and add month and day somehow.
Has anyone ever tackled this type of problem with an SQL statement, and if so, what is the trick that I am missing?
My current sql statement for ytd data is similar to the following:
SELECT NON EMPTY { [Measures].[Sales Turnover YTD], [Measures].[Order Intake YTD] } ON COLUMNS FROM ( SELECT ( STRTOSET(#DateDate, CONSTRAINED)
This works perfectly for the one year, but still I am seeking the solution for several years.
As described above my desired result would be: after choosing several fiscal years (e.g. 2010-2015) I will get following values:
2015 Sales Turnover YTD Order Intake YTD on date today
2014 Sales Turnover YTD Order Intake YTD on date today one year ago
and so on..
Here is a script against AdvWrks that calculates the equivalent YTD totals for each of the years ON ROWS:
WITH
SET [NonEmptyDates] AS
NonEmpty([Date].[Calendar].[Date].MEMBERS)
SET [LastNonEmptyDate] AS
Tail([NonEmptyDates])
SET [SetDaysInCurrentYear] AS

SELECT

[Measures].[Internet Sales Amount]
,[Measures].[EquivYTD]
} ON 0
,[Date].[Calendar].[Calendar Year] ON 1
FROM [Adventure Works];
In my SSAS Cube, I have a measure called [Sales Total]. What I want to do is to create another measure that would give me the lowest sales figure in the last 6 months. I want this to be a moving minimum, calculated as the min of sales of every time period from the present month to 6 months back.
I wrote my MDX statement but it produces an error and I have hard time trying to figure out why. It is something to do with aggregating Date dimension members into a filter aggregate.
When i choose a single month member from the Date hierarchy, it returns the correct value. When I select multiple members from the hierarchy, as seen below, it errors out.
Any kind of help is appreciated.
WITH
MEMBER [Measures].[Min Sales Total Rolling 6 months] as '(MIN([Date].[Fiscal Month Hierarchy].currentmember.lag(6):[Date].[Fiscal Month Hierarchy].currentmember,[Measures].[Sales Total]))'
MEMBER [Date].[Fiscal Month Hierarchy].[FilterAggregate] as
'AGGREGATE({
[Date].[Fiscal Month Hierarchy].[Quarter].&[20141].&[201310],
[Date].[Fiscal Month Hierarchy].[Quarter].&[20141].&[201311],
[Date].[Fiscal Month Hierarchy].[Quarter].&[20141].&[201312],

[Date].[Fiscal Month Hierarchy].[Quarter].&[20143].&[201404],
[Date].[Fiscal Month Hierarchy].[Quarter].&[20143].&[201405],
[Date].[Fiscal Month Hierarchy].[Quarter].&[20143].&[201406],
[Date].[Fiscal Month Hierarchy].[Quarter].&[20144].&[201407]
})'
SELECT {
[Measures].[Min Sales Total Rolling 6 months]} ON AXIS(0)
FROM [My Cube]
WHERE ([Date].[Fiscal Month Hierarchy].[FilterAggregate])
As explained in this blog by one of the SSAS developers already many years ago, multi select does not work with CurrentMember. You should use
MEMBER [Measures].[Min Sales Total Rolling 6 months] as
MIN(Tail(EXISTING [Date].[Fiscal Month Hierarchy].[Fiscal Month Hierarchy].Members).Item(0).Item(0).lag(6)
:
Tail(EXISTING [Date].[Fiscal Month Hierarchy].[Fiscal Month Hierarchy].Members).Item(0).Item(0),
[Measures].[Sales Total])
instead.
EXISTING gets the set of all selected members. This is needed as there is no single CurrentMember. Then Tail gets the set consisting of the last of these members, Item(0).Item(0) converts that single element set to a member.
