Hi All,
I've the following MDX formula i'm trying to convert to DAX:
([Time Dimension].[Date].CurrentMember.lag(1), [Measures].[Total Available])
I've been trying to adjust the code below so I can retrieve the previous months 'Total Available' value but i'm only seem to be just getting the one singular previous month value:
PrevMonth = CALCULATE(
[Total Available],
ALLEXCEPT(TEST_TABLE,TEST_TABLE[DATE]),
DATEADD([DATE],-1,MONTH)
)
Any pointers would be appreciated.
Cheers
Solved! Go to Solution.
Hi @GillyGils ,
If there are only 'End of Month Dates' in your fact table. Please have a try.
Create a measure.
Measure1 =
VAR _date =
MAX ( 'Table'[date] )
VAR _pre_date =
EOMONTH ( _date,-1)
VAR _value =
CALCULATE (
[total available],
FILTER ( ALL ( 'Table'), 'Table'[date] = _pre_date )
)
RETURN
_value

Hi Polly,
The code you provided is working for me as expected. I had use to EOMONTH, as I only have 'End of Month Dates' in my fact table:
Measure =
VAR _date =
MAX ( 'Table'[date] )
VAR _pre_date =
EOMONTH ( _date, -1 )
VAR _value =
CALCULATE (
[total available],
FILTER ( ALL ( 'Table'[date], 'Table'[total] ), 'Table'[date] = _pre_date )
)
RETURN
_value
One quick additonal question, when I drag in a Date Hierarchy of Time Dimension, the values are then empty:
Do I add another FILTER conidition to the DAX query?
Thanks

Thank you Polly. This works perfectly.
Still getting a hang of the DAX syntax and this is helping me understand it more.
Thank you.
Hi @GillyGils ,
I have created a simple sample, please refer to it to see if it helps you.
Create a measure.
Measure =
VAR _date =
MAX ( 'Table'[date] )
VAR _pre_date =
EDATE ( _date, -1 )
VAR _value =
CALCULATE (
[total available],
FILTER ( ALL ( 'Table'[date], 'Table'[total] ), 'Table'[date] = _pre_date )
)
RETURN
_value
If I have misunderstood your meaning, please provide more details with your desired output and pbix file without priavcy information.
