I have this table
I would like to create measurement get the last traded value for each day. E.g.
How the DAX query should look like?
You have to create two measures. One for the last time in each date and another to get the value for that date and time.
Last Time :=
CALCULATE(MAX([Time]),FILTER('Table',[Date]=MAX([Date])))
Last Traded Value =
CALCULATE (
MAX ( 'Table'[Traded Value] ),
FILTER ( 'Table', [Date] = MAX ( [Date] ) && [Last Time] = [Time] )
)
Then add Date column to rows and Last Time and Last Traded Value measures to Values pane in a pivot table.
Let me know if this helps.
For example:
DEFINE
VAR TableTMP =
ADDCOLUMNS ( 'Table', "DateTime", [Date] + [Time] )
EVALUATE
SUMMARIZE (
NATURALINNERJOIN (
TableTMP,
SUMMARIZE (
GROUPBY ( TableTMP, [Date], "DateTime", MAXX ( CURRENTGROUP (), [DateTime] ) ),
[DateTime]
)
),
[Date],
[Time],
[Traded Value]
)
With the new window functions in DAX, I think this can be simplified to
Last Traded Value =
CALCULATE (
MAX ( 'Table'[Traded Value] ),
INDEX (
1,
ORDERBY ( 'Table'[Time], DESC ),
PARTITIONBY ( 'Table'[Date] )
)
)

I am looking for SSMS (t-SQL) query to return info from the max updated_at row when date in column 1 = [updated_at] is < date in column 2 = [date]. Sometimes candidate_id has more [updated_at] ids, I want the query to return the latest [updated_at] if [updated_at] < [date].
So far I have following, but it only return info for max id and date in column 1 < date in column 2 not when. It doesn't return info if max [updated_at] is > [date]. Hope this make sense
SELECT
[candidate_id],
[date],
[updated_at]
[updated_by_id],
[user_id],
[summary],
[id]
FROM tmpacl1
WHERE EXISTS (
SELECT tmpacl1.id
FROM (
SELECT [candidate_id],
[date],
[updated_at],
[updated_by_id],
[user_id],
[summary],
[id]
FROM TPacl
WHERE (
updated_at = (
SELECT MAX(updated_at) AS TPMax
FROM TPacl_1
WHERE (candidate_id = TPacl.candidate_id)
)
)
AND ( [updated_at] < [date])
) AS TPacl_2
WHERE (tmpacl1.id = id) AND tmpacl1.candidate_id = candidate_id)
Thank you in advance
Sale Type is an attribute and is returning a Single Value error.
This expression works great in SQL but will not work here.
If ( [Sale Type] = "Upsell"
&& [Current Name] = "SaaS"
&& DATEDIFF ( [StartDate],[EndDate],Day ) + 1 > 364,
SUM ( [ARR] ),
SUM ( [TotalPrice] )
)
Trying to calculate YTD for several dates in DAX STUDIO according to https://www.daxpatterns.com/time-patterns/ guide
I've created a measure in my model, which gets the job done when I use Date Dimension and calculates YTD for every date
CALCULATE (
[Sales Amt],
FILTER (
ALL ( 'Date' ),
'Date'[Year] = MAX ( 'Date'[Year] )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
But when I'm trying to reproduce the same result using DAX Studio, I get correct result only when I filter CALCULATETABLE for a certain date
This code works perfectly:
EVALUATE
CALCULATETABLE(
ADDCOLUMNS (
VALUES ( 'Date'[Date] ),
"YTD", CALCULATE (
[Sales Amt],
FILTER (
ALL ( 'Date' ),
'Date'[Year] = MAX ( 'Date'[Year] )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
)
,
'Date'[Date] = DATE(2018,5,1)
)
This code is expected to return YTD for every date in rows, but, unfortunately it doesn't. What am I doing wrong?:
EVALUATE
CALCULATETABLE(
ADDCOLUMNS (
VALUES ( 'Date'[Date] ),
"YTD", CALCULATE (
[Sales Amt],
FILTER (
ALL ( 'Date' ),
'Date'[Year] = MAX ( 'Date'[Year] )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
)
,
'Date'[Date] >= DATE(2018,5,1)
)
The only difference is = vs >=, but I get empty result for all the rows
Nothing is wrong with the way you defined your measure.
However, when testing the measure, you should try to write your DAX query in a way similar to what client tools like Power BI would do:
EVALUATE
SUMMARIZECOLUMNS(
'Date'[Date],
FILTER('Date', 'Date'[Date] >= DATE(2018,5,1)),
"YTD", CALCULATE (
[Sales Amt],
FILTER (
ALL ( 'Date' ),
'Date'[Year] = MAX ( 'Date'[Year] )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
)
or even better:
DEFINE MEASURE 'Sales'[Sales Amt YTD] = CALCULATE (
[Sales Amt],
FILTER (
ALL ( 'Date' ),
'Date'[Year] = MAX ( 'Date'[Year] )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
EVALUATE
SUMMARIZECOLUMNS(
'Date'[Date],
FILTER('Date', 'Date'[Date] >= DATE(2018,5,1)),
"YTD", [Sales Amt YTD]
)
The issue with the way you wrote it, using CALCULATETABLE, is that you create an outside filter context on the 'Date'[Date] column that contains all dates starting from 2018-05-01. When evaluating the YTD logic inside the FILTER statement, MAX('Date'[Year]) uses this filter context, so that it returns whatever year is the largest on your entire 'Date' table (for example 2025).
Remember, that the CALCULATE function only applies a context transition (row context to filter context) when evaluating the first argument. The filter arguments are evaluated on the original filter context.
If you want to stick with your syntax, you could write an additional CALCULATE to force the context transition to apply also to the 2nd argument of the inner CALCULATE call:
EVALUATE
CALCULATETABLE(
ADDCOLUMNS (
VALUES ( 'Date'[Date] ),
"YTD",
CALCULATE( // Additional CALCULATE to force context transition on filter arguments
CALCULATE (
[Sales Amt],
FILTER (
ALL ( 'Date' ),
'Date'[Year] = MAX ( 'Date'[Year] )
&& 'Date'[Date] <= MAX ( 'Date'[Date] )
)
)
)
),
'Date'[Date] >= DATE(2018,5,1)
)
This would be the same as referencing the measure directly, as referencing a measure always does an implicit CALCULATE:
EVALUATE
CALCULATETABLE(
ADDCOLUMNS (
VALUES ( 'Date'[Date] ),
"YTD", [Sales Amt YTD]
),
'Date'[Date] >= DATE(2018,5,1)
)
I have a data model with a table called Transactions (below), and TranDate which is the date dimension.
I have a measure to calculate the opening balance for the first date that is visible in the pivot table.
Op Bal First Selected :=
VAR MinDate = CALCULATE (
MIN ( TranDates[Tran Date] ),
ALLSELECTED ( TranDates )
)
RETURN
CALCULATE (
SUM ( Transactions[Amount] ),
FILTER
(
ALL ( TranDates ),
TranDates[Tran Date] < MinDate
)
)
If I deselect Jan-16, I get the desired result below:
However, the measure only works in Excel 2016 and not Excel 2013, because variables are not supported in Excel 2013. If I replace the MinDate variable with the DAX expression, then the measure will return blanks because ALLSELECTED restores the context in the FILTER() function and not the context in the CALCULATE() function (i.e. MinDate is 1-Jan instead of 1-Feb).
Is there an equivalent DAX formula that works in Excel 2013 / SSAS 2014 (i.e. without using variables)?
After lots of trial and errors, here's the measure I defined:
Op Bal First Selected:=
MINX
(
ADDCOLUMNS (
ADDCOLUMNS
(
SUMMARIZE (
ALL(Transactions),
Transactions[Tran Date]
),
"MinDate",
CALCULATE (
MIN ( Transactions[Tran Date] ),
ALLSELECTED()
)
),
"Op Bal First Selected Calc",
CALCULATE (
SUM ( Transactions[Amount] ),
FILTER
(
ALL( Transactions ),
Transactions[Tran Date] < [MinDate]
)
)
),
[Op Bal First Selected Calc]
)
I used ALL() in the inner context so that the original filter context (i.e. pivot table selection) is preserved in the context just outside of ALLSELECTED().
If you want to use the TranDate table as the filter, you can define it as follows:
Op Bal First Selected:=
MINX
(
ADDCOLUMNS (
ADDCOLUMNS
(
SUMMARIZE (
ALLSELECTED(TranDates),
TranDates[Tran Date]
),
"MinDate",
CALCULATE (
MIN ( TranDates[Tran Date] )
)
),
"Op Bal First Selected Calc",
CALCULATE (
SUM ( Transactions[Amount] ),
FILTER
(
ALL( TranDates ),
TranDates[Tran Date] < [MinDate]
)
)
),
[Op Bal First Selected Calc]
)
IIF(SUM
(
[Calendar].[Month].CurrentMember.Lag(17) :
[Calendar].[Month].CurrentMember,
[Measures].[Qty]
) = 0, 0,
SUM
(
[Calendar].[Month].CurrentMember.Lag(17) :
[Calendar].[Month].CurrentMember,
[Measures].[Local Num]
) /
SUM
(
[Calendar].[Month].CurrentMember.Lag(17) :
[Calendar].[Month].CurrentMember,
[Measures].[N Qty]
) )
I am trying to convert that mdx query to dax formula. is there any simple way to write dax formula for that mdx query?
If it is a measure you need, try this:
ValueLast17Months:=
CALCULATE
(
DIVIDE(SUM([Local Num]),SUM([N Qty])),
DATESINPERIOD
(
'Calendar'[Month],
MAX('Calendar'[Month]),
-17,
MONTH
)
)
If it was a calculated column you needed, this can work:
ValueLast17Months
= DIVIDE(
SUMX(
FILTER
(
'Calendar',
MONTH('Calendar'[Month]) + 17 >= MONTH(EARLIER('Calendar'[Month])) &&
MONTH('Calendar'[Month]) <= MONTH(EARLIER('Calendar'[Month]))
)
,[Local Num]
)
,
SUMX(
FILTER
(
'Calendar',
MONTH('Calendar'[Month]) + 17 >= MONTH(EARLIER('Calendar'[Month])) &&
MONTH('Calendar'[Month]) <= MONTH(EARLIER('Calendar'[Month]))
)
,[N Qty]
)
)
