Anyone have a clue how I can calculate the following DAX equation for the same period last year?
Solved! Go to Solution.
Hi @kajelliott ,
I am not sure how your semantic model looks like, please try the following code as shown below.
Previous Est Value =
CALCULATE (
SUMX (
FILTER (
'table',
'table'[Created On] <= MAX ( 'Calendar'[Date] )
&& (
ISBLANK ( 'table'[Close Date] )
|| 'table'[Close Date] > MAX ( 'Calendar'[Date] )
)
),
( 'table'[Est. Revenue] )
),
CROSSFILTER ( 'table'[Created On], 'Calendar'[Date], NONE ),
SAMEPERIODLASTYEAR ( 'Calendar'[Date] )
)
If I've misunderstood you, please provide detailed sample data and the results you are hoping for. We can better understand the problem and help you. Show it as a screenshot or excel. Please remove any sensitive data in advance.
Best Regards,
Yulia Yan

I believe this worked, thank you!
@kajelliott you can use the SAMEPERIODLASTYEAR function. Modify your DAX formula as follows:
SamePeriodLastYear Est Value =
CALCULATE(
SUMX(
FILTER(
ALL('table'),
'table'[Created On]
>= SAMEPERIODLASTYEAR(MAX('Calendar'[Date]))
&& (ISBLANK('table'[Close Date]) || 'table'[Close Date] > SAMEPERIODLASTYEAR(MAX('Calendar'[Date])))
),
'table'[Est. Revenue]
),
CROSSFILTER('table'[Created On], 'Calendar'[Date], NONE)
)@DallasBaba - thanks for your suggestion!
Coming up with an error around the calendar date when SAMEPERIODLASTYEAR is included in the expression.
Error states 'The first argument to 'SAMEPERIODLASTYEAR' must specify a column'
