New table using variable and custom columns

Hi Anonymous ,

Sorry for that, but we cannot reproduce this issue on my side with your shared DAX code,

We created a sample “t_intervention” table, and then create two calculated tables with your code,  we got the  result as following,

We can also use ADDCOLUMNS function to add a column to tables, such as following:

a_calendrier_global =
VAR _mon_calendrier_ =
    CALENDAR (
        FIRSTDATE ( t_intervention[int_date_programmation].[Date] );
        LASTDATE ( t_intervention[int_date_programmation].[Date] )
    )
RETURN
ADDCOLUMNS ( _mon_calendrier_; "test"; "Hello world !" )

Could you please reproduce this issue with the latest version of Power BI Desktop ?  If  it does not contain any confidential information, could you please provided  a screenshot which contains error information.

BTW, pbix as attached.

Best regards,
