MoM quick measure and Date Hierarchy

[jofoster]

I am trying to use the MoM % increase quick measure.  I am counting distinct values of an item by month, and want to also plot the % increase of the previous month. The measure requires using the PowerBI Date Hierarchy, but the quick measure will not let me add  it?  What am I doing wrong?

here is my data:

and here is what I see when trying to add the month date Hierarchy. If i just add the Month, which it lets me do, I get an error saying I need to add the date Hierarchy.

Hi @jofoster ,

You need to add the column of Month to the date field rather than just put month to it. The quick measure will calculate automatically based on  month.

NOt sure I understand. When I add the month, get the error that it requires the date hierarchy. But it will not let me add the data hierarchy?

Count of SubscriptionGUID MoM% =

IF(

    ISFILTERED('Deployments to Azure'[Month]),

    ERROR("Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column."),

    VAR __PREV_MONTH =

        CALCULATE(

            DISTINCTCOUNT('Deployments to Azure'[SubscriptionGUID]),

            DATEADD('Deployments to Azure'[Month].[Date], -1, MONTH)

        )

    RETURN

        DIVIDE(

            DISTINCTCOUNT('Deployments to Azure'[SubscriptionGUID])

                - __PREV_MONTH,

            __PREV_MONTH

        )

)
