Measure to Column

Hi,

I currently have a measure

VAR __SelectedDate = MAX('Log_Activation'[DateTime])
VAR __Table1 = FILTER(ALL('Log_Activation'),[DateTime]<=__SelectedDate)
VAR __Table2 = FILTER(ALL('Log_Activation'),[DateTime]<__SelectedDate)
VAR __Device1 = DISTINCT(SELECTCOLUMNS(__Table1,"Device",[Name]))
VAR __Device2 = DISTINCT(SELECTCOLUMNS(__Table2,"Device",[Name]))
VAR __Table = EXCEPT(__Device1, __Device2)
VAR __Devices = DISTINCT(SELECTCOLUMNS(__Table,"Device",[Device]))
RETURN
CONCATENATEX(__Devices,[Device],",")

 

I am wondering if there is any way I can change it to a column.


Thanks

Hi @martcatnip ,

 

As @Greg_Deckler  said, if you want dynamic results, calculated columns are not recommended. If it is a static result, you can modify it to

 

Calculated Column =
VAR __Table1 =
    FILTER (
        ALL ( 'Log_Activation' ),
        [DateTime] <= EARLIER ( 'Log_Activation'[DateTime] )
    )
VAR __Table2 =
    FILTER (
        ALL ( 'Log_Activation' ),
        [DateTime] < EARLIER ( 'Log_Activation'[DateTime] )
    )
VAR __Device1 =
    DISTINCT ( SELECTCOLUMNS ( __Table1, "Device", [Name] ) )
VAR __Device2 =
    DISTINCT ( SELECTCOLUMNS ( __Table2, "Device", [Name] ) )
VAR __Table =
    EXCEPT ( __Device1, __Device2 )
VAR __Devices =
    DISTINCT ( SELECTCOLUMNS ( __Table, "Device", [Device] ) )
RETURN
    CONCATENATEX ( __Devices, [Device], "," )

 

 

The calculated column will use EARLIER to get the current row.

@martcatnip In your case, no if you want it to remain dynamic based upon user interaction. Calculated columns are only recaculated at the time of data load/refresh. Now, if it doesn't need to be dynamic and your "__SelectedDate" can be based on something like a [Date] column in your table, then just set it to that and in theory the rest of the formula looks like it should be just fine.
