LAG Conversion from MDX to DAX
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 _valueBest Regards

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
