In my cube I have dimension calculated in the following way:
Sum(PeriodsToDate([Year].[Data].[(All)]), [Quantity])
how to change this formula to calculate the sum only to the current day?
The time dimension contains data on future years.
Depending on what you want to do, try the following:
For the sum from start until today:
SUM( { NULL : StrToMember('[Year].[Data].&[' + FORMAT(NOW(),'yyyyMMdd') +']') }, [Quantity] )
Depending on your representation of the day you may need to change the 'yyyyMMdd'-part of FORMAT, for me it is 20180321 for today as of writing this.
For the sum from start until the 'current' selected day (on the rows or the filter):
SUM( { NULL : [Year].[Data].currentmember }, [Quantity] )

I'm trying to do a query that calculate the sum of measures in a specified range of time in a period.
WITH MEMBER
[Measures].[calc] as
SUM (
{ [date.time].[day].CurrentMember.LEAD(-30):[date.time].[day].CurrentMember },
[Measures].[my_value]
)
SELECT NON EMPTY {[Measures].[calc]} ON COLUMNS,
{[date.time].[day].[2014-07-21 00:00:00.0]:[date.time].[day].[2016-07-21 00:00:00.0]} ON ROWS
FROM [my_cube]
this code works, it return to me the sum of the current member plus the last 30 members before it,but I'm looking for a way to subtract instead members(days in this case), months, because not all months have 30 days, there's some way to do this? because if there isn't, for each day of my interval will be needed to do one request to do what I want in my java code
If you you have a hierarchy with day-month relation (say, calendar), you can use the day's parent:
WITH MEMBER
[Measures].[calc] as
SUM (
{ [date.time].[calendar].CurrentMember.LEAD(-30):[date.time].[calendar].CurrentMember },
([date.time].[calendar].CurrentMember.Parent.Lag(1),[Measures].[my_value])
)
SELECT NON EMPTY {[Measures].[calc]} ON COLUMNS,
{[date.time].[day].[2014-07-21 00:00:00.0]:[date.time].[day].[2016-07-21 00:00:00.0]} ON ROWS
FROM [my_cube]
If you don't have the hierarchy, you can use the day key to regenerate it into the month key:
WITH MEMBER
[Measures].[calc] as
SUM (
{ [date.time].[day].CurrentMember.LEAD(-30):[date.time].[day].CurrentMember },
(StrToMember('[date.time].[month].[' + left([date.time].[day].CurrentMember.Properties('Key'),7) + ']').Lag(1),[Measures].[my_value])
)
SELECT NON EMPTY {[Measures].[calc]} ON COLUMNS,
{[date.time].[day].[2014-07-21 00:00:00.0]:[date.time].[day].[2016-07-21 00:00:00.0]} ON ROWS
FROM [my_cube]
Let's assume i have easy table with sales data like:
id shop
id product
date
amount
Can you help me to write MDX query for calculated member to get current period sales ratio to same period of previous year?
For example, if month or quarter selected as one of dimensions.
Let's assume you've a [Time] dimension with [Year], [Month] and [Day] levels.
If
SELECT
[Time].[Jan 2015]:[Time].[Dec 2015] on 0,
[Measures].[Sales] on 1
FROM
[Cube]
Returns the sales for all months of 2015. We can add a calculated measure to get ratio :
WITH
MEMBER [Sales Ratio] AS DivN(
[Sales],
( ParallelPeriod( [Time].[Year], 1, [Time].current ), [Sales] )
SELECT
[Time].[Jan 2015]:[Time].[Dec 2015] on 0,
{[Sales],[Sales Ratio]} on 1
FROM
[Cube]
DivN is icCube specific and allows for dividing being 'empty' safe.
ParallelPeriod is a standard MDX function, that returns previous years month. You could also use Lag(-12), that is 'travelling' backwards in a level 12 times.
current (aka Currentmember) is also standard MDX and allows for retrieving the current value of a hierarchy/ dimension.
In icCube I'd add a function to navigate to the previous year so you can reuse it (and fix one if needed). Like :
WITH
FUNCTION timePrevYear(t_) AS ParallelPeriod( [Time].[Year], 1, t_ )
MEMBER [Sales Ratio] AS DivN(
[Sales],
( timePrevYear( [Time].current ), [Sales] )
SELECT
[Time].[Jan 2015]:[Time].[Dec 2015] on 0,
{[Sales],[Sales Ratio]} on 1
FROM
[Cube]
It's going to be a bit too much but eventually you could add this kind of calculations in what we call in MDX Utility or Stats dimension, so you can even let the end-user select this in a dropdown from a reporting tools. More on this here.
In the models I create for my clients, I sometimes take another route as ic3 has suggested:
Especially when there will be lots of additional calculations on top of these (e.g. year-to-date, inception-to-date, month-to-date etc).
This is:
load the same facts data again, but set as the "load date" the "date" - 1 year (e.g. mySQL: DATE_ADD(,INTERVAL -1 YEAR).
Advantages:
drill through on history is possible
lots of formulas can be added "on top" of these, you always know that the basics are ok
I've been tasked with a rather odd Time intelligence function by my finance group that I'm trying to puzzle out.
I've been asked with creating a measure within our SSAS Cube to allow for seeing previous quarter to date based on how far we are in the current quarter. But instead of seeing a standard idea of days elapsed currently versus days elapsed previously, they would like to see days remaining versus previous days remaining.
What I mean by that is, take 1/22/2015 for example. We have 48 days remaining in our current quarter, which I have by means of a calculated measure. I need to find the corresponding working day from the previous quarter where it is also at 48 days remaining.
At that point I could create a date range with some aggregate functions off of the first date in the previous quarter to the corresponding date found in the above and come up with what they are looking for.
The best idea I've had so far is to possibly do this in the database section itself, by creating a new column that is essentially the calculated number of days remaining but stored. But at that point I'm not sure how to take a calculated measure in SSAS and filter a previous quarter date member to use that property as it were.
Do you have an utility dimensions in your cube? We have one called TimeCalculations. In there we have things such as CurrentValue, MTDValue, PrevEquivMTD, Past7Days .... I think your new logic would fit in with such a dimension.
Here is an example of PrevEquivQTD against AdvWrks that I just had a play with. Guessing this doesn't really help your scenario but I had fun writing it:
WITH
SET [NonEmptyDates] AS
NonEmpty
(
[Date].[Calendar].[Date].MEMBERS
,[Measures].[Internet Sales Amount]
)
SET [LastNonEmptyDate] AS
Tail([NonEmptyDates])
SET [CurrQ] AS
Exists
(
[Date].[Calendar].[Calendar Quarter]
,[LastNonEmptyDate].Item(0)
)
MEMBER [Measures].[pos] AS
Rank
(
[LastNonEmptyDate].Item(0)
,Descendants
(
[CurrQ]
,[Date].[Calendar].[Date]
)
)
MEMBER [Measures].[PrevEquivalentQTD] AS
Sum
(
Head
(
Descendants
(
[CurrQ].ITEM(0).PrevMember
,[Date].[Calendar].[Date]
)
,[Measures].[pos]
)
,[Measures].[Internet Sales Amount]
)
SELECT
{[Measures].[pos],[Measures].[PrevEquivalentQTD]} ON 0
,[LastNonEmptyDate] ON 1
FROM
(
SELECT
[Date].[Calendar].[Date].&[20050111]
:
[Date].[Calendar].[Date].&[20080611] ON 0
FROM [Adventure Works]
);
Your Date is 1/22/2015. You want the Same Date in Previous Quarter which would be 8/22/2015.
If this is what you want, you will have to use MDX function ParallelPeriod as shown in sample below. Please replace it with your own Dimensions and Cube.
Select
ParallelPeriod
(
[Date].[Calendar Date].[Calendar Quarter], -- Level Expression
1, -- Index
[Date].[Calendar Date].[Date].&[20150122] -- Member Expression
) On 0
From [Adventure Works]
If you want the same date in the following quarter, then replace index 1 with -1.
Cheers
I want to create a calculated member. I have a time dimension hierarchy" YQM", which has Year/Quarter/Month. The calculated member should find YTD till the current month. However, the value of current month will come from database.
I have created a attribute, "CP" which returns the current month value.
Please tell me how to create the calculated member. Please note "CP" is not in the same hierarchy YQM.
I don't understand why you are using Aggregate. So, I will assume that it is there for some purpose, which you have't clarified. Now, if the members of [YQM].[Month] and [Dim].[CP] are of the same format, then you can try the code below:
Aggregate(
PeriodsToDate([Dim].[YQM].[Month].MEMBERS,
FILTER([Dim].[YQM].[Month].MEMBERS,
[YQM].[Month].CURRENTMEMBER.member_value = [Dim].[CP].FirstChild.member_value)
)
)
Why not try playing with the function YTD. The following should give you the monthly amount in the first column of data and then the YTD amount in the next column:
WITH MEMBER [Measures].[YearToDate] AS
AGGREGATE(
YTD()
,[Measures].[someMeasureInCube]
)
SELECT
{
[Measures].[someMeasureInCube],
[Measures].[YearToDate]
} ON 0,
[Dim].[YQM].[Month].MEMBERS ON 1
FROM [yourCube]
My situation is as following:
This is a Powerpivot solution developed in Excel 2013 (32-bit).
I got a transaction table containing transactions with an amount, a category and a posting date. What I would like to to is to present a number of different calculations depending on the time frame.
Sum of amount of current day of import (all the transations with the latest posting date available).
Sum of amount Month-to-date (the current month of the latest transaction)
Sum of amount same period last month (Month-to-date minus one month)
Sum of amount last month (the totals for whole last month)
So, idea is to create a "Current day" measure as a stand point for all the other measures.
[Current day] = LASTDATE('TransactionTable'[Posting Date])
Before summarizing things I wanted to create measures that would represent the start and end date for each period (to display in the report and to make easier measures), this is where I run into trouble.
[First day of current month] = STARTOFMONTH([Current Day])
Gives me the error: "A function 'CALCULATE' has been used in a True/False expression that is used as a table filter expression. This is not allowed."
And with this I would like to end up with something like this for current month:
[Sum of amount current month] = CALCULATE(SUM('Transactiontable'[Amount]);DATESBETWEEN('DateTable'[Date]; [First day of current month];[Current day]))
And this for previous month total:
[First day of previous month] = DATEADD([First day of current month];-1;MONTH)
[Last day of previous month] = EOMONTH([Current day];-1)
CALCULATE(SUM('Transactiontable'[Amount]);DATESBETWEEN('DateTable'[Date]; [First day of previous month]; [Last day of previous month]))
It feels like I am not using the measures the "right" way... Basically I want to create dynamic measures that will change the timeframe depending on what the latest posting date is in the transaction table. Is this the way to go at all?
Thanks guys,
First you need to use ALL()
You were pretty close - the trick to getting [CurrentDate] right is use of the ALL() function. This handy function overrides any filter conditions you have.
So let's look at your [CurrentDate] measure that uses LASTDATE('TransactionTable'[Posting Date]). If your pivot table has months as row labels, this will happen:
The row context alters the output of [CurrentDate]. Not what we want. So you need to override the filter condition, like this.
[CurrentDate] = CALCULATE(LASTDATE(TransactionTable[Posting Date])
,ALL(TransactionTable)
)
Then you need FILTER()
Then to sum the amount for [CurrentDay] we do this:
[SumAmountCurrentDay] = CALCULATE([SumAmount]
,FILTER(TransactionTable
,TransactionTable[Posting Date]=[CurrentDay]
)
)
We need to use FILTER() because it's a more complicated criteria than CALCULATE can handle by default. FILTER() explicitly tells CALCULATE() which table it needs to filter on - although it might be obvious to us, it isn't to PowerPivot.
Here are the rest of the formulas you need, of varying complexity but mostly reusing functions you've listed above, plus ALL() and FILTER().
[FirstDayOfCurrentMonth]
=CALCULATE(STARTOFMONTH(TransactionTable[Posting Date])
,ALL(TransactionTable)
,FILTER(TransactionTable
,TransactionTable[Posting Date]=[CurrentDay]
)
)
[SumAmountCurrentMonth]
=CALCULATE([SumAmount]
,DATESBETWEEN(DateTable[Date]
,[FirstDayOfCurrentMonth]
,[CurrentDay]
)
)
[FirstDayOfPrevMonth]
=CALCULATE(STARTOFMONTH(TransactionTable[Posting Date])
,ALL(TransactionTable)
,FILTER(TransactionTable
,TransactionTable[Posting Date]=
CALCULATE(dateadd(LASTDATE(TransactionTable[Posting Date])
,-1
,month
)
,ALL(TransactionTable)
)
)
)
[LastDayOfPrevMonth]
=CALCULATE(ENDOFMONTH(TransactionTable[Posting Date])
,ALL(TransactionTable)
,FILTER(TransactionTable
,TransactionTable[Posting Date]=
CALCULATE(dateadd(LASTDATE(TransactionTable[Posting Date])
,-1
,month
)
,ALL(TransactionTable)
)
)
)
SumAmountPrevMonth
=CALCULATE([SumAmount]
,DATESBETWEEN(DateTable[Date]
,[FirstDayOfPrevMonth]
,[LastDayOfPrevMonth]
)
)
